Why does an image captured using camera intent gets rotated on some devices on Android?

I'm capturing an image and setting it to image view.

public void captureImage() {

    Intent intentCamera = new Intent("android.media.action.IMAGE_CAPTURE");
    File filePhoto = new File(Environment.getExternalStorageDirectory(), "Pic.jpg");
    imageUri = Uri.fromFile(filePhoto);
    MyApplicationGlobal.imageUri = imageUri.getPath();
    intentCamera.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
    startActivityForResult(intentCamera, TAKE_PICTURE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intentFromCamera) {
    super.onActivityResult(requestCode, resultCode, intentFromCamera);

    if (resultCode == RESULT_OK && requestCode == TAKE_PICTURE) {

        if (intentFromCamera != null) {
            Bundle extras = intentFromCamera.getExtras();
            if (extras.containsKey("data")) {
                bitmap = (Bitmap) extras.get("data");
            }
            else {
                bitmap = getBitmapFromUri();
            }
        }
        else {
            bitmap = getBitmapFromUri();
        }
        // imageView.setImageBitmap(bitmap);
        imageView.setImageURI(imageUri);
    }
    else {
    }
}

public Bitmap getBitmapFromUri() {

    getContentResolver().notifyChange(imageUri, null);
    ContentResolver cr = getContentResolver();
    Bitmap bitmap;

    try {
        bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, imageUri);
        return bitmap;
    }
    catch (Exception e) {
        e.printStackTrace();
        return null;
    }
}

But the problem is, the image on some devices every time it gets rotated. For example, on a Samsung device it works good, but on a Sony Xperia the image gets rotated by 90 degrees and on Toshiba Thrive (tablet) by 180 degrees.

Most phone cameras are landscape, meaning if you take the photo in portrait, the resulting photos will be rotated 90 degrees. In this case, the camera software should populate the Exif data with the orientation that the photo should be viewed in.

Note that the below solution depends on the camera software/device manufacturer populating the Exif data, so it will work in most cases, but it is not a 100% reliable solution.

ExifInterface ei = new ExifInterface(photoPath);
int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION,
                                     ExifInterface.ORIENTATION_UNDEFINED);

Bitmap rotatedBitmap = null;
switch(orientation) {

    case ExifInterface.ORIENTATION_ROTATE_90:
        rotatedBitmap = rotateImage(bitmap, 90);
        break;

    case ExifInterface.ORIENTATION_ROTATE_180:
        rotatedBitmap = rotateImage(bitmap, 180);
        break;

    case ExifInterface.ORIENTATION_ROTATE_270:
        rotatedBitmap = rotateImage(bitmap, 270);
        break;

    case ExifInterface.ORIENTATION_NORMAL:
    default:
        rotatedBitmap = bitmap;
}

Here is the rotateImage method:

public static Bitmap rotateImage(Bitmap source, float angle) {
    Matrix matrix = new Matrix();
    matrix.postRotate(angle);
    return Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(),
                               matrix, true);
}

By combining Jason Robinson's answer with Felix's answer and filling the missing parts, here is the final complete solution for this issue that will do the following after testing it on Android Android 4.1 (Jelly Bean), Android 4.4 (KitKat) and Android 5.0 (Lollipop).

Steps

1. Scale down the image if it was bigger than 1024x1024.

2. Rotate the image to the right orientation only if it was rotate 90, 180 or 270 degree.

3. Recycle the rotated image for memory purposes.

Here is the code part:

Call the following method with the current Context and the image URI that you want to fix

/**
 * This method is responsible for solving the rotation issue if exist. Also scale the images to
 * 1024x1024 resolution
 *
 * @param context       The current context
 * @param selectedImage The Image URI
 * @return Bitmap image results
 * @throws IOException
 */
public static Bitmap handleSamplingAndRotationBitmap(Context context, Uri selectedImage)
        throws IOException {
    int MAX_HEIGHT = 1024;
    int MAX_WIDTH = 1024;

    // First decode with inJustDecodeBounds=true to check dimensions
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    InputStream imageStream = context.getContentResolver().openInputStream(selectedImage);
    BitmapFactory.decodeStream(imageStream, null, options);
    imageStream.close();

    // Calculate inSampleSize
    options.inSampleSize = calculateInSampleSize(options, MAX_WIDTH, MAX_HEIGHT);

    // Decode bitmap with inSampleSize set
    options.inJustDecodeBounds = false;
    imageStream = context.getContentResolver().openInputStream(selectedImage);
    Bitmap img = BitmapFactory.decodeStream(imageStream, null, options);

    img = rotateImageIfRequired(context, img, selectedImage);
    return img;
}

Here is the CalculateInSampleSize method from the pre mentioned source:

/**
  * Calculate an inSampleSize for use in a {@link BitmapFactory.Options} object when decoding
  * bitmaps using the decode* methods from {@link BitmapFactory}. This implementation calculates
  * the closest inSampleSize that will result in the final decoded bitmap having a width and
  * height equal to or larger than the requested width and height. This implementation does not
  * ensure a power of 2 is returned for inSampleSize which can be faster when decoding but
  * results in a larger bitmap which isn't as useful for caching purposes.
  *
  * @param options   An options object with out* params already populated (run through a decode*
  *                  method with inJustDecodeBounds==true
  * @param reqWidth  The requested width of the resulting bitmap
  * @param reqHeight The requested height of the resulting bitmap
  * @return The value to be used for inSampleSize
  */
private static int calculateInSampleSize(BitmapFactory.Options options,
                                         int reqWidth, int reqHeight) {
    // Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) {

        // Calculate ratios of height and width to requested height and width
        final int heightRatio = Math.round((float) height / (float) reqHeight);
        final int widthRatio = Math.round((float) width / (float) reqWidth);

        // Choose the smallest ratio as inSampleSize value, this will guarantee a final image
        // with both dimensions larger than or equal to the requested height and width.
        inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;

        // This offers some additional logic in case the image has a strange
        // aspect ratio. For example, a panorama may have a much larger
        // width than height. In these cases the total pixels might still
        // end up being too large to fit comfortably in memory, so we should
        // be more aggressive with sample down the image (=larger inSampleSize).

        final float totalPixels = width * height;

        // Anything more than 2x the requested pixels we'll sample down further
        final float totalReqPixelsCap = reqWidth * reqHeight * 2;

        while (totalPixels / (inSampleSize * inSampleSize) > totalReqPixelsCap) {
            inSampleSize++;
        }
    }
    return inSampleSize;
}

Then comes the method that will check the current image orientation to decide the rotation angle

 /**
 * Rotate an image if required.
 *
 * @param img           The image bitmap
 * @param selectedImage Image URI
 * @return The resulted Bitmap after manipulation
 */
private static Bitmap rotateImageIfRequired(Context context, Bitmap img, Uri selectedImage) throws IOException {

InputStream input = context.getContentResolver().openInputStream(selectedImage);
ExifInterface ei;
if (Build.VERSION.SDK_INT > 23)
    ei = new ExifInterface(input);
else
    ei = new ExifInterface(selectedImage.getPath());
		
    int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);

    switch (orientation) {
        case ExifInterface.ORIENTATION_ROTATE_90:
            return rotateImage(img, 90);
        case ExifInterface.ORIENTATION_ROTATE_180:
            return rotateImage(img, 180);
        case ExifInterface.ORIENTATION_ROTATE_270:
            return rotateImage(img, 270);
        default:
            return img;
    }
}

Finally the rotation method itself

private static Bitmap rotateImage(Bitmap img, int degree) {
    Matrix matrix = new Matrix();
    matrix.postRotate(degree);
    Bitmap rotatedImg = Bitmap.createBitmap(img, 0, 0, img.getWidth(), img.getHeight(), matrix, true);
    img.recycle();
    return rotatedImg;
}

-Don't forget to vote up for those guys answers for their efforts and Shirish Herwade who asked this helpful question.

It's easy to detect the image orientation and replace the bitmap using:

 /**
 * Rotate an image if required.
 * @param img
 * @param selectedImage
 * @return
 */
private static Bitmap rotateImageIfRequired(Context context,Bitmap img, Uri selectedImage) {

    // Detect rotation
    int rotation = getRotation(context, selectedImage);
    if (rotation != 0) {
        Matrix matrix = new Matrix();
        matrix.postRotate(rotation);
        Bitmap rotatedImg = Bitmap.createBitmap(img, 0, 0, img.getWidth(), img.getHeight(), matrix, true);
        img.recycle();
        return rotatedImg;
    }
    else{
        return img;
    }
}

/**
 * Get the rotation of the last image added.
 * @param context
 * @param selectedImage
 * @return
 */
private static int getRotation(Context context,Uri selectedImage) {

    int rotation = 0;
    ContentResolver content = context.getContentResolver();

    Cursor mediaCursor = content.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                                       new String[] { "orientation", "date_added" },
                                       null, null, "date_added desc");

    if (mediaCursor != null && mediaCursor.getCount() != 0) {
        while(mediaCursor.moveToNext()){
            rotation = mediaCursor.getInt(0);
            break;
        }
    }
    mediaCursor.close();
    return rotation;
}

To avoid Out of memories with big images, I'd recommend you to rescale the image using:

private static final int MAX_HEIGHT = 1024;
private static final int MAX_WIDTH = 1024;
public static Bitmap decodeSampledBitmap(Context context, Uri selectedImage)
    throws IOException {

    // First decode with inJustDecodeBounds=true to check dimensions
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    InputStream imageStream = context.getContentResolver().openInputStream(selectedImage);
    BitmapFactory.decodeStream(imageStream, null, options);
    imageStream.close();

    // Calculate inSampleSize
    options.inSampleSize = calculateInSampleSize(options, MAX_WIDTH, MAX_HEIGHT);

    // Decode bitmap with inSampleSize set
    options.inJustDecodeBounds = false;
    imageStream = context.getContentResolver().openInputStream(selectedImage);
    Bitmap img = BitmapFactory.decodeStream(imageStream, null, options);

    img = rotateImageIfRequired(img, selectedImage);
    return img;
}

It's not posible to use ExifInterface to get the orientation because an Android OS issue: https://code.google.com/p/android/issues/detail?id=19268

And here is calculateInSampleSize

/**
 * Calculate an inSampleSize for use in a {@link BitmapFactory.Options} object when decoding
 * bitmaps using the decode* methods from {@link BitmapFactory}. This implementation calculates

 */
public static int calculateInSampleSize(BitmapFactory.Options options,
                                        int reqWidth, int reqHeight) {

    // Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) {

        // Calculate ratios of height and width to requested height and width
        final int heightRatio = Math.round((float) height / (float) reqHeight);
        final int widthRatio = Math.round((float) width / (float) reqWidth);

        // Choose the smallest ratio as inSampleSize value, this will guarantee a final image
        // with both dimensions larger than or equal to the requested height and width.
        inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;

        // This offers some additional logic in case the image has a strange
        // aspect ratio. For example, a panorama may have a much larger
        // width than height. In these cases the total pixels might still
        // end up being too large to fit comfortably in memory, so we should

        final float totalPixels = width * height;

        // Anything more than 2x the requested pixels we'll sample down further
        final float totalReqPixelsCap = reqWidth * reqHeight * 2;

        while (totalPixels / (inSampleSize * inSampleSize) > totalReqPixelsCap) {
            inSampleSize++;
        }
    }
    return inSampleSize;
}

One line solution:

Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);

Or

Picasso.with(context).load("file:" + photoPath).into(imageView);

This will autodetect rotation and place image in correct orientation

Picasso is a very powerful library for handling images in your app includes: Complex image transformations with minimal memory use.

I have spent a lot of time looking for solution for this. And finally managed to do this. Don't forget to upvote @Jason Robinson answer because my is based on his.

So first thing, you sholuld know that since Android 7.0 we have to use FileProvider and something called ContentUri, otherwise you will get an annoying error trying to invoke your Intent. This is sample code:

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, getUriFromPath(context, "[Your path to save image]"));
startActivityForResult(intent, CAPTURE_IMAGE_RESULT);

Method getUriFromPath(Context, String) basis on user version of Android create FileUri (file://...) or ContentUri (content://...) and there it is:

public Uri getUriFromPath(Context context, String destination) {
	File file =  new File(destination);

	if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
		return FileProvider.getUriForFile(context, context.getPackageName() + ".provider", file);
	} else {
		return Uri.fromFile(file);
	}
}

After onActivityResult you can catch that uri where image is saved by camera, but now you have to detect camera rotation, here we will use moddified @Jason Robinson answer:

First we need to create ExifInterface based on Uri

@Nullable
public ExifInterface getExifInterface(Context context, Uri uri) {
	try {
		String path = uri.toString();
		if (path.startsWith("file://")) {
			return new ExifInterface(path);
		}
		if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
			if (path.startsWith("content://")) {
				InputStream inputStream = context.getContentResolver().openInputStream(uri);
				return new ExifInterface(inputStream);
			}
		}
	}
	catch (IOException e) {
		e.printStackTrace();
	}
	return null;
}

Above code can be simplified, but i want to show everything. So from FileUri we can create ExifInterface based on String path, but from ContentUri we can't, Android doesn't support that.

In that case we have to use other constructor based on InputStream. Remember this constructor isn't available by default, you have to add additional library:

compile "com.android.support:exifinterface:XX.X.X"

Now we can use getExifInterface method to get our angle:

public float getExifAngle(Context context, Uri uri) {
	try {
		ExifInterface exifInterface = getExifInterface(context, uri);
		if(exifInterface == null) {
			return -1f;
		}

		int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION,
				ExifInterface.ORIENTATION_UNDEFINED);

		switch (orientation) {
			case ExifInterface.ORIENTATION_ROTATE_90:
				return 90f;
			case ExifInterface.ORIENTATION_ROTATE_180:
				return 180f;
			case ExifInterface.ORIENTATION_ROTATE_270:
				return 270f;
			case ExifInterface.ORIENTATION_NORMAL:
				return 0f;
			case ExifInterface.ORIENTATION_UNDEFINED:
				return -1f;
			default:
				return -1f;
		}
	}
	catch (Exception e) {
		e.printStackTrace();
		return -1f;
	}
}

Now you have Angle to properly rotate you image :).

You can just read the orientation of the camera sensor like indicated by Google in the documentation: https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics.html

SENSOR_ORIENTATION

Added in API level 21
Key<Integer> SENSOR_ORIENTATION
Clockwise angle through which the output image needs to be rotated to be upright on the device screen in its native orientation.

Also defines the direction of rolling shutter readout, which is from top to bottom in the sensor's coordinate system.

Units: Degrees of clockwise rotation; always a multiple of 90

Range of valid values:
0, 90, 180, 270

This key is available on all devices.

Sample code:

CameraManager manager = (CameraManager) getSystemService(Context.CAMERA_SERVICE);
int orientation = 0;
try {
    String cameraId = manager.getCameraIdList()[0];
    CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraId);
    orientation = characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
}
catch (Exception e)
{
}

Jason Robinson's answer and Sami Eltamawy answer are excelent.

Just an improvement to complete the aproach, you should use compat ExifInterface.

com.android.support:exifinterface:${lastLibVersion}

You will be able to instantiate the ExifInterface(pior API <24) with InputStream (from ContentResolver) instead of uri paths avoiding "File not found exceptions"

https://android-developers.googleblog.com/2016/12/introducing-the-exifinterface-support-library.html

Normally it is recommended to solve the problem with the ExifInterface, like @Jason Robinson did suggest. If this approach doesn't work, you could try to look up the Orientation of the latest image taken...

private int getImageOrientation(){
    final String[] imageColumns = { MediaStore.Images.Media._ID, MediaStore.Images.ImageColumns.ORIENTATION };
    final String imageOrderBy = MediaStore.Images.Media._ID+" DESC";
    Cursor cursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
    		imageColumns, null, null, imageOrderBy);

    if(cursor.moveToFirst()){
        int orientation = cursor.getInt(cursor.getColumnIndex(MediaStore.Images.ImageColumns.ORIENTATION));
        cursor.close();
        return orientation;
    } else {
        return 0;
    }
}

Sadly, @jason-robinson answer above didn't work for me.

Although the rotate function works perfectly:

public static Bitmap rotateImage(Bitmap source, float angle) {
    Matrix matrix = new Matrix();
    matrix.postRotate(angle);
    return Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(), matrix,
            true);
}

I had to do the following to get the orientation as the Exif orientation was always 0

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
	super.onActivityResult(requestCode,resultCode,data);
    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && data != null) {
			Uri selectedImage = data.getData();
			String[] orientationColumn = {MediaStore.Images.Media.ORIENTATION};
			Cursor cur = managedQuery(imageUri, orientationColumn, null, null, null);
			int orientation = -1;
			if (cur != null && cur.moveToFirst()) {
					orientation = cur.getInt(cur.getColumnIndex(orientationColumn[0]));
			}
			InputStream imageStream = getContentResolver().openInputStream(selectedImage);
			Bitmap bitmap = BitmapFactory.decodeStream(imageStream);
			switch(orientation) {
					case 90:
							bitmap = rotateImage(chosen_image_bitmap, 90);
							break;
					case 180:
							bitmap = rotateImage(chosen_image_bitmap, 180);
							break;
					case 270:
							bitmap = rotateImage(chosen_image_bitmap, 270);
							break;
					default:
							break;
			}
			imageView.setImageBitmap(bitmap );

I created a Kotlin extension function that simplifies the operation for Kotlin developers based on @Jason Robinson's answer. I hope it helps.

fun Bitmap.fixRotation(uri: Uri): Bitmap? {

    val ei = ExifInterface(uri.path)

    val orientation: Int = ei.getAttributeInt(
        ExifInterface.TAG_ORIENTATION,
        ExifInterface.ORIENTATION_UNDEFINED
    )

    return when (orientation) {
        ExifInterface.ORIENTATION_ROTATE_90 -> rotateImage( 90f)
        ExifInterface.ORIENTATION_ROTATE_180 -> rotateImage( 180f)
        ExifInterface.ORIENTATION_ROTATE_270 -> rotateImage( 270f)
        ExifInterface.ORIENTATION_NORMAL -> this
        else -> this
    }
}

fun Bitmap.rotateImage(angle: Float): Bitmap? {
    val matrix = Matrix()
    matrix.postRotate(angle)
    return Bitmap.createBitmap(
        this, 0, 0, width, height,
        matrix, true
    )
}

I solved it using a different method. All you have to do is check if the width is greater than height

Matrix rotationMatrix = new Matrix();
if(finalBitmap.getWidth() >= finalBitmap.getHeight()){
    rotationMatrix.setRotate(-90);
}else{
    rotationMatrix.setRotate(0);
}

Bitmap rotatedBitmap = Bitmap.createBitmap(finalBitmap,0,0,finalBitmap.getWidth(),finalBitmap.getHeight(),rotationMatrix,true);

The selected answer uses the most common method answered to this and similar questions. However, it does not work with both front and back cameras on Samsung. For those looking for a solution which works across both front and back cameras for Samsung and other major manufacturers, this answer by nvhausid is awesome:

https://stackoverflow.com/a/18915443/6080472

For those who don't want to click through, the relevant magic is to use the CameraInfo rather then relying on EXIF.

Bitmap realImage = BitmapFactory.decodeByteArray(data, 0, data.length);
android.hardware.Camera.CameraInfo info = new android.hardware.Camera.CameraInfo();
android.hardware.Camera.getCameraInfo(mCurrentCameraId, info);
Bitmap bitmap = rotate(realImage, info.orientation);

Full code in the link.

If somebody experiences problems with ExifInterface on Android 4.4 (KitKat) for getting the orientation, it might be because of wrong path got from the URI. See a solution for propoer getPath in Stack Overflow question https://stackoverflow.com/questions/20067508/get-real-path-from-uri-android-kitkat-new-storage-access-framework/20559175#20559175

Find below link this solution is The best https://www.samieltamawy.com/how-to-fix-the-camera-intent-rotated-image-in-android/

here a solution that is based on the ones above but only needs context and the image file as inputs

public static Bitmap rectifyImage(Context context,File imageFile){
    Bitmap originalBitmap= BitmapFactory.decodeFile(imageFile.getAbsolutePath());
    try{
        Uri uri=Uri.fromFile(imageFile);
        InputStream input = context.getContentResolver().openInputStream(uri);
        ExifInterface ei;
        
        if (Build.VERSION.SDK_INT > 23)
            ei = new ExifInterface(input);
        else
            ei = new ExifInterface(uri.getPath());

        int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
        switch (orientation) {
            case ExifInterface.ORIENTATION_ROTATE_90:
                return rotateImage(originalBitmap, 90);
            case ExifInterface.ORIENTATION_ROTATE_180:
                return rotateImage(originalBitmap, 180);
            case ExifInterface.ORIENTATION_ROTATE_270:
                return rotateImage(originalBitmap, 270);
            default:
                return originalBitmap;
        }
    }catch (Exception e){
        return originalBitmap;
    }
}

public static Bitmap rotateImage(Bitmap source, float angle) {
    Matrix matrix = new Matrix();
    matrix.postRotate(angle);
    return Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(),
            matrix, true);
}

Better try to take the picture in a specific orientation.

android:screenOrientation="landscape"
android:configChanges="orientation|keyboardHidden"

For best results give landscape orientation in the cameraview activity.

This maybe goes without saying but always remember that you can handle some of these image handling issues on your server. I used responses like the ones contained in this thread to handle the immediate display of the image. However my application requires images to be stored on the server (this is probably a common requirement if you want the image to persist as users switch phones).

The solutions contained in many of the threads concerning this topic don't discuss the lack of persistence of the EXIF data which doesn't survive the Bitmap's image compression, meaning you'll need to rotate the image each time your server loads it. Alternatively, you can send the EXIF orientation data to your server, and then rotate the image there if needed.

It was easier for me to create a permanent solution on a server because I didn't have to worry about Android's clandestine file paths.

The simplest solution for this problem:

captureBuilder.set(CaptureRequest.JPEG_ORIENTATION,
                   characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION));

I am saving the image in jpg format.

Below code worked with me, it got the bitmap from the fileUri, and do the rotation fixing if required:

    private fun getCapturedImage(selectedPhotoUri: Uri): Bitmap {
        val bitmap = when {
            Build.VERSION.SDK_INT < 28 -> MediaStore.Images.Media.getBitmap(
                this.contentResolver,
                selectedPhotoUri
            )
            else -> {
                val source = ImageDecoder.createSource(this.contentResolver, selectedPhotoUri)
                ImageDecoder.decodeBitmap(source)
            }
        }

        // If the image is rotated, fix it
        return when (ExifInterface(contentResolver.run { openInputStream(selectedPhotoUri) }).getAttributeInt(
            ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_UNDEFINED)) {
            ExifInterface.ORIENTATION_ROTATE_90 ->
                Bitmap.createBitmap(bitmap, 0, 0, bitmap.width, bitmap.height, Matrix().apply {
                    postRotate(90F) }, true)
            ExifInterface.ORIENTATION_ROTATE_180 ->
                Bitmap.createBitmap(bitmap, 0, 0, bitmap.width, bitmap.height, Matrix().apply {
                    postRotate(180F) }, true)
            ExifInterface.ORIENTATION_ROTATE_270 ->
                Bitmap.createBitmap(bitmap, 0, 0, bitmap.width, bitmap.height, Matrix().apply {
                    postRotate(270F) }, true)
            else -> bitmap
        } 
    }

Here is Xamarin.Android version:

From @Jason Robinson's answer:

Bitmap rotate(Bitmap bitmap, int angle)
{
    var matrix = new Matrix();
    matrix.PostRotate(angle);

    return Bitmap.CreateBitmap(bitmap, 0, 0, bitmap.Width, bitmap.Height, matrix, true);
}

Bitmap rotateIfRequired(Bitmap bitmap, string imagePath)
{
    var ei = new ExifInterface(imagePath);
    var orientation = ei.GetAttributeInt(ExifInterface.TagOrientation, (int)Android.Media.Orientation.Undefined);

    switch (orientation)
    {
        case (int)Android.Media.Orientation.Rotate90: return rotate(bitmap, 90);
        case (int)Android.Media.Orientation.Rotate180: return rotate(bitmap, 180);
        case (int)Android.Media.Orientation.Rotate270: return rotate(bitmap, 270);
        default: return bitmap;
    }
}

Then calculateInSampleSize method:

int calculateInSampleSize(BitmapFactory.Options options, int reqW, int reqH)
{
    float h = options.OutHeight;
    float w = options.OutWidth;
    var inSampleSize = 1;

    if (h > reqH || w > reqW)
    {
        if (reqH == 0) inSampleSize = (int)Math.Floor(w / reqW);
        else if (reqW == 0) inSampleSize = (int)Math.Floor(h / reqH);
        else
        {
            var hRatio = (int)Math.Floor(h / reqH);
            var wRatio = (int)Math.Floor(w / reqW);
            inSampleSize = false ? Math.Max(hRatio, wRatio) : Math.Min(hRatio, wRatio);
        }
    }

    return inSampleSize;
}

From @Sami Eltamawy's answer:

Bitmap handleSamplingAndRotationBitmap(string imagePath)
{
    var maxHeight = 1024;
    var maxWidth = 1024;

    var options = new BitmapFactory.Options();
    options.InJustDecodeBounds = true;
    BitmapFactory.DecodeFile(imagePath, options);

    options.InSampleSize = calculateInSampleSize(options, maxWidth, maxHeight);

    options.InJustDecodeBounds = false;

    var bitmap = BitmapFactory.DecodeFile(imagePath, options);

    bitmap = rotateIfRequired(bitmap, imagePath);

    return bitmap;
}

If you are using Fresco, you can use this -

final ImageRequest imageRequest = ImageRequestBuilder.newBuilderWithSource(uri)
.setRotationOptions(RotationOptions.autoRotate())
.build();

mSimpleDraweeView.setController(
Fresco.newDraweeControllerBuilder()
    .setImageRequest(imageRequest)
    .build());

This automatically rotates the images based on Exif data.

Source: https://frescolib.org/docs/rotation.html

Got an answer for this problem without using ExifInterface. We can get the rotation of the camera either front camera or back camera whichever you are using then while creating the Bitmap we can rotate the bitmap using Matrix.postRotate(degree)

public int getRotationDegree() {
    int degree = 0;

    for (int i = 0; i < Camera.getNumberOfCameras(); i++) {
        Camera.CameraInfo info = new Camera.CameraInfo();
        Camera.getCameraInfo(i, info);
        if (info.facing == Camera.CameraInfo.CAMERA_FACING_BACK) {
            degree = info.orientation;

            return degree;
        }
    }

    return degree;
}

After calculating the rotation you can rotate you bitmap like below:

 Matrix matrix = new Matrix();

 matrix.postRotate(getRotationDegree());

 Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight(), matrix, true);

Herare bm should be your bitmap.

If you want to know the rotation of your front camera just change Camera.CameraInfo.CAMERA_FACING_BACK to Camera.CameraInfo.CAMERA_FACING_FRONT above.

I hope this helps.

Use of Glide library worked for me. Rotation is taken cared of automatically.

Bitmap bitmap = Glide.with(myContext).asBitmap().load(imageFilePath).submit(SIZE_ORIGINAL, SIZE_ORIGINAL).get();

Then you save that bitmap to a file in JPEG format, for example.

If you just want to load into an ImageView instead of saving to a file:

Glide.with(myContext).load(imageFilePath).into(myImageView)

by using glide lib you can get image with exact orientation not need to check rotation

in kotlin

CoroutineScope(Dispatchers.IO).launch {
         var bitmap = Glide.with(context).asBitmap().load(imagePathOrUriOrLink)
                /*.apply(
                    RequestOptions()
                        .override(MAXIMUM_IMAGE_RESOLUTION)
                )*/ //uncomment it if you want original image
                /*.diskCacheStrategy(DiskCacheStrategy.NONE).skipMemoryCache(true)*/ //uncomment it you want to not cache image
                .submit().get()//this is synchronous approach  
}

using this dependency

api 'com.github.bumptech.glide:glide:4.12.0'
kapt 'com.github.bumptech.glide:compiler:4.12.0'

There is a more simple command to fix this error.

Just simply add after yourImageView.setBitmap(bitmap); this yourImageView.setRotation(90);

This fixed mine. Hope it helps !
