Camera orientation issue in Android

I am building an application that uses camera to take pictures. Here is my source code to do this:

		File file = new File(Environment.getExternalStorageDirectory(),
			imageFileName);
	imageFilePath = file.getPath();
	Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
	//Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
	intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
	startActivityForResult(intent, ACTIVITY_NATIVE_CAMERA_AQUIRE);

On onActivityResult() method, I use BitmapFactory.decodeStream() to pickup the image.

When I run my application on Nexus one, it runs well. But when I run on Samsung Galaxy S or HTC Inspire 4G, the image's direction is not correct.

• Capture with portrait mode, the real image (save on SD card) always rotates 90 degree.

Image preview after shot --------- Real image on SD card

• Capture with landscape mode, all things are good.

Image preview after shot --------- Real image on SD card

There are quite a few similar topics and issues around here. Since you're not writing your own camera, I think it boils down to this:

some devices rotate the image before saving it, while others simply add the orientation tag in the photo's exif data.

I'd recommend checking the photo's exif data and looking particularly for

ExifInterface exif = new ExifInterface(SourceFileName);     //Since API Level 5
String exifOrientation = exif.getAttribute(ExifInterface.TAG_ORIENTATION);

Since the photo is displaying correctly in your app, i'm not sure where the problem is, but this should definitely set you on the right path!

I just encountered the same issue, and used this to correct the orientation:

public void fixOrientation() {
	if (mBitmap.getWidth() > mBitmap.getHeight()) {
    	Matrix matrix = new Matrix();
    	matrix.postRotate(90);
    	mBitmap = Bitmap.createBitmap(mBitmap , 0, 0, mBitmap.getWidth(), mBitmap.getHeight(), matrix, true);
	}
}

If the width of the Bitmap is greater than the height, the returned image is in landscape, so I rotate it 90 degrees.

Hope it helps anyone else with this issue.

There are two things needed:

1. Camera preview need the same as your rotation. Set this by camera.setDisplayOrientation(result);

2. Save the picture captured as your camera preview. Do this via Camera.Parameters.

    int mRotation = getCameraDisplayOrientation();
   
    Camera.Parameters parameters = camera.getParameters();
   
    parameters.setRotation(mRotation); //set rotation to save the picture
   
    camera.setDisplayOrientation(result); //set the rotation for preview camera
   
    camera.setParameters(parameters);
   

Hope that helps.

            int rotate = 0;
            try {
                File imageFile = new File(sourcepath);
                ExifInterface exif = new ExifInterface(
                        imageFile.getAbsolutePath());
                int orientation = exif.getAttributeInt(
                        ExifInterface.TAG_ORIENTATION,
                        ExifInterface.ORIENTATION_NORMAL);

                switch (orientation) {
                case ExifInterface.ORIENTATION_ROTATE_270:
                    rotate = 270;
                    break;
                case ExifInterface.ORIENTATION_ROTATE_180:
                    rotate = 180;
                    break;
                case ExifInterface.ORIENTATION_ROTATE_90:
                    rotate = 90;
                    break;
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
            Matrix matrix = new Matrix();
	matrix.postRotate(rotate);
	bitmap = Bitmap.createBitmap(bitmap , 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);

Another option is to rotate the bitmap in the result screen like this:

ImageView img=(ImageView)findViewById(R.id.ImageView01);
Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.refresh);
// Getting width & height of the given image.
int w = bmp.getWidth();
int h = bmp.getHeight();
// Setting post rotate to 90
Matrix mtx = new Matrix();
mtx.postRotate(90);
// Rotating Bitmap
Bitmap rotatedBMP = Bitmap.createBitmap(bmp, 0, 0, w, h, mtx, true);
BitmapDrawable bmd = new BitmapDrawable(rotatedBMP);

img.setImageDrawable(bmd);

I have also this type of same problem for some device:

private void rotateImage(final String path) {
	
	Bitmap scaledBitmap = Bitmap.createScaledBitmap(Conasants.bm1, 1000,
			700, true);
	Bitmap rotatedBitmap = null;
	try {
		ExifInterface ei = new ExifInterface(path);
		int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION,
				ExifInterface.ORIENTATION_NORMAL);
		Matrix matrix = new Matrix();
		switch (orientation) {
		case ExifInterface.ORIENTATION_ROTATE_90:
			matrix.postRotate(90);
			rotatedBitmap = Bitmap.createBitmap(scaledBitmap, 0, 0,
					scaledBitmap.getWidth(), scaledBitmap.getHeight(),
					matrix, true);
			break;
		case ExifInterface.ORIENTATION_ROTATE_180:
			matrix.postRotate(180);
			rotatedBitmap = Bitmap.createBitmap(scaledBitmap, 0, 0,
					scaledBitmap.getWidth(), scaledBitmap.getHeight(),
					matrix, true);
			break;
		case ExifInterface.ORIENTATION_ROTATE_270:
			matrix.postRotate(270);
			rotatedBitmap = Bitmap.createBitmap(scaledBitmap, 0, 0,
					scaledBitmap.getWidth(), scaledBitmap.getHeight(),
					matrix, true);
			break;
		default:
			rotatedBitmap = Bitmap.createBitmap(scaledBitmap, 0, 0,
					scaledBitmap.getWidth(), scaledBitmap.getHeight(),
					matrix, true);
			break;
		}
	} catch (Throwable e) {
		e.printStackTrace();
	}
	cropImage.setImageBitmap(rotatedBitmap);
	rotatedBitmap = null;
	Conasants.bm1 = null;
}

Try this way : static Uri image_uri; static Bitmap taken_image=null;

            image_uri=fileUri; // file where image has been saved

      taken_image=BitmapFactory.decodeFile(image_uri.getPath());
      try
        {
            ExifInterface exif = new ExifInterface(image_uri.getPath()); 
        
            int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);


            switch(orientation) {
                case ExifInterface.ORIENTATION_ROTATE_90:
                    taken_image=decodeScaledBitmapFromSdCard(image_uri.getPath(), 200, 200);
                    RotateBitmap(taken_image, 90);
                    break;
                case ExifInterface.ORIENTATION_ROTATE_180:
                    taken_image=decodeScaledBitmapFromSdCard(image_uri.getPath(), 200, 200);
                    RotateBitmap(taken_image, 180);

                    break;
                case ExifInterface.ORIENTATION_ROTATE_270:
                    taken_image=decodeScaledBitmapFromSdCard(image_uri.getPath(), 200, 200);
                    RotateBitmap(taken_image, 270);

                    break;
                case ExifInterface.ORIENTATION_NORMAL:
                    taken_image=decodeScaledBitmapFromSdCard(image_uri.getPath(), 200, 200);
                    RotateBitmap(taken_image, 0);

                    break;
            }

        }
        catch (OutOfMemoryError e)
        {
            Toast.makeText(getActivity(),e+"\"memory exception occured\"",Toast.LENGTH_LONG).show();


        }



public Bitmap RotateBitmap(Bitmap source, float angle) {
      Matrix matrix = new Matrix();
      matrix.postRotate(angle);

      round_Image = source;
      round_Image = Bitmap.createBitmap(source, 0, 0, source.getWidth(),   source.getHeight(), matrix, true);


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

}

No more checking the photo's exif data. Go easy with Glide.

Google introduced us an Image Loader Library for Android developed by bumptech named Glide as a library that recommended by Google. It has been used in many Google open source projects till now including Google I/O 2014 official application.

Ex : Glide.with(context).load(uri).into(imageview);

For more : https://github.com/bumptech/glide

public void setCameraPicOrientation(){
        int rotate = 0;
        try {

            ExifInterface exif = new ExifInterface(
                    imageFile.getAbsolutePath());
            int orientation = exif.getAttributeInt(
                    ExifInterface.TAG_ORIENTATION,
                    ExifInterface.ORIENTATION_NORMAL);

            switch (orientation) {
                case ExifInterface.ORIENTATION_ROTATE_270:
                    rotate = 270;

		/* Get the size of the image */
        BitmapFactory.Options bmOptions = new BitmapFactory.Options();

        BitmapFactory.decodeFile(mCurrentPhotoPath, bmOptions);
        int photoW = bmOptions.outWidth;

            scaleFactor = Math.min(photoW/targetW, photoH/targetH);
        }

		/* Set bitmap options to scale the image decode target */

Just encounter the same issue here, the code snippet below works for me:

private static final String[] CONTENT_ORIENTATION = new String[] {
        MediaStore.Images.ImageColumns.ORIENTATION
};

static int getExifOrientation(ContentResolver contentResolver, Uri uri) {
    Cursor cursor = null;

    try {
        cursor = contentResolver.query(uri, CONTENT_ORIENTATION, null, null, null);
        if (cursor == null || !cursor.moveToFirst()) {
            return 0;
        }
        return cursor.getInt(0);
    } catch (RuntimeException ignored) {
        // If the orientation column doesn't exist, assume no rotation.
        return 0;
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }
}

hope this does help :)

Try this in surfaceChanged callback:

    parameters.setRotation(90);
}else{
    parameters.setRotation(0);
}

Someone question about code, please tell me.

two One line solutions using Picasso and glide library

After spending a lot of time with a lot of solutions for image rotation problem I finally found two simple solutions. We don't need to do any additional works. Picasso and Glide are a very powerful library for handling images in your app includes. It will read image EXIF data and auto-rotates the images.

Using glide library https://github.com/bumptech/glide

Glide.with(this).load("http url or sdcard url").into(imgageView);

Using Picasso library https://github.com/square/picasso

Picasso.with(context).load("http url or sdcard url").into(imageView);
