How to get file name from file path in android
AndroidAndroid CameraAndroid SdcardAndroid Problem Overview
I want to get file name from sdcard file path.
e.g. :/storage/sdcard0/DCIM/Camera/1414240995236.jpg I want get 1414240995236.jpg
I have written the code to fetch the same but it is not working. Please help.
Below is my code:
@Override
protected void onActivityResult( int requestCode, int resultCode, Intent data)
{
if ( requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if ( resultCode == RESULT_OK) {
/*********** Load Captured Image And Data Start ****************/
String imageId = convertImageUriToFile( imageUri,CameraActivity);
// Create and excecute AsyncTask to load capture image
new LoadImagesFromSDCard().execute(""+imageId);
/*********** Load Captured Image And Data End ****************/
} else if ( resultCode == RESULT_CANCELED) {
Toast.makeText(this, " Picture was not taken ", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, " Picture was not taken ", Toast.LENGTH_SHORT).show();
}
}
}
/************ Convert Image Uri path to physical path **************/
public static String convertImageUriToFile ( Uri imageUri, Activity activity ) {
Cursor cursor = null;
int imageID = 0;
try {
/*********** Which columns values want to get *******/
String [] proj={
MediaStore.Images.Media.DATA,
MediaStore.Images.Media._ID,
MediaStore.Images.Thumbnails._ID,
MediaStore.Images.ImageColumns.ORIENTATION
};
cursor = activity.managedQuery(
imageUri, // Get data for specific image URI
proj, // Which columns to return
null, // WHERE clause; which rows to return (all rows)
null, // WHERE clause selection arguments (none)
null // Order-by clause (ascending by name)
);
// Get Query Data
int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID);
int columnIndexThumb = cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);
int file_ColumnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
//int orientation_ColumnIndex = cursor.
// getColumnIndexOrThrow(MediaStore.Images.ImageColumns.ORIENTATION);
int size = cursor.getCount();
/******* If size is 0, there are no images on the SD Card. *****/
if (size == 0) {
imageDetails.setText("No Image");
}
else
{
int thumbID = 0;
if (cursor.moveToFirst()) {
/**************** Captured image details ************/
/***** Used to show image on view in LoadImagesFromSDCard class ******/
imageID = cursor.getInt(columnIndex);
thumbID = cursor.getInt(columnIndexThumb);
String Path = cursor.getString(file_ColumnIndex);
//String orientation = cursor.getString(orientation_ColumnIndex);
String CapturedImageDetails = " CapturedImageDetails : \n\n"
+" ImageID :"+imageID+"\n"
+" ThumbID :"+thumbID+"\n"
+" Path :"+Path+"\n";
full_path_name=Path;
//this is my path
//Path :/storage/sdcard0/DCIM/Camera/1414240995236.jpg i want get 1414240995236.jpg
// Show Captured Image detail on activity
imageDetails.setText(Path);
}
}
} finally {
if (cursor != null) {
cursor.close();
}
}
// Return Captured Image ImageID ( By this ImageID Image will load from sdcard )
return ""+imageID;
}

Solution 1 - Android
I think you can use substring method to get name of the file from the path string.
String path=":/storage/sdcard0/DCIM/Camera/1414240995236.jpg";
// it contains your image path...I'm using a temp string...
String filename=path.substring(path.lastIndexOf("/")+1);
Solution 2 - Android
Simple and easy way to get File name
File file = new File("/storage/sdcard0/DCIM/Camera/1414240995236.jpg");
String strFileName = file.getName();
After add this code and print strFileName you will get strFileName = 1414240995236.jpg
Solution 3 - Android
The easiest solution is to use Uri.getLastPathSegment():
String filename = uri.getLastPathSegment();
Solution 4 - Android
FilenameUtils to the rescue:
String filename = FilenameUtils.getName("/storage/sdcard0/DCIM/Camera/1414240995236.jpg");
Solution 5 - Android
We can find file name below code:
File file =new File(Path);
String filename=file.getName();
Solution 6 - Android
Final working solution:
public static String getFileName(Uri uri) {
try {
String path = uri.getLastPathSegment();
return path != null ? path.substring(path.lastIndexOf("/") + 1) : "unknown";
} catch (Exception e) {
e.printStackTrace();
}
return "unknown";
}
Solution 7 - Android
Old thread but thought I would update;
File theFile = .......
String theName = theFile.getName(); // Get the file name
String thePath = theFile.getAbsolutePath(); // Get the full
More info can be found here; Android File Class

One liner solution in kotlin assuming you have the absolute path
File(currentPhotoPath).name
Solution 9 - Android
you can use the Common IO library which can get you the Base name of your file and the Extension.
String fileUrl=":/storage/sdcard0/DCIM/Camera/1414240995236.jpg";
String fileName=FilenameUtils.getBaseName(fileUrl);
String fileExtention=FilenameUtils.getExtension(fileUrl);
//this will return filename:1414240995236 and fileExtention:jpg
Solution 10 - Android
Other Way is:
String[] parts = selectedFilePath.split("/");
final String fileName = parts[parts.length-1];
Solution 11 - Android
add this library
implementation group: 'commons-io', name: 'commons-io', version: '2.6'
then call FilenameUtils class
val getFileName = FilenameUtils.getName("Your File path")
Solution 12 - Android
In kotlin:
fileUrl.split("/").last()
