Get file path of image on Android

Question

I have an app that can make pictures and upload them. The upload requires the file path of the photo but I can't get it.

This is my code:

public void maakfoto (View v) {

    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
    startActivityForResult(cameraIntent, CAMERA_REQUEST);

}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {  

        Bitmap photo = (Bitmap) data.getExtras().get("data"); 
        imageView.setImageBitmap(photo);
        knop.setVisibility(Button.VISIBLE);
        System.out.println(mImageCaptureUri);
    }  
}

Please help me to get the file path.

Posting to Twitter needs the image's actual path on the device to be sent in the request to post. I was finding it mighty difficult to get the actual path and more often than not I would get the wrong path.

To counter that, once you have a Bitmap, I use that to get the URI from using the getImageUri(). Subsequently, I use the tempUri Uri instance to get the actual path as it is on the device.

This is production code and naturally tested. ;-)

protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
        Bitmap photo = (Bitmap) data.getExtras().get("data"); 
        imageView.setImageBitmap(photo);
        knop.setVisibility(Button.VISIBLE);


        // CALL THIS METHOD TO GET THE URI FROM THE BITMAP
        Uri tempUri = getImageUri(getApplicationContext(), photo);

        // CALL THIS METHOD TO GET THE ACTUAL PATH
        File finalFile = new File(getRealPathFromURI(tempUri));

        System.out.println(mImageCaptureUri);
    }  
}

public Uri getImageUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
    return Uri.parse(path);
}

public String getRealPathFromURI(Uri uri) {
    Cursor cursor = getContentResolver().query(uri, null, null, null, null); 
    cursor.moveToFirst(); 
    int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA); 
    return cursor.getString(idx); 
}
