getLatLong always returns false

I'm trying to retrieve longitude and latitude values from geotagged images using android.media.ExifInterface library. However, getLatLong always returns false although the image is geotagged. This is my code :

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Button galleryButton = (Button) findViewById(R.id.galleryButton);

    galleryButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
           Intent pickPhoto = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(pickPhoto , 1);


        }

    });


}


protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {

    super.onActivityResult(requestCode, resultCode, imageReturnedIntent);

    switch(requestCode) {
        case 0:
            if(resultCode == RESULT_OK){
                Uri selectedImage = imageReturnedIntent.getData();
                ExifInterface exif = new ExInterface(selectedImage.getPath());
                float[] latlong = null;
                bool result = exif.getLatLong(latlong);


            }

            break;

    }
}

As you can see, I'm initializing exif object with the path from returned URI and it contains path like "/external/images/media/2330". When I call getLatLong, it always returns false. I have also tried the example from this page, but still does not work. Any help would be appreciated.

getPath() only works on a Uri with a file scheme. Yours has a content scheme. Plus, you are using the ExifInterface with the security flaws.

Add the com.android.support:exifinterface:25.3.1 library to your dependencies.

Next, replace your android.media.ExifInterface import with one for android.support.media.ExifInterface.

Then, replace:

ExifInterface exif = new ExInterface(selectedImage.getPath());

with:

ExifInterface exif = new ExifInterface(getContentResolver().openInputStream(selectedImage));
