Filter built-in gallery to show only pictures with GeoTag (Latitude and Longitude)

Question

Im doing an app that let the user pick an image from the built-in gallery.

so far so good.. The thig is,I need to show the user only photos which has GeoTags in it.

In other words, I need to filter the built-in gallery display to show only images which has Longitude and Latitude MetaData in them and NOT show all the other pictures in my phone

Here is a simple image picker code:

private void pickPlace()
{
    Intent in = new Intent(
    Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);      
    startActivityForResult(in, RESULT_LOAD_IMAGE);      
}

//We Get The Selected Image From Gallery And Display It To User..
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
     super.onActivityResult(requestCode, resultCode, data);

     try {
        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
             Uri selectedImage = data.getData();//URI for the picture
             String[] filePathColumn = { MediaStore.Images.Media.DATA };

             Cursor cursor = getContentResolver().query(selectedImage,
                     filePathColumn, null, null, null);
             cursor.moveToFirst();

             int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
             String picturePath = cursor.getString(columnIndex);
             cursor.close(); 

             //Load The Image Into Main Screen
             adjustImage(picturePath);

             //We get The Coordinates Back to 0
             mLongitude = (float) 0.0;
             mLatitude = (float) 0.0;
             mAddress = "";                              

         }
    } catch (NullPointerException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

This works good, Now I need to find how to filter and show only images with Latitude and Longitude.. and hide all the other images.

Thank You!

You can create an ExifInterface from the file name and then call getLatLong() for coordinate information. A simple IF condition can check if there is GeoLocation data in the file.
