[android help] Getting Image path from URI not working for Picasa folder

Getting Image path from URI not working for Picasa folder

Cursor cursor = contentResolver.query(uri, null, null, null, null);
cursor.moveToFirst();
String filePath = cursor.getString(cursor.getColumnIndexOrThrow(MediaColumns.DATA));

Unlike other folders like Camera, Screenshots, Foursquare etc.., The Pictures from Picasa folder have less no.of columns, of which _data is not there

and Hence I get the Exception:

java.lang.IllegalArgumentException: column'_data' does not exist

There is a column named picasa_id and a Constant in android:

MediaStore.Images.Media.PICASA_ID

Will that help in getting the correct image path?

Also if I had to download the image from the folder and save in my-app-images folder and then get the actual path. How will I even know that the image URI is from Picasa?
