I tried this code, and every time it force closes. The Uri object
gives me the Uri, but I can't see why it's failing... Please help!!!
Uri photoUri = intent.getData();
Cursor cursor = getContentResolver().query(photoUri, new String[]
{MediaStore.Images.ImageColumns.DATA}, null, null, null);
String absoluteFilePath = cursor.getString(0);
