You don't have control over the data returned by the Gallery Activity, it's just return its own result intent, so your intent extra is lost. You should use an alternative way to get the value, maybe you can use something like this:

final int yourReturnCode = 3040;
final int yourExampleValue = 40;

 Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); ((Activity) _ctx).startActivityForResult( Intent.createChooser(intent, "Select Picture"), yourReturnCode); protected void onActivityResult(int requestCode, int resultCode, Intent data) { int yourValue = 0; if (resultCode == yourReturnCode) { yourValue = yourExampleValue; } }
