How to Select and Load saved game snapshot from google play games

Question

I am on the Saved Games screen where is shows the list of all saves. When I select a saved game the app crashes with the error: android.os.BadParcelableException: ClassNotFoundException when unmarshalling: com.google.android.gms.games.snapshot.SnapshotMetadataEntity

It's basically the same code from here https://developers.google.com/games/services/android/savedgames?authuser=3&hl=sl

Please assist.

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent intent) {
        super.onActivityResult(requestCode, resultCode, intent);

        switch (requestCode) {
            case RC_LIST_SAVED_GAMES:
                if (resultCode == RESULT_OK) {
                    if (intent != null) {
                        if (intent.hasExtra(SnapshotsClient.EXTRA_SNAPSHOT_METADATA)) {
                            // Error occurs here when saved game is selected
                            SnapshotMetadata snapshotMetadata = intent.getParcelableExtra(SnapshotsClient.EXTRA_SNAPSHOT_METADATA);
                            assert snapshotMetadata != null;
                            sCurrentSaveName = snapshotMetadata.getUniqueName();
                            onLoadFromSnapshot(intent.getParcelableExtra(SnapshotsClient.EXTRA_SNAPSHOT_METADATA));
                        } else if (intent.hasExtra(SnapshotsClient.EXTRA_SNAPSHOT_NEW)) {
                            String unique = Long.toString(System.currentTimeMillis());
                            sCurrentSaveName = "snapshotH-" + unique;
                            onSaveSnapshot(null);
                        }
                    }
                }
                break;
        }
    }

This is what is shown in Logcat

In my case, it is not working only in my release build since it is using pro guard. I solved it by adding pro guard configuration described here
