Google Play Services Leak

Question

I started using Google Play Game Services a while ago, and yesterday while checking the logcat I couldnt help to notice this error:

E/DataBuffer(3183)

Answer 1

These items extend DataBuffer: AchievementBuffer, AppStateBuffer, FilteredDataBuffer, GameBuffer, InvitationBuffer, LeaderboardBuffer, LeaderboardScoreBuffer, MetadataBuffer, MomentBuffer, ParticipantBuffer, PersonBuffer, PlayerBuffer, TurnBasedMatchBuffer.

These are generally found in your listeners of those particular items. For example:

public void onTurnBasedMatchesLoaded(int statusCode, LoadMatchesResponse response) 
{
    TurnBasedMatchBuffer buff = response.getMyTurnMatches();
    // do some stuff with buff
    buff.close()
}

public void onPlayersLoaded(int statusCode, PlayerBuffer buff) 
{
    Player p = buff.get(0);
    buff.close();
}

The error doesn't report until after I exit my app and re-enter. If I call up my matches 3 times and exit the app without calling buff.close(), I can expect to see the warning 3 times upon opening it back up again. Add in the buff.close() and they disappear. Voila!

Any SubClass of Data Buffer needs to be released. So after you are done with that object release it.

Data Buffer object contains a release() method so after you are done with that object just release it using databuffer.release();.
