android - GoogleApiClient.isConnected() return always false

Question

I'm trying to implement leaderboard in my game. I wrote this code:

GoogleApiClient mGoogleApiClient;
mGoogleApiClient = new GoogleApiClient.Builder(this)
    .addApi(Drive.API)
    .addScope(Drive.SCOPE_FILE)
    .build();

mGoogleApiClient.connect();
//....

while(!mGoogleApiClient.isConnected())Log.d("","NO CONNECTED");
Games.Leaderboards.submitScore(mGoogleApiClient, "MY_LEADERBOARD_ID",newscore);

Why mGoogleApiClient.isConnected() returns always false?

EDIT1: Ok, now it works (I have changed Drive.API with Games.API and Drive.SCOPE_FILE with Games.SCOPE_GAME) but when I call submitScore() even if it's all ok in the Log, the leaderboard is still empty. How can I check if submitScore() really works?

EDIT2: I used

startActivityForResult(Games.Leaderboards.getLeaderboardIntent(mGoogleApiClient, "MY_LEADERBOARD_ID"), REQ_LEADERBOARD);

and everything works!

Answer 1

You need to add a couple callback listeners to the Builder (or GoogleApiClient). What's most likely happening is that the login is failing because you don't have permissions yet. You need to handle that failure so that the user can authorize your app.
