api - Android GoogleApiClient: Can't connect -

i'm trying implement new googleapiclient android application, googleapiclient can't connect. use connect() method, isconnecting() method returns true , isconnected() never true.

my code

init

mgoogleapiclient = new googleapiclient.builder(this)                 .addapi(games.api).addscope(games.scope_games)                 .addconnectioncallbacks(this)                 .addonconnectionfailedlistener(this)                 .build(); 

connect

@override protected void onstart() {     super.onstart();     if( mgoogleapiclient != null )         mgoogleapiclient.connect() } 

open leaderboard

private void openachievements() {   if( !mgoogleapiclient.isconnected() ) // false       return;    startactivityforresult(games.achievements.getachievementsintent(mgoogleapiclient), request_achievements); } 

implements:

@override public void onconnected(bundle bundle) {     log.e("debug", "connected!"); }  @override public void onconnectionsuspended(int i) {     log.e("debug", "connection suspended"); }  @override public void onconnectionfailed(connectionresult connectionresult) {     log.e("debug", "connection failed"); } 

permissions:

<uses-permission android:name="android.permission.internet"/> <uses-permission android:name="android.permission.access_network_state"/> 

meta-data:

<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> <meta-data android:name="com.google.android.gms.games.app_id" android:value="@string/app_id" /> 

can help?

when you're building api client you're adding connection callbacks , in case it's activity implementing these callbacks.

and 1 of methods activity should implement onconnected() called when connection established. need call openachievements() method. , can remove unnecessary check !mgoogleapiclient.isconnected()
