android - Can't connect to Google Games API with 11.0.2 Play Services -

i know stackoverflow has lot of questions regarding issue 1 related recent changes in games development. first of there no strict guide integrating games api. @ least didnt find fresh. 1 guide simple sign in , basegameutils not suitable new changes anymore. tried - doesn't work. perhaps faced issue.

i able connect client mapiclient.hasconnectedapi(games.api) stull returns false on onconnected method.

i've added sha-1 keys both release , debug versions , in google console see auto-generated ids web , android clients. last 1 added string server_client_id. i've downloaded google-services.json file. yeah, , manifest has meta-data:

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

my current code:

oncreate():

    googlesigninoptions gso = new googlesigninoptions.builder(googlesigninoptions.default_games_sign_in)             //.requestserverauthcode(getstring(r.string.server_client_id))             //.requestscopes(new scope(scopes.games), new scope(scopes.profile))             .build();      mapiclient = new googleapiclient.builder(this)             .addapi(games.api)             .addapi(auth.google_sign_in_api, gso)             //.addscope(games.scope_games)             .addconnectioncallbacks(this)             .addonconnectionfailedlistener(this)             .build(); 

onstart():

mapiclient.connect(googleapiclient.sign_in_mode_optional); 

onconnected():

 if (mapiclient.hasconnectedapi(games.api)) { //always returns false         auth.googlesigninapi.silentsignin(mapiclient).setresultcallback(new resultcallback<googlesigninresult>() {             @override             public void onresult(@nonnull googlesigninresult googlesigninresult) {                 // in case, sure result success.                 googlesigninaccount acct = googlesigninresult.getsigninaccount();              }         });     }  

also tried this guide didn't work. couldn't sign in , resolveissue called time. guess it's obsolete.

could suggest fresh solution tested working?
