I get following error frequently when I try to sign in silently on android. How can I debug this. What is the reason for this. (I have an active google account on my android phone.)

signInSilently(): failure
com.google.android.gms.common.api.ApiException: 4: 
at com.google.android.gms.common.internal.zzb.zzz(Unknown Source)
at com.google.android.gms.common.internal.zzbk.zzaa(Unknown Source)
at com.google.android.gms.common.internal.zzbl.zzs(Unknown Source)
at com.google.android.gms.common.api.internal.zzs.zzc(Unknown Source)
at com.google.android.gms.common.api.internal.zzs.setResult(Unknown Source)
at com.google.android.gms.auth.api.signin.internal.zzg.zza(Unknown Source)
at com.google.android.gms.auth.api.signin.internal.zzt.onTransact(Unknown Source)
at android.os.Binder.execTransact(Binder.java:446)

the code is follows 

 mGoogleSignInClient.silentSignIn().addOnCompleteListener(activity,
     new OnCompleteListener<GoogleSignInAccount>() {
        @Override
        public void onComplete(@NonNull Task<GoogleSignInAccount> task) {
             if (task.isSuccessful()) {
                   Log.d(TAG, "signInSilently(): success");
                   onConnected(task.getResult());
             } else {
               Log.d(TAG, "signInSilently(): failure", task.getException());
                        Toast.makeText(activity, "A sign-in problem encountered.",
                                Toast.LENGTH_SHORT).show();
                        onDisconnected();
             }
          }
       });

There is a list of error codes

According to it, your error code means following:

public static final int SIGN_IN_REQUIRED
The client attempted to connect to the service but the user is not signed in. The client may choose to continue without using the API. Alternately, if hasResolution() returns true the client may call startResolutionForResult(Activity, int) to prompt the user to sign in. After the sign in activity returns with RESULT_OK further attempts should succeed.

Constant Value: 4

It means, that user needs to login manually before you can use silentSignIn. You can find an example on Google github

That error happened to me because I haven't added the email I was testing with to the Testers tab in Google Play Games Console.

I believe it also occurs if your build hasn't been signed with the same SHA1 key that your google play games app id was generated with
