android - GoogleSignInClient.signOut 崩溃并显示 : "Call connect() and wait for onConnected() to be called"

Question

• Google Play 服务版本 11.6.2
• 目标 Android SDK 27

我已通过引用 Google 在以下存储库中提供的 TypeANumber 项目实现了建议的新 GoogleSignIn 流程:

https://github.com/playgameservices/android-basic-samples/blob/master/TypeANumber/src/main/java/com/google/example/games/tanc/MainActivity.java

崩溃场景:

• 用户通过身份验证并成功登录。
• 应用暂停和恢复。
• 用户尝试通过调用下面的注销方法从 Google 注销。

这是我的初始化代码:

public void initialize(Activity activity, View viewForGamePopups) {
    this.activity = activity;
    this.viewForGamePopups = viewForGamePopups;
    GoogleSignInOptions googleSignInOptions = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN).
            requestServerAuthCode(backendClientId).
            requestProfile().
            build();
    googleSignInClient = GoogleSignIn.getClient(activity, googleSignInOptions);
}

登录:

public void signIn() {
    activity.runOnUiThread(new Runnable() {
        @Override
        public void run() {
            if(isSignedIn()) {
                silentSignIn();
            } else {
                activity.startActivityForResult(googleSignInClient.getSignInIntent(), RC_SIGN_IN);
            }
        }
    });
}

public boolean isSignedIn() {
    return GoogleSignIn.getLastSignedInAccount(activity) != null;
}

public void onActivityResult(int requestCode, int responseCode, Intent intent) {
    if (requestCode == RC_SIGN_IN) {
        try {
            Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(intent);
            GoogleSignInAccount account = task.getResult(ApiException.class);
            setViewForGamePopups(account);
            onConnected(account);
        } catch (ApiException apiException) {
            String message = apiException.getMessage();
            if (message == null || message.isEmpty()) {
                message = "Unexpected error!";
            }
            onDisconnected();
        }
    }
}

private void silentSignIn() {
    googleSignInClient.silentSignIn().addOnCompleteListener(activity,
        new OnCompleteListener<GoogleSignInAccount>() {
            @Override
            public void onComplete(@NonNull Task<GoogleSignInAccount> task) {
                if (task.isSuccessful()) {
                    GoogleSignInAccount googleSignInAccount = task.getResult();
                    setViewForGamePopups(googleSignInAccount);
                } else {
                    signOut();
                }
            }
        }
    );
}

唱出来:

public void signOut() {
    activity.runOnUiThread(new Runnable() {
        @Override
        public void run() {
            if (!isSignedIn()) {
                return;
            }
            googleSignInClient.signOut().addOnCompleteListener(activity,
                new OnCompleteListener<Void>() {
                    @Override
                    public void onComplete(@NonNull Task<Void> task) {
                        ...
                    }
                }
            );
        }
    });
}

以下堆栈跟踪发生崩溃:

Fatal Exception: java.lang.IllegalStateException: Not connected. Call connect() and wait for onConnected() to be called. at com.google.android.gms.common.internal.zzd.zzaka(Unknown Source:10) at com.google.android.gms.common.internal.zzd.zzakb(Unknown Source:17) at com.google.android.gms.games.internal.GamesClientImpl.zzg(Unknown Source:5) at com.google.android.gms.games.internal.GamesClientImpl.zza(Unknown Source:5) at com.google.android.gms.common.api.internal.zzbr.signOut(Unknown Source:77) at com.google.android.gms.common.api.internal.zzbp.zzaih(Unknown Source:26) at com.google.android.gms.common.api.internal.zzbp.handleMessage(Unknown Source:507) at android.os.Handler.dispatchMessage(Handler.java:101) at android.os.Looper.loop(Looper.java:164) at android.os.HandlerThread.run(HandlerThread.java:65)

我已按照 TypeANumber 示例中的建议为 onResume 案例添加静默登录。

public void onResume() {
    logD("Silent sign in onResume called!");
    googleSignInClient.silentSignIn().addOnCompleteListener(new OnCompleteListener<GoogleSignInAccount>() {
        @Override
        public void onComplete(@NonNull Task<GoogleSignInAccount> task) {
            if(task.isComplete()) {
                logD("Google Connection completed!");
            }
            if(task.isSuccessful()) {
                logD("Google Connection success!");
            } else {
                logD("Google Connection failed!");
            }
        }
    });
    logD("Silent sign in onResume ended!");
}

即使我在静默登录完成后按下退出按钮 (onResume)，我仍然遇到此崩溃。

这个问题有解决办法吗？

正如我在博文中所说，在 Activity 的“onResume”回调中调用 silentSignIn 无助于修复 Google Play 服务版本 11.6.2 的崩溃。将Google Play服务版本升级到12.0.1后，无法再次重现崩溃。即使在“onResume”方法中删除 silentSignIn 调用后，应用程序也不再崩溃。
