java - 第 3 次重新启动后，使用 Firebase 和 Facebook 身份验证的 LoginActivity 没有响应

Question

每次在第 3 次重新启动时，我的应用程序都会卡在黑屏上。我不知道为什么，我查看了 Facebook 和 Firebase 文档，并遵循示例 ( github )。有没有人也遇到过这种情况？

附加信息:

Facebook 库:com.facebook.android:facebook-android-sdk:4.12.0

Firebase 库:com.google.firebase:firebase-auth:9.0.0

主 Activity

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        navigationIntent = new Intent(this, NavigationActivity.class);
        serviceIntent = new Intent(this, BackgroundService.class);

        // Initialize Firebase
        firebaseAuth = FirebaseAuth.getInstance();

        firebaseAuthListener = new FirebaseAuth.AuthStateListener() {
            @Override
            public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
                FirebaseUser user = firebaseAuth.getCurrentUser();

                if (user != null) {
                    // User is signed in
                    // if so start next activty and close this one

                }

            }
        });


    }

    }

Answer 1

这可能是后台 Firebase 崩溃进程以 SDK 未预期的方式调用 Facebook SDK 的问题。您可以通过检查 Firebase 是否已正确初始化来保护它:

@Override
public void onCreate() {
    super.onCreate();
    if (!FirebaseApp.getApps(this).isEmpty()) {
      FacebookSdk.sdkInitialize(getApplicationContext());
    }
}

尝试一下，看看它是否能阻止卡住的发生。
