android - FirebaseAuthentication.getInstance() 导致应用程序崩溃

Question

我正在制作一个需要 Firebase 身份验证的发布和检索应用。我知道 Firebase 使用异步方法，以免在主线程上传递其函数。然而，除了 FirebaseAuthentication 和 FireDatabase.getInstance().getReference().child() 之外，一切似乎都正常工作。这造成了很多困难。

我的启动器页面 Activity ..

 package com.gmail.peeman34.eglisaofficial;


//private Button eglisasignupbutton;
//Handler handler = null;

public EGLISA_OFFICIAL() {
    super();
  }
//}

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.eglisa_official);


    Thread timer = new Thread() {

        @Override
        public void run() {

            try {
                sleep(5000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

            Intent openStartingPoint = new Intent(EGLISA_OFFICIAL.this, BRIDGE.class);
            startActivity(openStartingPoint);
            finish();

        }
    };
    timer.start();
 }

 }

这是我的页面，为您提供是否登录或注册的按钮。在这种情况下注册:

package com.gmail.peeman34.eglisaofficial;

public class BRIDGE extends AppCompatActivity {
private Button signituphere;
private Button signitinhere;
Handler firsthandler = new Handler();
Thread mythread;
Handler handler;
Intent peethread;
public BRIDGE() {
    super();
  } 

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.bridge);


    signituphere = (Button) findViewById(R.id.signituphere);


    Button signitinhere = (Button) findViewById(R.id.signituphere);

        Thread mythread = new Thread(new Mythread());
      mythread.start();


   }

public void startLogin(View view){
       handler = new Handler();
    handler.post(new Runnable() {
        @Override
        public void run() {
             peethread = new Intent(BRIDGE.this, ActivityMaiin.class);

            startActivity(peethread);

        }
     });


    }


class Mythread extends Thread {


    private Handler handler;

    public Mythread() {

     }

    @Override
    public void run() {


        try {


            sleep(10000);

            Looper.prepare();
            handler = new Handler();
            Looper.loop();


        } catch (InterruptedException e) {
            e.printStackTrace();
        }




    }



    }

    }

这是注册页面无法正常工作，因为 FirebaseAuthentication 和 FireDatabaseReference().getInstance().getReference().child() 不断使我的应用程序加载并崩溃。

这是我的堆栈跟踪，在某种程度上非常明显。忘记处理程序吧。我担心 Firebase 实例。处理程序工作得很好。由于我一直在尝试和犯错，它们的排列有点困惑。

Answer 1

找出问题所在，在我的 gradle 文件中，无论是用于存储、数据库还是身份验证，我都没有 firebaseui。我还意识到 firebase 依赖项、firebaseui 和 play 服务之间存在兼容性问题。也许这可能有帮助https://github.com/firebase/FirebaseUI-Android
