我正在发布并检索需要Firebase身份验证的应用程序。我知道Firebase使用异步方法，以免在主线程上传递其功能。但是，除了FirebaseAuthentication和FireDatabase.getInstance().getReference().child()之外，其他所有东西似乎都在起作用。这造成很多困难。
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，为您提供登录或注册按钮。在这种情况下，请注册:
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，该页面不起作用，因为
FirebaseAuthentication和FireDatabaseReference().getInstance().getReference().child()不断使我的应用加载并崩溃。 package com.gmail.peeman34.eglisaofficial;

在某种程度上，这是我的堆栈跟踪。只需忘记处理程序即可。我担心Firebase实例。处理程序工作正常。由于我一直在尝试和尝试错误，因此它们安排有误。

最佳答案
找出问题所在，在gradle文件中，无论存储，数据库还是身份验证，我都没有firebaseui。我也意识到，firebase依赖关系，firebaseui和play服务之间存在兼容性问题。也许这可以帮助https://github.com/firebase/FirebaseUI-Android
关于android - FirebaseAuthentication.getInstance()导致应用崩溃，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/43701781/
