java用户无法注销firebase 安卓

Question

用户无法注销Firebase 安卓。当我按下注销按钮时，它不会注销

代码如下：-

btnLogout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            logOut();



        }
    });

private void logOut() {

    FirebaseAuth.getInstance().signOut();

}

日志包括：

在该方法中：

private void logOut() {
FirebaseAuth.getInstance().signOut();
Intent i=new Intent(getApplicationContext(),LoginActivity.class);
startActivity(i);

}

在上面的例子中，用户将被注销，然后他将进入LoginActivity

然后在您的LoginActivity中，您可以检查是否有用户登录或没有登录。请尝试以下操作：

 FirebaseUser user=FirebaseAuth.getInstance().getCurrentUser();

 if(user!=null){

  Log.i("a user is logged in: ",user);
 }
  else{
       Log.i("Username", "there is no user");
     }
