java - 加载时出现对话框 "keep' s 后无法进入第二个 Activity ”

Question

在我的主要 Activity 上出现“继续加载”对话框后，无法进入第二个 Activity ，并且可以加载几个小时而不会出现错误我使用 facebook acount 套件，我没有看到错误，这里是主要 Activity 源代码主要 Activity java:

公共(public)类 MainActivity 扩展 AppCompatActivity {

private static final int REQUEST_CODE = 1000;
Button btnContinue;

    super.attachBaseContext(CalligraphyContextWrapper.wrap(newBase));
}

@Override

    super.onCreate(savedInstanceState);

            .build());
    setContentView(R.layout.activity_main);


    printKeyHash();

    //Init Firebase
    auth = FirebaseAuth.getInstance();
    db = FirebaseDatabase.getInstance();
    users = db.getReference(Common.user_driver_tbl);

    //init view
    btnContinue = (Button)findViewById(R.id.btnContinue);

    rootLayout =(RelativeLayout)findViewById(R.id.rootLayout);


    //Event
    btnContinue.setOnClickListener(new View.OnClickListener() {
        @Override

如果需要更多!或者是否还缺少一些东西，我在 Android 编程方面还是个新手，所以......

尝试使用 onCancel 和 onError 方法中的关闭对话框并打印错误来判断。
