Question

我为我的用户开设了一个名为“User”的课程。所有的 getter 和 setter 都是正确的。我在主要活动中初始化了“mUser”以供应用程序全局使用（MainActivity.mUser）。

Log.i("..............UID Used", auth.getCurrentUser().getUid()); 为用户返回正确的 Uid。

我正在努力解决的是在 try/catch 块中没有执行任何操作。目录中没有记录任何内容，应用程序崩溃。它不会转到 onComplete、onFail，也不会捕获异常。应用程序只是转到下一部分代码，该部分引用从该块中提取的数据，并由于 mUser 的值全部为空而给出错误。

它正在工作，然后突然停止，我不确定为什么。任何人都可以对此有所了解吗？

private void getUserProfileInfo() {
    MainActivity.mUser.clearUser();
    FirebaseAuth auth = FirebaseAuth.getInstance();
    Log.i("..............UID Used", auth.getCurrentUser().getUid());
    FirebaseDatabase firebaseDatabase = FirebaseDatabase
            .getInstance("https://godsvong-default-rtdb.firebaseio.com/");
    DatabaseReference databaseReference = firebaseDatabase.getReference();
    try {
        databaseReference.child("User_Profiles").child(auth.getCurrentUser().getUid())
                .get().addOnCompleteListener(new OnCompleteListener<DataSnapshot>() {
            @Override
            public void onComplete(@NonNull Task<DataSnapshot> task) {
                MainActivity.mUser = task.getResult().getValue(User.class);
                Log.i("Get Data", "SUCCESS!!!!!");
                MainActivity.mUser.showUserDataInCatlog();
            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Log.i("Get Data", "FAILED!!!!!");
            }
        });
    }
    catch (Exception e){
        Log.i(".............ERROR", e.toString());
    }

    String path = MainActivity.mUser.getmProfilePicUrl();
    //MainActivity.mUser.showUserDataInCatlog();
    //Log.i(".............PATH", MainActivity.mUser.getmProfilePicUrl());
    //Log.i(".............PATH", path);

    StorageReference gsReference = FirebaseStorage.getInstance()
            .getReferenceFromUrl(path);

无法再从 Firebase 数据库获取数据？
