firestore crash runtimeException 试图获取集合

Question

我正在尝试从 firestore 获取集合。我收到以下错误。

java.lang.RuntimeException: Internal error in Firestore (0.6.6-dev).

和代码

private FirebaseAuth mAuth;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        mAuth = FirebaseAuth.getInstance();


        mAuth.signInWithEmailAndPassword("username","password").addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
            @Override
            public void onComplete(@NonNull Task<AuthResult> task) {

                FirebaseFirestore db = FirebaseFirestore.getInstance();
                db.collection("mycollection").get().addOnCompleteListener(new OnCompleteListener<QuerySnapshot>() {
                    @Override
                    public void onComplete(@NonNull Task<QuerySnapshot> task) {

                    }
                }).addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {

                    }
                });

            }
        });

firebase 身份验证工作正常，但当我尝试获取集合时代码崩溃，如下所示。有时代码工作正常并调用 onComplete

db.collection("mycollection").get().addOnCompleteListener

首先，尝试清除设备上应用程序管理器中的数据，然后再次运行该应用程序。如果它不能以这种方式工作，请尝试将以下代码行添加到 progauard 规则：

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}
