Question

我收到以下错误：

W/DynamiteModule: Local module descriptor class for com.google.firebase.auth
not found

如果我决定在onCompleteListener内处理身份验证，我的代码可以正常运行，但是当我尝试从FirebaseAuth.AuthStateListener处理它时，我收到错误。

这是我的登录/注册活动：

public class MainActivity extends AppCompatActivity implements 
AdapterView.OnItemSelectedListener {

EditText number;
EditText ans;
TextView questionText;
Spinner country_code;
String[] codes;
String c_code;
Button next_button_1;
ArrayAdapter<String> adapter;
FirebaseAuth mAuth;
FirebaseAuth.AuthStateListener mAuthListener;

Random rand = new Random();

int a = rand.nextInt(10);
int b = rand.nextInt(10);
int c = a+b;

String tes;
String ran2;
String ran1;

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


    codes = new String[] {"+237","+233","+234"};
    number = (EditText) findViewById(R.id.editText1);
    ans = (EditText) findViewById(R.id.editText_question);
    questionText = (TextView) findViewById(R.id.questionText);


    ran1 = Integer.toString(a);
    ran2 = Integer.toString(b);
    tes = Integer.toString(c);
    questionText.setText( ran1 + " + " + ran2 + " = ");

    country_code = (Spinner) findViewById(R.id.spinner_country_codes);
    country_code.setOnItemSelectedListener(this);
    adapter = new ArrayAdapter<>(this,
            android.R.layout.simple_list_item_1,
            codes);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    country_code.setAdapter(adapter);

    next_button_1 = (Button) findViewById(R.id.sign_in_next_button);

    mAuth = FirebaseAuth.getInstance();
    mAuthListener = new FirebaseAuth.AuthStateListener() {

        @Override
        public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
            if (firebaseAuth.getCurrentUser() != null) {
                FirebaseUser user = firebaseAuth.getCurrentUser();
                String uid = user.getUid();
                Intent i = new Intent(MainActivity.this,Main2Activity.class);
                i.putExtra("uid", uid);
                i.putExtra("telephone", number.getText().toString());
                i.putExtra("country_code",c_code);
                startActivity(i);
            }
        }
    };

    if(next_button_1!=null){
        next_button_1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                /*
                Intent intent = new Intent(MainActivity.this, 
Main2Activity.class);
                startActivity(intent);
                */
                String answer = ans.getText().toString();
                if(answer.equals(tes)) {
                    String telphone_number = number.getText().toString();
                    if (TextUtils.isEmpty(c_code) || 
TextUtils.isEmpty(telphone_number)) {
                        Toast.makeText(MainActivity.this, "Empty field 
detected", Toast.LENGTH_SHORT).show();
                    } else {
                        String email = c_code + telphone_number + 
"mydomain.com";
                        String password = c_code + telphone_number;
                        startSignIn(email, password);
                    }
                }else {
                    a = rand.nextInt(10);
                    b = rand.nextInt(10);
                    c = a + b;

                    ran1 = Integer.toString(a);
                    ran2 = Integer.toString(b);
                    tes = Integer.toString(c);

                    questionText.setText( ran1 + " + " + ran2 + " = ");
                    Toast.makeText(MainActivity.this, "Your math test answer 
is wrong.", Toast.LENGTH_LONG).show();
                }
            }
        });
    }
}

@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, 
long id) {
    String c_code = codes[position].toString();
    this.c_code=c_code;
}

@Override

}



public void startSignIn(final String e,final String p) {
    //Toast.makeText(MainActivity.this, "email is "+ email +" and password 
is "+ password + "." , Toast.LENGTH_SHORT).show();
      mAuth.signInWithEmailAndPassword(e, p)
             .addOnCompleteListener(this, new OnCompleteListener<AuthResult>
() {
                 @Override
                 public void onComplete(@NonNull Task<AuthResult> task) {
                     if (!task.isSuccessful()) {
                         Toast.makeText(MainActivity.this, "Account not 
found.",
                                 Toast.LENGTH_SHORT).show();
                         Toast.makeText(MainActivity.this, "Creating a new

                                 Toast.LENGTH_LONG).show();
                         createAccont(e, p);
                     }
                 }
             });

    mAuth.createUserWithEmailAndPassword(e, p)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>

            });

}

我的build.gradle文件如下：

另外，我想告诉您，我的所有SDK库都是最新的，而且我的AVD上的Google Play服务也是最新的。

在我的MainActivity中，我首先尝试对用户进行身份验证，然后如果失败，我会尝试为您创建一个帐户。当我运行此代码并测试帐户创建过程（或登录过程）时，新帐户实际上是在我的Firebase控制台中创建的，但未通知AuthStateListener。

因此，我的第二个活动未启动，我的用户用户仍然在同一活动中，而不会导致应用崩溃。我还获得了Android Monitor上的日志：

W/DynamiteModule: Local module descriptor class for com.google.firebase.auth not found.

这只在今天开始。我已经在Firebase上进行了一段时间的身份验证，没有任何问题。我该怎么办？

Answer 1

我遇到了同样的问题，谷歌搜索了一下我认为在gradle上的maven存储库并将其添加到项目级别gradle

allprojects {
    repositories {
        // ...
        maven { url 'https://maven.fabric.io/public' }
    } }

这可以解决问题

Firebase AuthListener无法正常工作
