  W / DynamiteModule：com.google.firebase.auth的本地模块描述符类
未找到

如果我决定处理 onCompleteListener ，但是当我尝试从 FirebaseAuth.AuthStateListener 处理它时，出现一个错误。



这里是我的签名/注册Activity： 

  public class MainActivity extends AppCompatActivity implements 
 AdapterView .OnItemSelectedListener {
 
 EditText编号; 
 EditText ans; 
 TextView questionText; 
 Spinner country_code; 
 String []代码; 
字符串c_code; 
按钮next_button_1; 
 ArrayAdapter< String>适配器; 
 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; 
字符串ran2; 
字符串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）;

 country_code.setAdapter（adapter）; 
 
 next_button_1 =（Button）findViewById（R.id.sign_in_next_button）; 
 
 mAuth = FirebaseAuth.getInstance（）; 
 mAuthListener = new FirebaseAuth.AuthStateListener（）{
 $ b @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（）{

 Toast.makeText（MainActivity.this，Empty field

 $ else $ {
 String email = c_code + telphone_number + 
mydomain.com; 
 String password = c_code + telphone_number; 
 startSignIn（电子邮件，密码）; 
} 
} else {

 ran1 = Integer.toString（a）;

 questionText.setText（ran1 +++ ran2 +=）; 
 Toast.makeText（MainActivity.this，您的数学测试答案

} 
} 
}）; 
 
 
 $ b @Override 
 public void onItemSelected（AdapterView<> parent，View view，int position，
 long id）{
 String c_code = codes [position] .toString（）; 
 this.c_code = c_code; 
 
 $ b @Override 
 public void onNothingSelected（AdapterView<> parent）{
} 
 
 
 
 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>任务）{
 if（！task.isSuccessful（））{

 found。，
 Toast.LENGTH_SHORT ）.show（）;

 if（！task.isSuccessful（））{
 Toast。 makeText（MainActivity.this，Authentication 
 Failed，
 Toast.LENGTH_SHORT）.show（）; 
} 
} 
}）; 
} 
 
}

我的build.gradle文件是如下所示：

另外，我想让你k现在我的所有SDK库都是最新的，而且我的AVD上的Google Play服务也是最新的。



从我的MainActivity中，我尝试先认证用户，然后如果失败，我尝试创建一个帐户。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，但不会通知 AuthStateListener p>

因此，我的第二个活动没有启动，我的用户用户保持在同一个活动，没有应用程序崩溃。我还获得了Android监视器上的日志：

$ $ p $ W $ DynamiteModule：com.google.firebase.auth的本地模块描述符类未找到。

今天才开始。我已经在Firebase上进行了一段时间的验证，没有任何问题。我可以做什么？

解决方案

我遇到了同样的问题， b，并将其添加到项目级gradle中

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

这可以解决问题

I get the following error:

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

My code works perfectly if I decide to handle the authentication inside the onCompleteListener, but when I try to handle it from the FirebaseAuth.AuthStateListener, I get an error.

Here's my signin/signup Activity:

public class MainActivity extends AppCompatActivity implements 
AdapterView.OnItemSelectedListener {

EditText number;

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);

        proguardFiles getDefaultProguardFile('proguard-android.txt'), '

compile 'com.google.android.gms:play-services-appindexing:9.6.1'
}
apply plugin: 'com.google.gms.google-services'

Also, I would like to let you know that I have all my SDK libraries up-to-date and the Google Play Services on my AVD is also up-to-date.

From my MainActivity, I try to authenticate the user first, then if that fails, I try to create you an account. When I run this code and test the account creation process (or login process), the new account is actually created in my Firebase Console, but the AuthStateListener is not notified.

Hence my second activity is not launched and my user user remains on the same activity without the app crashing. I also get the log on the Android Monitor:

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

This started only today. I have been authenticating on Firebase for a while now with no problems. What can i do?

解决方案

I faced the same problem, googled a bit I think a maven repository on the gradle and added this to the project level gradle 

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

this would solve the problem
