无法创建具有最新Firebase版本的用户。我得到一个W / DynamiteModule和W / GooglePlayServicesUtil

Question

我想将Firebase身份验证和Firebase云消息传递添加到我的应用程序。遵循最新的入门指南后，我无法创建新用户。我还考虑了此代码示例。我在Firebase控制台中启用了：

• 使用 电子邮件/密码登录
• 并出于测试目的 匿名登录

OTUPUT：

D/EmailPassword: onAuthStateChanged:signed_out
D/EmailPassword: createAccount:mail
W/DynamiteModule: Local module descriptor class for com.google.firebase.auth not found.
W/GooglePlayServicesUtil: Google Play services out of date.  Requires 10084000 but found 9877470

我发现了类似的问题，但是所有答案并没有帮助我解决问题……我认为这只是一个小傻瓜错误，但我无法解决问题。

我在应用程序级别上的gradle文件如下所示：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.3"
    defaultConfig {
        applicationId "app.radiant.c.lly"

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    compile 'com.google.firebase:firebase-messaging:10.0.0'
}

// Firebase Plugin
apply plugin: 'com.google.gms.google-services'

我在项目级别上的gradle文件如下所示：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files

        // Added this line for Firebase
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我有一个外部数据库，用于存储登录的用户。在Firebase中，我只想使用默认密码存储数据库中的电子邮件地址。为此，我只创建了一个按钮，该按钮应在按下时将用户存储在Firebase上。

public class InboxFragment extends Fragment {

    View view;
    Activity callingActivity;
    Account account;
    ListView chats;
    Button btn;

    ArrayList<String> exampleContent = new ArrayList<>();
    ArrayAdapter<String> adapter;

    // Firebase instance variables
    private static final String TAG = "EmailPassword";
    private FirebaseAuth mAuth;
    private FirebaseAuth.AuthStateListener mAuthListener;
    String username;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.fragment_inbox, container, false);
        callingActivity = getActivity();
        account = (Account) callingActivity.getApplication();

        // Firebase
        // [START initialize_auth]
        mAuth = FirebaseAuth.getInstance();
        // [END initialize_auth]

        // [START auth_state_listener]
        mAuthListener = new FirebaseAuth.AuthStateListener() {
            @Override
            public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
                FirebaseUser user = firebaseAuth.getCurrentUser();
                if (user != null) {
                    // User is signed in
                    Log.d(TAG, "onAuthStateChanged:signed_in:" + user.getUid());
                } else {
                    // User is signed out
                    Log.d(TAG, "onAuthStateChanged:signed_out");
                }
                // [START_EXCLUDE]
                //updateUI(user);
                // [END_EXCLUDE]
            }
        };
        // [END auth_state_listener]

        btn = (Button) view.findViewById(R.id.addUsernameBtn);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                createAccount(account.getEmail(), "empty");
            }
        });

        // Code
        chats = (ListView) view.findViewById(R.id.userChatList);

        // Add example content to array
        exampleContent.add("Chat 1");
        exampleContent.add("Chat 2");
        //exampleContent.add(username);

        adapter = new ArrayAdapter<String>(callingActivity, android.R.layout.simple_list_item_1, exampleContent);
        chats.setAdapter(adapter);

        chats.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Intent i = new Intent(getActivity(), ChatActivity.class);
                startActivity(i);
            }
        });

        return view;
    }

    // [START on_start_add_listener]
    @Override
    public void onStart() {
        super.onStart();
        mAuth.addAuthStateListener(mAuthListener);
    }
    // [END on_start_add_listener]

    // [START on_stop_remove_listener]
    @Override
    public void onStop() {
        super.onStop();
        if (mAuthListener != null) {
            mAuth.removeAuthStateListener(mAuthListener);
        }
    }
    // [END on_stop_remove_listener]

    private void createAccount(String email, String password) {
        Log.d(TAG, "createAccount:" + email);
        /*if (!validateForm()) {
            return;
        }*/

        //showProgressDialog();

        // [START create_user_with_email]
        mAuth.createUserWithEmailAndPassword(email, password)
                .addOnCompleteListener(getActivity(), new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        Log.d(TAG, "createUserWithEmail:onComplete:" + task.isSuccessful());

                        // If sign in fails, display a message to the user. If sign in succeeds
                        // the auth state listener will be notified and logic to handle the
                        // signed in user can be handled in the listener.
                        if (!task.isSuccessful()) {
                            Log.e(TAG, "ERROR");
                            /*Toast.makeText(EmailPasswordActivity.this, R.string.auth_failed,
                                    Toast.LENGTH_SHORT).show();*/
                        }

                        // [START_EXCLUDE]
                        //hideProgressDialog();
                        // [END_EXCLUDE]
                    }
                });
        // [END create_user_with_email]
    }

}

但这是行不通的。我得到了输出（请参阅问题的顶部）。

Answer 1

这就是问题：

W/GooglePlayServicesUtil: Google Play services out of date.  Requires 10084000 but found 9877470

如果您在模拟器上运行，则需要根据所模拟的API级别降级到Play
Services和Firebase库的9.8.0或9.6.1版本。没有发布的仿真器映像支持版本10.0.0。

如果您在真实设备上运行，则需要更新Google Play服务的版本。当前版本是10.0.84。您可以转到设置>应用程序管理器> Google
Play服务，查看手机上安装的版本。

此日志消息不表示问题。它似乎在正常操作期间输出：

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