Android中的Firebase推送通知不起作用

我試圖將Firebase推送通知服務添加到我的應用程序中我遵循了Firebase文檔中的所有步驟，但是當我嘗試發送通知失敗時，我的手機未收到任何通知，請有人幫我解決這個問題。 的build.gradle（APP）Android中的Firebase推送通知不起作用

android { 
    //... 
    } 
    buildTypes { 
     release { 
      //.. 
     } 
    } 
} 
dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 
     exclude group: 'com.android.support', module: 'support-annotations' 
    }) 
    ..... 
    //notifications 
    compile 'com.google.firebase:firebase-core:10.2.1' 
    compile 'com.google.firebase:firebase-messaging:10.2.1' 
    compile 'com.firebase:firebase-jobdispatcher:0.5.2' 
    testCompile 'junit:junit:4.12' 
} 
apply plugin: 'com.google.gms.google-services'

的build.gradle

dependencies { 
     classpath 'com.android.tools.build:gradle:2.2.3' 
     classpath 'com.google.gms:google-services:3.0.0' 
    }

你仔細檢查你的火力地堡的憑據，如果他們正確和準確的？您是否從Firebase項目下載並複製到Android應用目錄中的google-services.json文件？ – ADimaano

@ADimaano是的，我確定 – MrMR

我認爲你缺少你的清單文件的服務部分這一部分：

<service 
    android:name=".ProjectFirebaseInstanceIDService"> 
    <intent-filter> 
     <action android:name="com.google.firebase.INSTANCE_ID_EVENT" /> 
    </intent-filter> 
</service>

和類應該是這個樣子：

package <your project package signature>; 

import com.google.firebase.iid.FirebaseInstanceId; 
import com.google.firebase.iid.FirebaseInstanceIdService; 

public class ProjectFirebaseInstanceIDService extends FirebaseInstanceIdService 
{ 
    @Override 
    public void onTokenRefresh() { 
      super.onTokenRefresh(); 

      String refreshedToken = FirebaseInstanceId.getInstance().getToken(); 

     sendRegistrationToServer(refreshedToken); 
    } 

    private void sendRegistrationToServer(String token) { 
     // Add your implementation for notification purposes 
    } 
}

你需要，要將消息發送到訂閱主題的設備或設備組或設備。

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService { 
private static final String TAG = MyFirebaseInstanceIDService.class.getSimpleName(); 

@Override 
public void onTokenRefresh() { 
    super.onTokenRefresh(); 
    String refreshedToken = FirebaseInstanceId.getInstance().getToken(); 

    Log.d(TAG,"New Token"+ refreshedToken); 
}

}

使用這項服務，並添加此服務體現

<service android:name=".services.MyFirebaseInstanceIDService"> 
      <intent-filter> 
       <action android:name="com.google.firebase.INSTANCE_ID_EVENT" /> 
      </intent-filter> 
     </service>
