FCM：没有调用onMessageReceived，即使将msg发送到fcm后也没有通知？
我正在开发一个应用程序，我想通过PHP实现FCM推送通知。
所以我制作了两个java文件：1.FirebaseInstanceID（工作正常并在数据库中正确获取令牌）2.FirebaseMessagingSerivice（未调用）
我的FirebaseMessagingService.java
package com.example.xyz; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Intent; import android.support.v4.app.NotificationCompat; import com.google.firebase.messaging.RemoteMessage; public class FirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService{ @Override public void onMessageReceived(RemoteMessage remoteMessage) { showNotification(remoteMessage.getData().get("message")); } private void showNotification(String message) { Intent i = new Intent(this,Dashboard.class); i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); PendingIntent pendingIntent = PendingIntent.getActivity(this,0,i,PendingIntent.FLAG_UPDATE_CURRENT); NotificationCompat.Builder builder = new NotificationCompat.Builder(this) .setAutoCancel(true) .setContentTitle("FCM Test") .setContentText(message) .setSmallIcon(R.drawable.common_google_signin_btn_icon_dark) .setContentIntent(pendingIntent); NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); manager.notify(0,builder.build()); } } 当我运行我的php脚本向FCM发送消息时的结果：
{\"multicast_id\":7077449602201888040,\"success\":1,\"failure\":0,\"canonical_ids\":0,\"results\":[{\"message_id\":\"0:1465110073498648%d215149df9fd7ecd\"}]}
但我仍然没有得到任何通知，所有的配置，如api密钥，包名称（在fcm控制台，我的项目）都被检查，他们没事。
当我通过在FirebaseMessagingService.java中的onMessageReceived（）创建断点来调试应用程序时，它没有通过它，并且当消息通过php脚本推送到fcm服务器时，应用程序正常运行。
我的Dashboard.java
public class Dashboard extends AppCompatActivity { private Toolbar toolbar; private DrawerLayout drawer_layout; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_dashboard); toolbar=(Toolbar) findViewById(R.id.app_bar); setSupportActionBar(toolbar); getSupportActionBar().setDisplayShowHomeEnabled(true); drawer_layout=(DrawerLayout) findViewById(R.id.drawer_layout); NavigationDrawerFragment drawerfragment= (NavigationDrawerFragment) getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer); drawerfragment.setUp(R.id.fragment_navigation_drawer,drawer_layout,toolbar); FirebaseMessaging.getInstance().subscribeToTopic("test"); FirebaseInstanceId.getInstance().getToken(); }
但我的仪表板活动包含一个片段。我不知道它是否有问题。
AndroidManifest.xml中
logcat的

不幸的是， Usman Iqbal的回答并不完全正确。 官方Android文档使用MESSAGING_EVENT：
资料来源： https ： //firebase.google.com/docs/cloud-messaging/android/receive#edit-the-app-manifest
常见的错误
android:name="YourApplicationPackageName.YourFirebaseMessagingServiceName"
您需要更改AndroidManifest.xml某些部分。
