Question

我尝试使用Google云消息从我的应用服务器向我的应用发送推送通知消息该应用在Android模拟器上运行良好，但有些设备没有收到通知

这里是FCMMessagingService.java

public class FCMMessagingService extends FirebaseMessagingService {

String title;String message;

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

    if(remoteMessage.getNotification() != null){
         title = remoteMessage.getNotification().getTitle();
         message = remoteMessage.getNotification().getBody();
        Log.d("Message body", remoteMessage.getNotification().getBody().toString());
    }


    Map<String, String> data = remoteMessage.getData();
    title = data.get("company");
    message = data.get("message");
    Log.d("Message body", remoteMessage.getData().toString());

    Intent intent = new Intent(this,MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_ONE_SHOT);
    NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
    builder.setContentTitle(title);
    builder.setContentText(message);
    builder.setSmallIcon(R.mipmap.ic_launcher);
    builder.setAutoCancel(true);
    builder.setContentIntent(pendingIntent);
    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(0, builder.build());

    super.onMessageReceived(remoteMessage);
}
}

这里是Manifest.xml

 <uses-permission android:name="android.permission.INTERNET"></uses-permission>
<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <service android:name=".FcmInstanceIdService">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT"></action>
        </intent-filter>
    </service>
    <service
        android:name=".FCMMessagingService"
        android:stopWithTask="false">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT"/>
        </intent-filter>
    </service>

</application>

如果您在应用程序位于前台时收到通知，那么您只需使用data payload代替notification payload即可同时使用data payload但data payload可以使用应用程序在后台甚至关闭。我建议您仅使用payload，因为它的工作时间是100％。我的应用程序之一在应用程序关闭时没有收到通知但我同时使用了data payload然后我只将其更改为{{1}}并且工作正常。

在某些设备上关闭应用时，Firebase推送通知无法正常工作
