Question

我正在使用带有数据消息传递功能的FCM，并且可以处理前台和后台通知，但是当重新启动手机或应用程序被终止时无法接收它们（通过在任务管理器中滑动来终止任务）。

            android:allowBackup="true"

                    <action android:name="android.intent.action.MAIN" />

                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
            <!-- Notification -->
            <service
                android:name="com.example.tadad.firebasetestDOUBLE.notification.SomeInstanceIDListenerService">
                <intent-filter>
                    <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
                </intent-filter>
            </service>
            <service
                android:name="com.example.tadad.firebasetestDOUBLE.notification.SomeFirebaseMessagingService">
                <intent-filter>
                    <action android:name="com.google.firebase.MESSAGING_EVENT" />
                </intent-filter>
            </service>
        </application>

    </manifest>

代码：

public class SomeFirebaseMessagingService extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        int a = 4;

        sendNotification("Smth", "Receive please!");

    }
}
public class SomeInstanceIDListenerService extends FirebaseInstanceIdService {

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

    private void sendRegistrationToServer(String token) {
        // TODO: Implement this method to send token to your app server.
    }
}

Android，FireBase云消息传递，（FCM）
