我正在使用Firebase并测试在应用程序处于后台时从服务器发送通知到我的应用程序。通知发送成功,它甚至出现在设备的通知中心,但当通知出现或即使我点击它,我的FCMessagingService中的onmessagerreceived方法永远不会被调用。
当我测试这个,而我的应用程序是在前台,onmessagerreceived方法被调用,一切工作正常。问题发生在应用程序在后台运行时。
这是我有意为之的行为吗,或者我有办法解决这个问题吗?
这是我的FBMessagingService:
import android.util.Log;
import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;
public class FBMessagingService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.i("PVL", "MESSAGE RECEIVED!!");
if (remoteMessage.getNotification().getBody() != null) {
Log.i("PVL", "RECEIVED MESSAGE: " + remoteMessage.getNotification().getBody());
} else {
Log.i("PVL", "RECEIVED MESSAGE: " + remoteMessage.getData().get("message"));
}
}
}
我认为告诉您将消息类型更改为数据的答案对您来说很清楚。
但有时,如果你不能决定你收到的消息类型,你必须处理它。我把我的方法贴在这里。您刚刚实现了FirebaseMessagingService并在handlIntent()方法中处理您的消息。从那里你可以自定义你自己的通知。你可以实现你自己的方法sendYourNotificatoin()
class FCMPushService : FirebaseMessagingService() {
companion object {
private val TAG = "FCMPush"
}
override fun handleIntent(intent: Intent?) {
Logger.t(TAG).i("handleIntent:${intent.toString()}")
val data = intent?.extras as Bundle
val remoteMessage = RemoteMessage(data)
if (remoteMessage.data.isNotEmpty()) {
val groupId: String = remoteMessage.data[MESSAGE_KEY_GROUP_ID] ?: ""
val title = remoteMessage.notification?.title ?: ""
val body = remoteMessage.notification?.body ?: ""
if (title.isNotEmpty() && body.isNotEmpty())
sendYourNotificatoin(this, title, body, groupId)
}
}
}
看看@Mahesh Kavathiya的答案。对于我的情况,在服务器代码中只有这样:
{
"notification": {
"body": "here is body",
"title": "Title",
},
"to": "sdfjsdfonsdofoiewj9230idsjkfmnkdsfm"
}
您需要更改为:
{
"data": {
"body": "here is body",
"title": "Title",
"click_action": "YOUR_ACTION"
},
"notification": {
"body": "here is body",
"title": "Title"
},
"to": "sdfjsdfonsdofoiewj9230idsjkfmnkdsfm"
}
然后,如果app在后台,默认的活动意图extra会得到"data"
好运!
