[英]On Android setting badge number on app icon when app is in background or killed when receiving notification like facebook app
[英]Not receiving notification when the app is killed
我創建了一個程序,它將在 android 應用程序中添加通知。 但不知何故,當應用程序被殺死時我無法收到通知
這是我的 FirebaseMessagingService
public class FirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
if (remoteMessage.getData() != null)
sendNotification(remoteMessage);
}
private void sendNotification(RemoteMessage remoteMessage){
Map<String, String> map = remoteMessage.getData();
String title = map.get("title");
String content = map.get("content");
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
String NOTIFICATION_CHANNEL_ID = "MyAndroidChannel";
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
@SuppressLint("WrongConstant") NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID,
"My Notification", NotificationManager.IMPORTANCE_MAX);
notificationChannel.setDescription("This is a sample notification");
notificationChannel.enableLights(true);
notificationChannel.setLightColor(Color.RED);
notificationChannel.setVibrationPattern(new long[]{0,1000,500,1000});
notificationChannel.enableVibration(true);
}
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);
builder.setAutoCancel(true)
.setDefaults(Notification.DEFAULT_ALL)
.setWhen(System.currentTimeMillis())
.setSmallIcon(R.drawable.ic_launcher_foreground)
.setTicker("Hearty365")
.setContentTitle(title)
.setContentText(content)
.setContentInfo("info");
notificationManager.notify(1,builder.build());
}
}
我添加了一個小圖標、標題和內容。 此外,我還定義了一個頻道 ID。
但我不知道發生了什么......當應用程序運行並處於后台模式時,可以接收通知。 但是當應用程序終止時它沒有收到。
這是我的 FirebaseMessagingIdService class
public class FirebaseMessagingIdService extends FirebaseInstanceIdService {
@Override
public void onTokenRefresh() {
super.onTokenRefresh();
sendNewTokenServer(FirebaseInstanceId.getInstance().getToken());
}
private void sendNewTokenServer(String token){
Log.d("TOKEN",String.valueOf(token));
}
}
我不認為我做錯了什么,但請幫助我。
提前致謝。
您嘗試從哪里發送消息? 如果您從服務器發送,請嘗試在通知 object 中包含數據有效負載。 然后即使應用程序關閉,也只有應用程序會收到消息。
