我有一个android应用程序,必须使用android o及以上版本的服务在后台运行,我知道后台服务已被系统杀死,因此我将 startForground
与正确的通知,但有时这些通知没有出现,可能是由于移动设置
所以,如果我们来自
设置->应用程序->我的应用程序名称->通知->我的后台服务和 服务
因此,我的问题是我该如何实用地启动或检查这些“我的后台服务和服务”。
答案 0 :(得分:0)
从Android O,
我们需要为每个在后台到达的通知设置频道ID。
清单中需要添加
<meta-data
android:name="com.google.firebase.messaging.default_notification_channel_id"
android:value="default_channel_id"/>
在您的消息服务类中,
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
sendNotification(remoteMessage.getNotification().getBody());//Considering you have message in your body.
}
和
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
String channelId = getString(R.string.default_notification_channel_id);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.ic_stat_ic_notification)
.setContentTitle(getString(R.string.fcm_message))
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// Since android Oreo notification channel is needed.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId,
"Channel human readable title",
NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
