当我的应用被终止时,我无法从我的应用服务器接收到我设置的通知。我之前的gradle是这样的:
implementation "com.google.firebase:firebase-messaging:17.0.0"
implementation "com.google.firebase:firebase-invites:16.0.0"有了这个gradle配置,我可以在前台和后台收到通知,甚至在应用程序被滑动时也能收到通知
我更新了我的forebase-messanging,所以这是我的新gradle的firebase-messanging:
implementation "com.google.firebase:firebase-messaging:18.0.0"下面是我更新后的当前Service类
public class MyService extends FirebaseMessagingService
{
public static final String ACTION = "action";
public static final String EXTRA_DATA = "extra_data";
public static final String MESSAGE = "message";
private RemoteMessage.Notification mNotification;
@Override
public void onNewToken(String refreshedToken) {
super.onNewToken(refreshedToken);
LOGE(TAG, "Refreshed token: " + refreshedToken);
}
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
String from = message.getFrom();
mNotification = message.getNotification();
Map<String, String> data = message.getData();
LOGE(TAG, "Received FCM message from : " + from + " data : " + data);
}
}在这个新版本中,当应用程序被滑动时,仍然可以在系统托盘中接收通知吗?如果是这样,有什么想法吗?

您是否在清单中定义了如下服务类?:
<service
android:name=".MyService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>如果问题仍然存在,即使在那之后。添加下面的方法并从您的onMessageReceived THis调用它可以解决任何类型的问题。
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, MainActivity.class); // Put your own launcher Activity
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());
}上面的方法取自Firebase repository。

我在某些手机上也遇到过同样的情况,比如华硕Zenfone。当我从当前任务/应用程序列表中滑动应用程序时,firebase消息不会发送,所有后台服务/作业都会停止/从不触发。但在三星等其他制造商,滑动应用程序仍然可以收到这些信息。
我认为除了“白名单”之外别无他法--用户必须手动去做,忘记它在Zenfone里叫什么。
