Foreground service not running when App exits

How can I keep the foreground service running even when the user quits the app?
I've tried running the service in another process, but the service still stops after I quit the app.
My AndroidManifest.xml:
<application
android:allowBackup="true"
android:dataExtractionRules="#xml/data_extraction_rules"
android:fullBackupContent="#xml/backup_rules"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.Test"
tools:targetApi="31">
<service
android:name=".Service"
android:enabled="true"
android:process=":service"
android:exported="false" />
<activity
android:process=":activity"
android:name=".MainActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Service.java:
public class CountdownService extends Service {
NotificationManager notificationManager;
private String createNotificationChannel(String channelId, String channelName) {
NotificationChannel chan = new NotificationChannel(channelId,
channelName, NotificationManager.IMPORTANCE_NONE);
chan.setLightColor(Color.BLUE);
chan.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.createNotificationChannel(chan);
return channelId;
}
NotificationCompat.Builder builder;
#NonNull
private Notification getNotification() {
String channelId = createNotificationChannel("id", "name");
builder = new NotificationCompat.Builder(this, channelId);
return builder.setOngoing(true)
.setSmallIcon(R.mipmap.ic_launcher)
.setPriority(PRIORITY_MIN)
.setCategory(Notification.CATEGORY_SERVICE)
.setContentText("Content Text")
.setSubText("Sub Text")
.setContentTitle("Content Title")
.build();
}
#Override
public void onCreate() {
super.onCreate();
startForeground(1, getNotification());
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
return START_STICKY;
}
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
}
And in MainActivity, I start the service like this:
Intent intent = new Intent(this, Service.class);
startForegroundService(intent);
I found that this application has only one process 'service' in the phone settings, but there is no 'activity' process, what is the problem? thanks.

Define what you mean by "exit." If you mean they go into recents and swipe the app away, or go into settings and force quit, no. That's the user saying "I want this app to end". That will kill all services. Something that could run even when the user says it shouldn't is basically malware.

Notification using Firebase and Android

I am trying to make an android application where I receive notification using firebase. I followed resources available over the internet.
All I want to do is send notification from firebase, the message that I receive I want to display it in TextView in main activity.
Currently I am testing in an emulator. There are few problems that I am not able to resolve.
I am able to send notification from firebase but:
When the application is running in foreground I don't receive a notification in the android notification panel and nothing happens in the main activity too. That is the text in TextView does not change.
When the application is running in background I do receive the notification in android notification panel with message sent from firebase, clicking the notification main activity opens but the text in TextView does not change.
Firebase Messaging Service
public class VAFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "VAFirebaseMessagingS";
public VAFirebaseMessagingService() {}
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Log.d(TAG, "From: " + remoteMessage.getFrom());
if(remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
sendNotification(remoteMessage.getData().get("text"));
}
if(remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
sendNotification(remoteMessage.getNotification().getBody());
}
}
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra(Intent.EXTRA_TEXT, messageBody);
PendingIntent pendingIntent = PendingIntent
.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
notificationBuilder.setSmallIcon(R.drawable.ic_stat_name);
notificationBuilder.setContentTitle("PFIVA");
notificationBuilder.setContentText(messageBody);
notificationBuilder.setAutoCancel(true);

notificationBuilder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}

Please can someone guide what is wrong here? How can i solve the above two problems.
Thanks
After suggestions i made the below changes in Messaging Service, basically added notification channel.
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra(Intent.EXTRA_TEXT, messageBody);
PendingIntent pendingIntent = PendingIntent
.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, CHANNEL_ID);
notificationBuilder.setSmallIcon(R.drawable.ic_stat_name);
notificationBuilder.setContentTitle("PFIVA");
notificationBuilder.setContentText(messageBody);
notificationBuilder.setPriority(NotificationCompat.PRIORITY_HIGH);
notificationBuilder.setAutoCancel(true);
notificationBuilder.setSound(defaultSoundUri);
notificationBuilder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// Create the NotificationChannel, but only on API 26+ because
// the NotificationChannel class is new and not in the support library
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
int importance = NotificationManager.IMPORTANCE_DEFAULT;
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, importance);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(0, notificationBuilder.build());
}
Problem i face now is that when the app is running in background, i do receive notification in notification panel and clicking on it open main activity but the text in TextView is not updated.

Two ideas to solve your issue:
Have you register your VAFirebaseMessagingService in your AndroidManifest.xml:
Since Android 8, you must use an Notification Channel to send push notifications. Android

GCM Broadcast receiver not detcting gcm notification when the app is closed

I have a broadcast receiver which detects oncoming notifications when the app is open and in background but when the recent app is cleared the receiver is not working please suggest me ideas.
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// Explicitly specify that GcmIntentService will handle the intent.
ComponentName comp = new ComponentName(context.getPackageName(),
GcmIntentService.class.getName());
JSONObject json = new JSONObject();
try {
json.putOpt("userid", StorePreference.GetSharedPreferenceDetails(context, "memberid"));
json.putOpt("rid",StorePreference.GetSharedPreferenceDetails(context, "partnerid"));
json.putOpt("message", "Received");
BoundService.getInstance().onlinestatus(json);
} catch (Exception e) {
e.printStackTrace();
}
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
}
Manifest decleration:
<receiver
android:name="com.twogether.receivers.GcmBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name = "com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.google.android.gcm.demo.app" />
</intent-filter>
</receiver>

Try to register your receiver in manifest, use GcmListenerService to receive messages.
google example https://github.com/googlesamples/google-services has example to do this.
<!-- gcm_receiver, this is android source-->
<receiver
android:name="com.google.android.gms.gcm.GcmReceiver"
android:exported="true"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.myapp.gcm" />
</intent-filter>
</receiver>
<!-- gcm_listener service -->
<service
android:name="com.qblinks.qmote.GcmListenerService"
android:exported="false" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</service>
// Use this service to receive message
public class GcmListenerService extends com.google.android.gms.gcm.GcmListenerService {
public void onMessageReceived(String from, Bundle data) {
String message = data.getString("message");
Log.v(TAG, "From: " + from);
Log.v(TAG, "Message: " + message);
sendNotification(message);
}
private void sendNotification(String message) {
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification)
.setContentTitle("this is title")
.setStyle(new NotificationCompat.BigTextStyle().bigText(message))//multi line
.setSound(defaultSoundUri); // ring or vibrate if no ring
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(Const.NOTIFICATION_GCM /* ID of notification */, notificationBuilder.build());
}
}

When the app is close you need to wake the app up, means you need to have the permission to do that
<uses-permission android:name="android.permission.WAKE_LOCK" />
and after you can set:
AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
manager.set(AlarmManager.RTC, System.currentTimeMillis() + 5000, yourIntent);
