Phone manager/Battery optimizer app kills foreground service

-I am developing an application that records user location in a .csv file and uploads them to firebase storage and I've written a service to accomplish this. The service needs to run indefinitely until the user stops it (by unchecking a switch from the activity that launched the service). The service runs in foreground and after running for 15-20 minutes, the phone manager app gives "resource intensive app found" notification and kills the service. onDestroy() never gets called!. I return START_STICKY which is supposed to recreate the service and call onStartCommand() again but the service never gets created again!
I've seen some people write workarounds for this problem but they target specific android versions. My app targets android Pie and I haven't seen any "generic" solution to this problem yet. All solutions are either device/brand specific or API level specific. For now I'm testing the app on Huawei Y7 prime 2018 (Android O) and on my device, i got around this by manually disallowing the phone manager app to manage my application, this way the service does run indefinitely until the user kills it from the app. The nature of the application is such that i need minimum user engagement and i don't expect the users to go through the hassle of manually disabling my app from battery optimizer/phone manager app. My LocationService.java class is attached, if somebody could please provide either a better implementation of this service or some generic method to keep it alive, that'd be great. Even some hack to make sure that onDestroy() gets called before the system kills the application would work!

Running a background service which never stops (or always restarts)

I'm building an Android Wear service which runs in the background and logs device data every three minutes. For this logging, I am using a Handler, which records the values and then has an interval of three minutes. This will be used to monitor user behaviour for one month, and as such it should not randomly stop.
I have also used android.intent.action.BOOT_COMPLETED in my manifest and this successfully runs the application whenever the watch is booted.
My issue is that the service can run correctly for 12 hours...and then just suddenly stop. The amount of time appears to be non-deterministic, as sometimes it will stop after 40 minutes. I suspect it's being killed by Android, but in this case I would like it to restart. I have included return START_STICKY in my service and this should minimise the chance of it being killed.
In some solutions, I have seen onDestroy() overridden and a refresh broadcast being sent to the service. While this appears to work, the onDestroy() function is being called every time the Handler completes one piece of work. This leads to the service restarting every three minutes, rather than when the application is actually killed by Android.
I have also looked at the intent actions to see whether my service could be called at regular intervals. However, aside from android.intent.action.BOOT_COMPLETED, all the useful ones cannot be registered in the Manifest file. Since the service will not be running, registerReceiver() would serve little purpose.
Does anybody know of a technique to either a) guarantee a service will not be killed by Android; or b) guarantee that a service will always be restarted after it has been killed. Any help would be greatly appreciated, as I've even started considering writing a Cron job on the device and setting it to execute my app every three minutes! I've also looked at the AlarmManager class, but I fear it is as likely to be killed if running for long periods.

my service is lost every time phone restarts

i'm making a service
which works perfactly well so far,
but everytime the phone restarts, the service is lost,
how do i make the service restart every time the phone shuts off, and turns back on again , (if it was running out of battery, or if user has done a restart)
is there a simple way of making it ?
this is my service >

THANKX EVERYONE IN ADVANCe ! "_
i wouldn't know how to live without this site lol..

You need to make a receiver which will listen to intent.Boot complete.
And then in on receive(), you can start your service.

You need to add Receiver Class.
Add below permission in AndroidManifest.xml file.
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Add below statements in Application Tag in AndroidManifest.xml
<receiver android:name=".YourBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter></receiver>
YourBroadcastReceiver.java
package com.test;
public class MyBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent startServiceIntent = new Intent(context, MyService.class);
context.startService(startServiceIntent);
}
}

Show notification from background started service

So i'm using asmack library to listen for incoming xmpp packets. I've got the service implemented. It's started, bound, a method is run and then it's unbound. The service creates a PacketListener to get incoming messages, and displays a notification when a new message comes in. This all works while the app is the active activity, but doesn't work when it's fully closed (swiped away in the window list) and it's just the service running, the PacketListener doesn't fire. It fires as soon as the app is reopened though, firing off all notifications. I'm looking to get those notifications fired as they come in, instead of the service being suspended, if you will. The code for the service is here:

message.setRecipient(Preferences.Account.getUsername() + "#"

String fullSender = m.getFrom();
String address = fullSender.substring(0, fullSender.indexOf('/'));
message.setSender(address);
message.setContents(m.getBody());
Program.showMessageNotification(message, 9127);
}
}
}
}
and the code for the starting/binding the service is here:
public static void init() {
if (!initialized) {
// Call other portions of init code first
SmackAndroid.init(context);
Preferences.init();
// Set up our variables
contacts = GlazedLists.threadSafeList(new BasicEventList<Contact>());
// Start up the xmpp connection
Intent ixmpp = new Intent(context, XMPPService.class);
context.startService(ixmpp);
context.bindService(ixmpp, xmppConnection, Context.BIND_AUTO_CREATE);
initialized = true;
}
}
So as I said, i want to receive notifications from the service running in the background when the foreground activity is closed. Is there any way of doing this? Maybe have it in it's own process? Something else?
EDIT: the ongoing notification sticks around and works when clicked, in case you're wondering

use startforeground method
http://developer.android.com/reference/android/app/Service.html#startForeground%28int,%20android.app.Notification%29
in onCreate of service
public void onCreate() {
startForeground (int id, Notification notification)
}

NotificationListenerService Implementation

I am trying to implement NotificationListnerService which is added in android 4.3 but I am not able to get the notification details.
My code are as below
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
mBuilder.setSmallIcon(R.drawable.ic_launcher);
mBuilder.setContentTitle("notification test");
mBuilder.setContentText("Notification text");
mBuilder.setAutoCancel(true);
Intent resultIntent = new Intent(this, ResultActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(ResultActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager manager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(1, mBuilder.build());
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
public class NotificationListenerTesting extends NotificationListenerService{
public static String TAG = "NotificationListenerTesting";
//private StatusBarNotification[] mStatusBarNotification;
#Override
public void onCreate(){
super.onCreate();
Log.d(TAG, "Inside on create");
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onNotificationPosted(StatusBarNotification sbn) {
TAG = "onNotificationPosted";
Log.d(TAG, "id = " + sbn.getId() + "Package Name" + sbn.getPackageName() +
"Post time = " + sbn.getPostTime() + "Tag = " + sbn.getTag());
}
#Override
public void onNotificationRemoved(StatusBarNotification sbn) {
TAG = "onNotificationRemoved";
Log.d(TAG, "id = " + sbn.getId() + "Package Name" + sbn.getPackageName() +
"Post time = " + sbn.getPostTime() + "Tag = " + sbn.getTag());
}
}
Android manifest file is
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.notificationtest"
android:versionCode="1"
android:versionName="1.0" >

<intent-filter>
<action android:name="android.service.notification.NotificationListenerService"/>
</intent-filter>
</service>
</application>
</manifest>
but after notification click or on notification post NotificationListenerService is not getting called , Whats wrong in this or did I miss somthing ? How to implement it ?

You need to grant access to your app to read notifications:
"Settings > Security > Notification access" and check your app.

Inside the NotificationListenerService you need a looper to communicate with GUI thread so you can create a broadcast to handle the GUI interaction.
Hope this example will help you.

At least one problem with your code is that your implementation of onBind()
There is no necessity to override this method. But if you must, then at least return the IBinder returned by the superclass.
#Override
public IBinder onBind(Intent intent) {
return super.onBind(intent);
}

It might be a bit late. But a few months ago I also struggled with making NotificationListenerService work.
Since then I`ve learned how to implement it and felt like building a implementation tutorial to help others who went through the same as me
If anyone is interested, check the project here:
https://github.com/Chagall/notification-listener-service-example
Hope it helps someone who is struggling with it.

I know its too late to answer the question , but as I was not able to find Settings > Sound and notifications -> Notification access, so I directly allow access of notifications to my app by firing this intent:
startActivity(new Intent(Settings.ACTION_NOTIFICATION_LISTENER_SETTINGS));

I ran into the same problem and have found some clues for that.
NotificationListenerService may not be running unless you call bindService() to start it.
Sometimes it started automatically when you enabled "Notification access" and sometimes it's not.

I am doing the same thing as in GitHub, but still I am not going into the notification class.

The notification that you build does not have "tickerText." I have found that if the notification does not have tickerText, onNotificationPosted does not get called.
In your code add mBuilder.setTicker( "your text here" ).
onNotificationPosted should now be called assuming that the rest of the NotificationListenerService set up is copacetic.
