Android background service get killed eventhough it has return START_STICKY in it

One of the requirements in the app that I am developing is "show something on the screen on event." Basically, I made a background service and in that, I catch the screen on intent and pass it to a BroadcastReceiver. Then, in the receiver, I open an activity and "show something". However, on Android 7-8. I think the background service get killed over a night because the next day my service is not catching anything and my receiver is not receiving. I even ask for the
<uses-permission
android:name="android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS"/>
permission, and override it, but the service still gets killed. You can find my Service class, Receiver class, and manifest below.

can't fire activity on onListItemClick in Listactivity with buttons in list?

can't fire activity on onListItemClick() in ListActivity with buttons in list?
if i touch the button, i could not get into the referred activity. it just stays there in that page even on click.

Here:
String classes[] = {"Entertainment","TextPlay","Current-Affairs"};
Current-Affairs is not a valid java identifier. see Using Java Naming Conventions for more details.
And make sure all activities Entertainment,TextPlay,... is declared in AndroidManifest.xml

i got the answer.. in java clas..
Class.forname("com.svs.blabla")
not
("com.SVS.blabla")
i.e., package name should be in lower case.

((ChuckApplication) getActivity().getApplication()).setCurrentGame(c) in Fragment

I'm currently studying a trivia style app and I'm using it in a Fragment. If I use Activities instead of Fragments, the code works:
((ChuckApplication)getApplication()).setCurrentGame(c);
But once I cast it for an activity it keeps on getting an error. The code is:
((ChuckApplication)getActivity().getApplication()).setCurrentGame(c);
The whole code is for this fragment is:
public class Activity_Home_Language extends Fragment implements OnClickListener{
Intent intent;
ImageButton btnToggle;
Button btnExam,btnReview;
TextView txtTitle;
View rootView;
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.layout_home_language, container, false);
btnToggle = (ImageButton) rootView.findViewById(R.id.btnToggle);
btnExam = (Button) rootView.findViewById(R.id.btnExam);
btnReview = (Button) rootView.findViewById(R.id.btnReview);
txtTitle = (TextView) rootView.findViewById(R.id.txtTitle);
btnToggle.setOnClickListener(this);
btnExam.setOnClickListener(this);
btnReview.setOnClickListener(this);
//FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
//transaction.add(R.id.frameContent, new Activity_Home());
//transaction.add(R.id.framePager2, new ViewPagerMunicipalities());
//transaction.add(R.id.frameDestPager, new ViewPagerDes());
//transaction.commit();
//for fading animation
return rootView;
}
#Override
public void onClick(View v) {
if(v==btnToggle){
Activity_Main.mSlideHolder.open();
}
else if(v==btnExam){
FragmentTransaction transaction = getFragmentManager().beginTransaction();
//transaction.addToBackStack(null);
transaction.replace(R.id.frameContent, new Activity_Question_Exam_Home()).commit();
}
else if(v==btnReview){
//enable this to move to move to a Activity or fragment activity
//intent = new Intent(rootView.getContext(), Activity_About.class);

The way that you're accessing the Application (or its subclass) from within your Fragment is fine and correct. Since the error you're getting is a ClassCastException, I think that your problem is that you haven't declared your custom Application subclass in the AndroidManifest.xml's application tag. For this reason, calling .getApplication() will actually return an object of type android.app.Application which cannot be typecast to your custom Application class. Perhaps you did do this in your original Activity-based project, but forgot to do so when creating the Fragments-based project?
Example of how to declare your Application subclass in the manifest file:
<application
android:name="com.example.civilserviceexamreviewer.ChuckApplication"
android:icon="..."
android:label="...">
</application>
So, the complete manifest you posted in your question should actually be:
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application
android:name="com.example.civilserviceexamreviewer.ChuckApplication"
android:allowBackup="true"

This is MyBroadcastReceiver class
package com.example.fyp_api_8_team;
import com.example.fyp_api_8_team.R;
import com.example.fyp_api_8_team_AlertMap.Show_Map;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Vibrator;
import android.util.Log;
public class MyBroadcastReceiver extends BroadcastReceiver {
private NotificationManager mNotificationManager;
public static int SIMPLE_NOTFICATION_ID;
public static String title, Message;
public static int Meetingid, pos;
#Override
public void onReceive(Context context, Intent intent) {
mNotificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notifyDetails = new Notification(
R.drawable.stat_notify_more, "You Alarm is here",
System.currentTimeMillis());
// take you to the Map class by notification click
Intent notificationIntent = new Intent(context, Show_Map.class);
PendingIntent myIntent = PendingIntent.getActivity(context, 0,
notificationIntent, 0);
// Sets the Map class for the particular notification of event
Show_Map.position = pos;
notifyDetails.setLatestEventInfo(context, title,
"Click on me to view you Meeting Location", myIntent);
notifyDetails.flags |= Notification.FLAG_AUTO_CANCEL;
notifyDetails.flags |= Notification.DEFAULT_SOUND;
mNotificationManager.notify(SIMPLE_NOTFICATION_ID, notifyDetails);
Log.i(getClass().getSimpleName(), "Sucessfully Notification Clicked");
// Vibrate the mobile phone
Vibrator vibrator = (Vibrator) context
.getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(2000);
}
}

You need to declare it like this :
<receiver android:name="com.example.fyp_api_8_team.MyBroadcastReceiver">
<intent-filter>
<action android:name="**your_action_name**" />
</intent-filter>
</receiver>
