UsageStats always the same when i start the method every x seconds

Im trying to make a service that would provide data of usagestat every x second. However i always getting the same value after x second. I already clear the map to include new data set from usagemanager. below is my service class thank you in advance.
I do know that in order to retrieve queries every x time, we may use queryevent. However, the total time in foreground for this fit my project, and i already tested using the code for adapter. In the adapter, it do retrieve usage time, however it only provide new value on restarting the activity where the adapter used.

I want to make Background Service to add item to RecyclerView every 24 hours

I'm trying to start a service that adds an item to RecyclerView every 24 hours (every day). I used this code but it doesn't work:

public class BackgroundService extends Service {

public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
this.context = this;
this.isRunning = false;
this.backgroundThread = new Thread(addNewNote);
}
private Runnable addNewNote = new Runnable() {
#Override
public void run() {
Log.e("isRunning", "Yeeeeeeeeeees!");
pref = getApplicationContext().getSharedPreferences("checkStates", 0);
String checkMorningState = pref.getString("morning", "False");
String checkEveningState = pref.getString("evening", "False");
String checkNightState = pref.getString("night", "False");
String checkEchuraistState = pref.getString("echuraist", "False");
String checkConfessState = pref.getString("confess", "False");
String checkBibleState = pref.getString("bible", "False");
String writeYourNotes = pref.getString("writeNotes", "");
SimpleDateFormat sdf = new SimpleDateFormat("E", new Locale("ar"));
final SimpleDateFormat sdf2 = new SimpleDateFormat("yyyy.MM.dd");
final Timestamp timestamp = new Timestamp(System.currentTimeMillis());
Date = sdf2.format(timestamp).toString();
if(checkMorningState.equals("True")){
isMorningChecked = "+";
}else{
isMorningChecked = "-";
}
if(checkEveningState.equals("True")){
isEveningChecked = "+";
}else{
isEveningChecked = "-";
}
if(checkNightState.equals("True")){

}else{

}

}else{

}

}else{
isConfessChecked = "-";
}
if(checkBibleState.equals("True")){

}else{

}
AppDatabase db = Room.databaseBuilder(getApplicationContext(), AppDatabase.class, "Note").allowMainThreadQueries().build();
db.userDao().insertAll(new Note(sdf.format(timestamp), sdf2.format(timestamp).toString(), isMorningChecked, isEveningChecked, isNightChecked, isEchuraistChecked, isConfessChecked, isBibleChecked, writeYourNotes));
stopSelf();
}
};
#Override
public void onDestroy() {
super.onDestroy();
this.isRunning = false;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if(!this.isRunning){
this.isRunning = true;
this.backgroundThread.start();
}
return START_STICKY;
}
}
BoardCastReceiver.java
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
context.startService(new Intent(context, BackgroundService.class));
}
}
Home.java
Intent alarm = new Intent(this, AlarmReceiver.class);
boolean alarmRunning = ((PendingIntent.getBroadcast(this,0,alarm,PendingIntent.FLAG_NO_CREATE)) != null);
if(alarmRunning == false){
PendingIntent pendingIntent = PendingIntent.getBroadcast(this,0,alarm,0);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime(), 1000, pendingIntent);
I have tried this but the Service works once or twice and then it stops and sometimes it gives me the following error:
java.lang.IllegalStateException: Not allowed to start service Intent

Background service can not be used for long running tasks on Android 8.0 onwards. Please use JobScheduler API or Workmanager to achieve the desired results. Consult the following link for details.

The app can't manage more than a push notification

I'm tried to manage a set of push notifications.
1. My first problem is that only last notification set up receive my smartphone. I believe that it hasn't create new instance but it overwrite the unique istance. How can I solve it?
2. My second problem is that i want that from app, the user can delete a schedule of a determinate notification.

Change this line
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
To
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, notificationIntent, PendingIntent.FLAG_ONE_SHOT); //Here 0 is the intent requestcode.
Make sure intent request code is unique in order to differentiate intents.

java.lang.ArrayIndexOutOfBoundsException: length=2; index=2

Hi in the below code I am getting array index out of bounds exception.Here friend array it's giving two values.
For ex:
friendinfo[0]=user1,friendinfo1=user2 and with checkbox when i am selecting user1 I want to show friend.length to 2 and checked value should be 1.
this is sample screen how to add the use3 and user1 when i am clicking the create button.

You probably wanted to write :
if(checkBoxState[i]==isChecked)
if checkBoxState and friend arrays have the same length, checkBoxState[friend.length] is out of bounds, since the indices of an array are from 0 to length - 1.
Also note that your if condition contained an assignment operator = instead of a comparison operator ==.

Just use the index inside the for loop. Also since isChecked is already a boolean you can just assign it directly to checkBoxState
for (int i = 0; i < friend.length; i++) {
checkBoxState[i] = isChecked;
}

You are trying to access the index 2nd position in an array that has only a length of 2 (positions 0 and 1).
So please change the code as below,
if(checkBoxState[i]==isChecked)

how to get current position in FragmentPagerAdapter?

I have an adapter that extends FragmentPagerAdapter and takes advantage of the ICS style actionBar. This actionbar has actions that take input from the currently selected page.
Specifically, I have a screenshot icon in the actionbar that takes the url of the current page and displays any screenshots from that url. However, I dont know how to retrieve the currently selected page.
How can I implement something like a
public int getActivePage() {
return position;
Im still working on the viewpager implementation, so my code is still heavily reliant on examples, so disregard the mess :P
The problem areas are marked below.

Heres what I mean by the currently selected page.

I believe what you are looking for is onPageChangedListener(). This method belongs to the TitlePageIndicator. Something like...
indicator.setOnPageChangedListener(new OnPageChangedListener() {
// Implement unimplemented methods...
});

you can also ask to viewpager
in java
ViewPager pager = (ViewPager) findViewById(android.R.id.list);
pager.getCurrentItem()
in kotlin
pager.currentItem
