How to detect phone state broadcast reciever while app is closed in android "Pie"

I am trying to get phone state using TelephoneManager class and using a job scheduler i have assigned a listener for onCallStateChangeListener() ... but still android 9 "Pie" kills every background task like my listener and jobScheduler ! so how can i solve this problem and get phone state while my app is in totally closed !
Note : I tried an app like Truecaller and it works just fine after closing the app! how can i get similar behavior on my app ?

Android BroadcastReceiver onReceive() called twice on android 5.1.1 even after one register

I Could not figure out what is wrong with below code. I also checked about registering receiver twice. But that's also not the case. or may be I am missing something.

As Bharat said it's better so handle it in code. Below is a trick to do so, found here, thanks to Michael Marvick who has given detail description as well.
public class PhoneStateBroadcastReceiver extends BroadcastReceiver {
public static final String TAG = "PHONE STATE";
private static String mLastState;
#Override
public void onReceive(Context context, Intent intent) {
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if (!state.equals(mLastState)) {
mLastState = state;
Log.e(TAG, state);
}
}
}

Actually .. there is nothing wrong with the code. its System who triggers this. some time its 2 times.. other times it touches 4 times.
So the best we can do it handle it in the code itself.

I have the same behavior, and there is no issue in your code. android.intent.action.PHONE_STATE can be received few times, but Intent's bundle is always different, for example:
D/App(2001): Bundle{ state => OFFHOOK; subscription => 1; }Bundle
D/App(2001): Bundle{ incoming_number => 555555555; state => OFFHOOK; subscription => 9223372036854775807; }Bundle

Always running Service with BroadcastReceiver for Call Tapping

My Requirment
I am trying to build an application which shows a Toast whenever user makes a outgoing call from the phone. For this I am using a BroadcastReceiver to tap the call action and a service (to run Receiver always). once I start this activity, it starts showing toast when a outgoing call get initiated ...everything works well.
Issues
Sometimes I dont get any Toast Action EVEN for Outgoing call as well, is that mean service stops after some time ?
After phone reboot Toast Action for Outgoing call stops. Untill you start the servce again manually.
The code I have written is ok ? OR can it be improved ?
Below is the complete code -
MainActivity.class
public class MainActivity extends Activity

startService(intent);
}

#Bharat Once device switch off automatically service will stop, So when ever your device reboot that time you need to start service again then only you will get Toast Action, refer this example code :

Handle event Power button press if activity is Closed

How can I know if the Power button is Pressed while Activity is Closed, not screen on/off because I want to know exactly how many times Power button is Pressed.
I think I have use Broadcast or Service, but I can't find any solutions that work for me, I don't know what should I do. Here are some solutions I found but not work.
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_POWER) {
// Do something here...
Log.d("#tag", "ACTION_Down ");
}
return super.onKeyDown(keyCode, event);
}
Manifest
<uses-permission android:name="android.permission.PREVENT_POWER_KEY" />
or this, but I don't need it because It work only screen on/off, if I fast double click Power button when screen Off then It not work.
public class PowerBroadcast extends BroadcastReceiver {
private boolean screenOff;
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF))
{
screenOff = true;
Toast.makeText(context, "ACTION_SCREEN_OFF ", Toast.LENGTH_SHORT).show();
Log.d("#tag", "ACTION_SCREEN_OFF ");
}
else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON))
{
screenOff = false;
Toast.makeText(context, "ACTION_SCREEN_ON", Toast.LENGTH_LONG).show();
Log.d("#tag", "ACTION_SCREEN_On ");
}
}
}

check this out :
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
if (event.getKeyCode() == KeyEvent.KEYCODE_POWER) {
Log.i("", "Dispath event power");
//do watever u want.
return true;
}
return super.dispatchKeyEvent(event);
}

Android volatile not working?

I have an Activity class, in which I have a static flag, let's say
public static volatile flag = false;
Then in the class, I start a thread, which checks the flag and do different things.
I also have a broadcastreceiver, which sets the flag to true or false.
I though volatile will force the flag to the most recent value. But I can see my broadcastreceiver sets the static flag to true, but my thread is still getting it as false.
Am I missing something basic here? Any help would be appreciated!
Simplified Code (Updated) - So the flag is supposed to change to true after one minute. But it never did. But message from broadcast receiver shows it has been change to true

I think the problem is that you are running the receiver in its own process. From the docs for the android:process attribute of <receiver>:
If the name assigned to this attribute begins with a colon (':'), a new process, private to the application, is created when it's needed and the broadcast receiver runs in that process.
I think the receiver is modifying a process-local version of TestService.flag, not the one being used by TestService. Try removing the android:process attribute from the <receiver> tag in your manifest.

From this link
http://www.javamex.com/tutorials/synchronization_volatile.shtml
Essentially, volatile is used to indicate that a variable's value will
be modified by different threads.

I really hope your service thread is not this one (I don't see any other one):
private class MyTopThread extends Thread {
#Override
public void run() {
while (true) {
try {
Thread.sleep(150);
Log.d(TAG, "Flag is " + TestService.flag);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
Because you have while(true) here, not while(!flag) as it should be.
