How to save state of a progressbar when app is killed?

I am building a simple downloader app, with a pause/resume button. When I click on pause button and kill the app the download progress isn't shown anymore, after I open the app again. I want to save the download progress state even if the app is killed. Can anyone help me with this? I'm building the app using download manager pro library from github.
here's the code:

I don't know how you want to save the state but I do know that an activity has a onStop() method that you can override.
The onStop() method runs when the app is killed so I would imagine you would want to do your "saving" in this method.
As for saving something I believe you would want to use the SharedPreferences class. You can find more information about that here.
You can find the lifecycle of an activity here
hope this helps

Save the progress on SharedPreferences onDestroy() and retrieve it from there when activity is created.
Cache:
#Override
protected void onDestroy() {
super.onDestroy();
SharedPreferences sharedPreferences = getSharedPreferences("space_name", MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putInt("progress", progress).apply();
}
And retrieve:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SharedPreferences sharedPreferences = getSharedPreferences("space_name", MODE_PRIVATE);
progress = sharedPreferences.getInt("progress", 0); // 0 default value in case is empty
}

Not able to connect to REST API inside a service in some devices

I am using retrofit 1.9 in order to create and use connections with server , its working perfectly in app , but when i am trying to hit api in a service , it is returning me this error

Try to use execute instead enqueue call.Services is already on different thread. So if you are making a network call on different thread you should run api on same thread.

Location update from a repetitive task not working when mobile screen goes off

I have made a location update foreground service which gets locations directly(requestLocationUpdates) when interval is less than 30 secs and if its more than 30 sec, I use ScheduledExecutorService to get the location result and pool location results to get the best location. Only issue I am facing is I am not getting location updates when screen goes off. This code is working well till mobile screen goes off.
Please take care its a foreground service.
My Code is as below:

Android Geo-fence not working properly

I am using geofence api for proximity but it is not working properly. some times it gives in range and out range at the same location.
i am also using GPS library to improve accuracy of geofence inrange-outrange but still it is not working properly. i am using below code for geofence :
I am using 300 meters radius for considering inrange-outrange (enter-exit)

Is there anything else we can do to improve accuracy and overcome the problem of inrange outrange at the same location ?

Intent Service getting killed after sometime

I have implemented an intent service in my application, the purpose of which is to monitor the device's shake on a continuous basis.According to the requirement,whenever a shake is detected ,this info should be sent to the app server.
When I started this implementation I had a dilemma on whether to use service or intent service but I chose the latter.Currently,I am able to detect the shake and this info is getting relayed to my app server,but sometimes from 15 min to 2 hour(post starting the app) I notice that this intent service no longer seems to detect any shakes(seems its getting killed on its own).
Here is my code:
public class TheftAlertService1 extends IntentService {
/* The connection to the hardware */
private SensorManager mySensorManager;
/* Here we store the current values of acceleration, one for each axis */
private float xAccel;
private float yAccel;
private float zAccel;
/* And here the previous ones */
private float xPreviousAccel;
private float yPreviousAccel;
private float zPreviousAccel;
private static int SyncRunningFlag = 0;
private double latitude; // latitude
private double longitude; // longitude
/* Used to suppress the first shaking */
private boolean firstUpdate = true;
/* What acceleration difference would we assume as a rapid movement? */
private final float shakeThreshold = .75f;
/* Has a shaking motion been started (one direction) */
private boolean shakeInitiated = false;

SensorManager.SENSOR_DELAY_NORMAL); // (2)
Log.d("TheftAlertService1", "Inside shake onHandleEvent");
}
/* The SensorEventListener lets us wire up to the real hardware events */
private final SensorEventListener mySensorEventListener = new SensorEventListener() {
public void onSensorChanged(SensorEvent se) {
updateAccelParameters(se.values[0], se.values[1], se.values[2]); // (1)

This is what I have tried till now :
1) I have overridden onStartCommand and gave its return as START REDELIVER INTENT
2) I tried to make the intent service in foreground.
But nethier of these two options have 'sustained' the continuous background monitoring of shake on my device.
Following code I tried but in vain:
#Override
public void onCreate() {
super.onCreate();
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
final int myID = 1234;
//The intent to launch when the user clicks the expanded notification
Intent intentService = new Intent(this, Staff.class);
intentService.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendIntent = PendingIntent.getActivity(this, 0, intentService, 0);
//This constructor is deprecated. Use Notification.Builder instead
Notification notice = new Notification(R.drawable.ic_launcher, "Ticker text", System.currentTimeMillis());
//This method is deprecated. Use Notification.Builder instead.
notice.setLatestEventInfo(this, "Title text", "Content text", pendIntent);
notice.flags |= Notification.FLAG_NO_CLEAR;
startForeground(myID, notice);
return START_REDELIVER_INTENT;
}
#Override
public void onDestroy() {
super.onDestroy();
Log.d("TheftAlertService1","Service got killed");
}
What is it that I am doing wrong? What should I do to make my intent service to run continuously in the background(and sense shakes forever).
Any help is appreciated.Thanks !

As Pankaj Kumar suggested I created my shake detection inside a service instead of an IntentService (as I was trying before,which used to fail to detect the shakes after sometime).I tested my service for 48 hours straight on devices(like nexus4,galaxy grand) and was able to detect shakes for the above tested period whenever the device was shaked.
To make the service live indefinitely I made the service foreground and returned START_STICKY as shown below.Following is the full code:
public class ShakeService extends Service {
/* The connection to the hardware */
private SensorManager mySensorManager;
/* Here we store the current values of acceleration, one for each axis */
private float xAccel;
private float yAccel;
private float zAccel;
/* And here the previous ones */
private float xPreviousAccel;
private float yPreviousAccel;
private float zPreviousAccel;
/* Used to suppress the first shaking */
private boolean firstUpdate = true;
/* What acceleration difference would we assume as a rapid movement? */
private final float shakeThreshold = .75f;
/* Has a shaking motion been started (one direction) */
private boolean shakeInitiated = false;
