From This Activtiy I called the service
But as soon as remove my application from recent apps through swipe the location listener stops working and does not show any location change update but if the app is running then it works fine.
public class Dashboard extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dashboard);
Intent l = new Intent(getApplicationContext(),LocationService.class);
getApplicationContext().startService(l);
}
Do you stop service in onDestroy of your activity ?
You could also override method onStartCommand and use START_STICKY value.
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.i(TAG, "Received start id " + startId + ": " + intent);
// We want this service to continue running until it is explicitly
// stopped, so return sticky.
return START_STICKY;
}
UPDATE1
You could start your service in a separate process. See doc :
http://developer.android.com/guide/topics/manifest/service-element.html#proc
If the process name begins with a lowercase character, the service
will run in a global process of that name, provided that it has
permission to do so.
for instance:
<service
android:name=".LocationService"
android:process="myLocationService" [...] >
[...]
</service>

What i am doing wrong .
Use Pending Intent to get LocationUpdates using service upto android 7.0 above use you have to use Broadcast receiver:
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent != null) {
final String action = intent.getAction();
if (ACTION_PROCESS_UPDATES.equals(action)) {
LocationResult result = LocationResult.extractResult(intent);
if (result != null) {
List<Location> locations = result.getLocations();
Log.d("servicelocation","*******lastupdate "+result.getLastLocation());
Log.d("servicelocation","******* "+locations.size()+
"\n"+locations.get(locations.size()-1).getLatitude() +" " +
"lng "+locations.get(locations.size()-1).getLongitude());
Toast.makeText(getApplicationContext(),"Service Stared "+locations.size(),Toast.LENGTH_SHORT).show();
}
}
}else {
Log.d("serviceintentvalues","********");
}
return START_STICKY;
}

I want to do something like this:
When my application starts I want to start a Service which should check my location
When the application goes to background I want to stop the service
I have two major problems:
How can I detect that my application goes to background? I haver several activities, and I tried that in my MainActivity overriding onPause, but the onPause is also called when I start an other activity.
This problem is more important: How should my Service which checks for my location look like? I tried several approaches, but no success.
My Service looks like this, and it's not working. What should I change to make it work?
package com.pivoscore.service;
import android.app.Service;
import android.content.Context;
import android.content.Intent;

but don't forget to Add the permission i've added in comment
and also don't forget to added service tag in manifest File

Application is not a visual component in Android. It is divided into Activities, each of them run when visible, paused and destroyed otherwise. So, there is no concept of whole Application going to background, Activities are paused and resumed on the basis of their individual visibility and are completely independent of other Activities in this matter.
Your Service shall register with Location Manager in its onCreate(), unregister from the same in its onDestroy(). In its onBind() it shall return a Messenger object. And, in onLocationChanged() it should send a message through its shared Messenger. No need to use START_STICKY as you don't want Service running all the time.
The Activity (can be any activity in the App) just needs to call bindService() in its onStart(), The service will start if not already, and Activity will get a Messenger from service. Also, Activity should call unbindService() from its onStop(). The Service will automatically stop when nothing is bound to it.
If you need to do the stuff in point 3 at App (Task) level, implement the Application class, and use its onCreate() and onTerminate(). Application class is not paused or stopped like an Activity.
I suggest you to use the latest location api provided by google(also compatible to version 2.2).
here is a example shows how to use that:
https://github.com/chenjishi/android_location_demo
when your app run to background, you can call disconnect to stop the location update.
Try This code.. By using this you can find whether your application is in foreground or background. Hope this will help you.
try {
foreground = new ForegroundCheckTask().execute(ctx).get();
}
======================================
class ForegroundCheckTask extends AsyncTask<Context, Void, Boolean> {
#Override
protected Boolean doInBackground(Context... params) {
final Context context = params[0].getApplicationContext();
return isAppOnForeground(context);
}
private boolean isAppOnForeground(Context context) {

.getSystemService(Context.ACTIVITY_SERVICE);
List<RunningAppProcessInfo> appProcesses = activityManager
.getRunningAppProcesses();
if (appProcesses == null) {
return false;
}

String activePackageName = activityManager.getRunningTasks(1).get(0).topActivity.getPackageName();

return true;

Try Puuting things that you want to do inside run of this class,
This thread runs every 5 Seconds,
You can modify it as you want.
public class PeriodicChecker extends Thread
{
#Override
public void run()

while(true) {
System.out.println("Thread is doing something");
//Put Your code here
Thread.sleep(5000);
}
}
}
public OtherClass {
public static void main(String args[]) {
Thread t = new PeriodicChecker();
t.start();
}
}
What I'm attempting to do is when receiving a c2dm message, start a service that asks for location for 'x' amount of time and then hands that location off to our server. The c2dm message starts the service correctly, and the GPS location turns on, but it never updates. It just sits there for the length of time I specify (currently 12 seconds) in the thread and does nothing. I'm using the exact same code somewhere else in my app (not as a service) and it works perfectly. What am I doing wrong?
This starts the service when receiving a c2dm message.
context.startService(new Intent(context, ServicePingLocation.class));
This is the code for the service itself. All that ever gets called, is "onCreate" and "onStart".

[Edit]
Fixed the issue I was having. Code was actually working. I added the network provider, adjusted the onDestroy() method to stop the service, and tweaked the time used to grab GPS signal.
Thank you for the advice, CommonsWare
