Connection detector returns false through background service

Question

In my application I want to get GPS location of through a foregrond service and receiver. every thing is running fine but after two or three successful run. service is not able to detect internet and returns false

here is the code

Code for receiver of calling service in activity

public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Intent ll24 = new Intent(getBaseContext(), AlarmReceiver.class);
    PendingIntent recurringLl24 = PendingIntent.getBroadcast(getBaseContext(), 0, ll24, PendingIntent.FLAG_CANCEL_CURRENT);
    AlarmManager alarms = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    alarms.setRepeating(AlarmManager.RTC_WAKEUP,0, 30*10*100, recurringLl24);
   }
 //.....
}

& in receiver class

public class AlarmReceiver extends WakefulBroadcastReceiver 
{   
    static Context context;
    Date curTime,sdf,edf;
    private static final String LOG_TAG = "ForegroundService";

    @Override
    public void onReceive(Context context, Intent intent) 
    {
        try 
        {
            Calendar c =  Calendar.getInstance();
            curTime =  new SimpleDateFormat( "HH:mm" ).parse(c.get( Calendar.HOUR_OF_DAY)+":"+c.get( Calendar.MINUTE));
            sdf = new SimpleDateFormat( "HH:mm" ).parse("08:00");
            edf = new SimpleDateFormat( "HH:mm" ).parse("20:00");    
            if(curTime.after(sdf) && curTime.before(edf))
            {
                Intent ll24Service = new Intent(context, ForegroundService.class);
                ll24Service.setAction(Constants.ACTION.STARTFOREGROUND_ACTION);
                ForegroundService.IS_SERVICE_RUNNING = true;
                startWakefulService(context,ll24Service);   
            }
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
 }

in service class

public class ForegroundService extends Service 
{
...
@Override
public int onStartCommand(Intent intent, int flags, int startId) 
{
    AlarmReceiver.completeWakefulIntent(intent);
    if (intent.getAction().equals(Constants.ACTION.STARTFOREGROUND_ACTION)) 
    {
        Log.i(LOG_TAG, "Received Start Foreground Intent ");
        showNotification();

        Calendar c =  Calendar.getInstance();
        curDateTime  = c.get( Calendar.YEAR)+"-"+ String.valueOf(c.get( Calendar.MONTH )+1)+"-"+ c.get( Calendar.DAY_OF_MONTH)+" "+c.get( Calendar.HOUR_OF_DAY)+":"+c.get( Calendar.MINUTE)+":"+c.get( Calendar.SECOND);

        gps = new GPS(ForegroundService.this);
        if(gps.canGetLocation())
        {
            double latitude = gps.getLatitude();
            double longitude = gps.getLongitude();
            latt=Double.toString(latitude);
            longi =String.valueOf(longitude);

            insertData();   
        }
        else
        {
            gps.showSettingsAlert();
        }   
    } 

@Override
public void onDestroy() {
    super.onDestroy();
    Log.i(LOG_TAG, "In onDestroy");
}

private void insertData() 
{
    try
    {
        String QUERY = "insert into GpsLoc values('"+usr+"','"+latt+"','"+longi+"','"+curDateTime+"')";
        myDatabase.execSQL(QUERY);

        Log.i(LOG_TAG, "insert");
        ConnectionDetector cd = new ConnectionDetector(getApplicationContext());
        Boolean isInternetPresent = cd.isConnectingToInternet();

        if(isInternetPresent)
        {
            Log.i(LOG_TAG, "chk int");
            addToJason();
        }
        else
        {
            Log.i(LOG_TAG, "No int");
            stopForeground(true);
            stopSelf();
        }



    }
    catch(Exception ex)
    {
        Toast.makeText(getApplicationContext(), "Data not inserted : "+ex.toString(), Toast.LENGTH_LONG).show();
    }
}

Every thing is running fine as shown in the log:

03-19 12:11:48.160: I/ForegroundService(17476): Received Start Foreground Intent

03-19 12:11:48.270: D/Network(17476): Network

03-19 12:11:48.340: I/ForegroundService(17476): insert

03-19 12:11:48.390: I/ForegroundService(17476): chk int

03-19 12:11:49.340: I/ForegroundService(17476): uploaded

03-19 12:11:49.350: I/ForegroundService(17476): In onDestroy

But after two or three run same log became

03-19 12:15:34.670: I/ForegroundService(17476): Received Start Foreground Intent

03-19 12:15:34.740: D/Network(17476): Network

03-19 12:15:34.780: I/ForegroundService(17476): insert

03-19 12:15:34.780: I/ForegroundService(17476): No int

03-19 12:15:34.850: I/ForegroundService(17476): In onDestroy

the problem is at checking internet connection while app is not running and it is called through service. Please suggest any solution

Some times it throuws :

03-27 12:30:07.240: I/ForegroundService(1543): android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application

and some times : Error converting result jsonobject

Please help Problem Strat Here when we called to detect internet in service

ConnectionDetector cd = new ConnectionDetector(getApplicationContext());
Boolean isInternetPresent = cd.isConnectingToInternet();

Use FirebaseJobDispatcher. – Paras Watts Mar 19 '18 at 06:59 — Paras Watts, Mar 19 '18 at 06:59

Add this dependency in your gradle file.

compile 'com.firebase:firebase-jobdispatcher:0.8.5'

Create a Firebase JobService File and declare in manifest.

<service
        android:exported="false"
        android:name="._User_Classes.User_Call_Record.ScheduledJobService">
        <intent-filter>
        <action android:name="com.firebase.jobdispatcher.ACTION_EXECUTE"/>
        </intent-filter>
        </service>

Declare and start the JobService from your activity or fragment

FirebaseJobDispatcher dispatcher = new FirebaseJobDispatcher(new GooglePlayDriver(this));
        Job myJob = dispatcher.newJobBuilder()
                .setService(ScheduledJobService.class) // the JobService that will be called
                .setRecurring(false) //repeat the job or not

                .setRetryStrategy(RetryStrategy.DEFAULT_EXPONENTIAL)
                .setTrigger(Trigger.executionWindow(0, 60))
                .setLifetime(Lifetime.FOREVER)
                .setTag("demo")        // uniquely identifies the job
                .build();
        dispatcher.mustSchedule(myJob);

Below is the JobService class which will be called each time the job is executed.

public class ScheduledJobService extends JobService {

    @Override
    public boolean onStartJob(JobParameters job) {
    if(isConnected(this))
{
//internet available
}
else{
//internet not available
}
       //perform your operations
        FirebaseJobDispatcher dispatcher = new FirebaseJobDispatcher(new 
        GooglePlayDriver(this));
        Job myJob = dispatcher.newJobBuilder()
                .setService(ScheduledJobService.class) // the JobService that will be called
                .setRecurring(false) //repeat the job or not
                .setRetryStrategy(RetryStrategy.DEFAULT_EXPONENTIAL)
                .setTrigger(Trigger.executionWindow(0, 60))
                .setLifetime(Lifetime.FOREVER)
                .setTag("demo")        // uniquely identifies the job
                .build();
        dispatcher.mustSchedule(myJob);
        return true;
    }






    @Override
    public boolean onStopJob(JobParameters job) {
        return false;
    }

 public static NetworkInfo getNetworkInfo(Context context) {
        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        return cm.getActiveNetworkInfo();
    }

    /**
     * Check if there is any connectivity
     *
     * @param context
     * @return
     */
    public static boolean isConnected(Context context) {
        NetworkInfo info = getNetworkInfo(context);
        return (info != null && info.isConnected());
    }

}

I hope it helps

Thanks for your reply but I am working in eclipse. i will try to change with this code in eclipse. If you can send me how to implement this in eclipse will help me lot – Kamleshwer Purohit Mar 22 '18 at 11:05
Code does not change whether you use eclipse or android studio – Paras Watts Mar 22 '18 at 11:09
what to about this compile 'com.firebase:firebase-jobdispatcher:0.8.5' – Kamleshwer Purohit Mar 23 '18 at 05:02
I am not aware of how to add dependencies in the eclipse project. You can check some other thread about adding dependencies. – Paras Watts Mar 23 '18 at 05:17
I tried a lot but finally i am not able to add dependency in eclipse. – Kamleshwer Purohit Mar 23 '18 at 06:55
Can't you migrate to android studio ? – Paras Watts Mar 23 '18 at 07:00
Not working Same error is showing even it is not even run after two or three attempt – Kamleshwer Purohit Mar 23 '18 at 09:55
Have you been able to run this in eclipse ? – Paras Watts Mar 23 '18 at 10:11
No i tried this in android studio but it is not running continuously – Kamleshwer Purohit Mar 23 '18 at 10:12
You can set recurring to false and then in start job method again start the new job the same way you are doing in activity, I also do this way in my application , I again set the same job from startJobMethod, I am editing my answer – Paras Watts Mar 23 '18 at 10:14
Check the log problem is remain after two or three run it gives 03-23 16:37:56.668 31322-31322/track.gps.lipi.mygpstrack I/GpsJob: latt 03-23 16:37:56.668 31322-31322/track.gps.lipi.mygpstrack I/GpsJob: usr 03-23 16:37:56.698 31322-31322/track.gps.lipi.mygpstrack I/GpsJob: insert 03-23 16:37:56.718 31322-31322/track.gps.lipi.mygpstrack I/GpsJob: No int – Kamleshwer Purohit Mar 23 '18 at 11:16
Problem is not with running a job problem is detection of internet which is not resolving – Kamleshwer Purohit Mar 23 '18 at 11:18
remove the constraint from the code , then it will run on any network whether connected or not, then in the service check for internet availability – Paras Watts Mar 23 '18 at 11:20
same log is coming no change – Kamleshwer Purohit Mar 23 '18 at 11:29
