Android service not restarting in lollipop

Question

In my application, I use location based service in background. So I need to restart my service when it gets destroyed.

But I got this message in logcat

Answer 1

Finally I achieved with help of Evernote JobService

Github link - https://github.com/evernote/android-job

Step 1: Add evernote jobservice dependency

implementation 'com.evernote:android-job:1.3.0-alpha03'

Step 2: Create DemoJobCreator.java class

public class DemoJobCreator implements JobCreator {

@Override
@Nullable
public Job create(@NonNull String tag) {
    switch (tag) {
        case DemoSyncJob.TAG:
            return new DemoSyncJob();
        default:
            return null;
    }
}
}

Step 3: Create DemoSyncJob.java class

public class DemoSyncJob extends Job {

public static final String TAG = ">>>> job_demo_tag";

@Override
@NonNull
protected Result onRunJob(Params params) {
    // run your job here
    Log.d(TAG, "onRunJob: ");
    if(!isMyServiceRunning(this.getContext(), TestService.class)){
        Intent intent=new Intent(context,TestService.class);
        context.startService(intent);
    }
    scheduleJob();
    return Job.Result.SUCCESS;
}

public static void scheduleJob() {
    new JobRequest.Builder(DemoSyncJob.TAG)
            .setExecutionWindow(2_000L, 2_000L)
            //.setPeriodic(900000) -> recommended. but it will work after 15 min (if you used this no need scheduleJob(); inside onRunJob();)
            .build()
            .schedule();
 }

 public static boolean isMyServiceRunning(Context context, Class serviceClass) {
    try {
        ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
            if (serviceClass.getName().equals(service.service.getClassName())) {
                return true;
            }
        }
    }catch (Exception e){
        Log.e(TAG, "isMyServiceRunning: ",e );
    }
    return false;
  }
  }

Step 4: In your Application file (If not available create it) add following line in onCreate()

 JobManager.create(this).addJobCreator(new DemoJobCreator());

Step 5: Finally start JobService in your Activity

DemoSyncJob.scheduleJob();

This JobService will check service running or not (every 2 second) If service not running it will restart the service.

Disclaimer : This may be not right solution. But it will 100% working.

I hope it helps atleast anyone in future.
