FusedLocationApi is not working while scheduling it with JobScheduler

问题

Calling FusedLocationApi within jobscheduler doesn't work. I have tried in 2 ways but onConnected() are never called in both of them. How can I make it work? Thankyou

MainActivity.class

public class MainActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnStartJob = (Button)findViewById(R.id.startjob);

        jobScheduler = (JobScheduler)getSystemService(JOB_SCHEDULER_SERVICE);
        btnStartJob.setOnClickListener(new View.OnClickListener(){

            @Override
            public void onClick(View v) {

                ComponentName jobService =
                        new ComponentName(getPackageName(), MyJobService.class.getName());
                PersistableBundle bundle = new PersistableBundle();
                bundle.putString("lat", latitude+"");
                bundle.putString("lon", longitude+"");

                JobInfo jobInfo =
                        new JobInfo.Builder(MYJOBID, jobService).setPeriodic(10000).
                        setRequiredNetworkType(JobInfo.NETWORK_TYPE_ANY).
                        setRequiresCharging(false).
                        setRequiresDeviceIdle(false).
                        setPersisted(true).
                        setExtras(bundle).
                        build();

                int jobId = jobScheduler.schedule(jobInfo);
                if(jobScheduler.schedule(jobInfo)>0){
                }else{
                }
            }
        });
    }
}

Here I have implemented ConnectionCallbacks, OnConnectionFailedListener in JobService but its onConnected() method is never called...

public class MyJobService extends JobService implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener {
    protected JobParameters mJobParameters;
    private GoogleApiClient mGoogleApiClient;
    LocationRequest mLocationRequest;

    public MyJobService() {
    }

    @Override
    public boolean onStartJob(JobParameters jobParameters) {
        Log.e("token", "Start Job Called");
        setUpLocationClientIfNeeded();
        mLocationRequest = LocationRequest.create();
        // Use high accuracy
        mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        mLocationRequest.setInterval(5000);
        return true;
    }

    @Override
    public boolean onStopJob(JobParameters jobParameters) {
        Toast.makeText(this,
                "MyJobService.onStopJob()",
                Toast.LENGTH_SHORT).show();
        return false;
    }

    @Override
    public void onConnected(@Nullable Bundle bundle) {
        if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            return;
        }
        LocationServices.FusedLocationApi.requestLocationUpdates(this.mGoogleApiClient,
                mLocationRequest, this); // This is the changed line.
        Log.e("onConnected", "onConnected");
    }

    @Override
    public void onConnectionSuspended(int i) {

    }

    @Override
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

    }

    private void setUpLocationClientIfNeeded()
    {
        if(mGoogleApiClient == null)
            buildGoogleApiClient();
    }

    protected synchronized void buildGoogleApiClient() {
        this.mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
        this.mGoogleApiClient.connect();
    }

    @Override
    public void onLocationChanged(Location location) {
        Log.e("token",location.getLatitude()+""+location.getLongitude());
    }
}

Called innerClass that implements ConnectionCallbacks, OnConnectionFailedListener in onStartJob of JobService but still onConnected method is never called
