package com.example.user.myGPS;

    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.content.IntentSender;

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

        //-------Code to turn on GPS------------------
        if (googleApiClient == null) {

            googleApiClient = new GoogleApiClient.Builder(MainActivity.this)
                    .addApi(LocationServices.API).build();
            googleApiClient.connect();
            LocationRequest locationRequest = LocationRequest.create();
            locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
            locationRequest.setInterval(30 * 1000);
            locationRequest.setFastestInterval(5 * 1000);
            LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);
            builder.setAlwaysShow(true);
            builder.setNeedBle(true);


            PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
            result.setResultCallback(new ResultCallback<LocationSettingsResult>() {

                    final LocationSettingsStates state = result.getLocationSettingsStates();
                    switch (status.getStatusCode()) {
                        case LocationSettingsStatusCodes.SUCCESS:
                            break;
                        case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                            try
                            {
                                status.startResolutionForResult(MainActivity.this,REQUEST_CHECK_SETTINGS);
                            } catch (IntentSender.SendIntentException e) {}
