PermissionUtils can not be resolved

I'm trying to get my current location in my app but I'm getting PermissionUtils error. This isn't getting resolved. I got the codes from google's official github tutorial.

PermissionUtils

public class MapsActivity extends FragmentActivity implements GoogleMap.OnMyLocationButtonClickListener,
GoogleMap.OnMyLocationClickListener,
OnMapReadyCallback,
ActivityCompat.OnRequestPermissionsResultCallback

/**
* Request code for location permission request.
*
* @see #onRequestPermissionsResult(int, String, int)
*/
private static final int LOCATION_PERMISSION_REQUEST_CODE = 1;

/**
* Flag indicating whether a requested permission has been denied after returning in
* @link #onRequestPermissionsResult(int, String, int).
*/
private boolean mPermissionDenied = false;

private GoogleMap mMap;

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

SupportMapFragment mapFragment =
(SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);




@Override
public void onMapReady(GoogleMap googleMap)
mMap = googleMap;

mMap.setOnMyLocationButtonClickListener(this);
mMap.setOnMyLocationClickListener(this);
enableMyLocation();



private void enableMyLocation()


if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED)
// Permission to access the location is missing.
PermissionUtils.requestPermission(this, LOCATION_PERMISSION_REQUEST_CODE,
Manifest.permission.ACCESS_FINE_LOCATION, true);
else if (mMap != null)
// Access to the location has been granted to the app.
mMap.setMyLocationEnabled(true);




@Override
public boolean onMyLocationButtonClick()
Toast.makeText(this, "MyLocation button clicked", Toast.LENGTH_SHORT).show();
// Return false so that we don't consume the event and the default behavior still occurs
// (the camera animates to the user's current position).
return false;


@Override
public void onMyLocationClick(@NonNull Location location)
Toast.makeText(this, "Current location:n" + location, Toast.LENGTH_LONG).show();


@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String permissions,
@NonNull int grantResults)

if (requestCode != LOCATION_PERMISSION_REQUEST_CODE)
return;


if (PermissionUtils.isPermissionGranted(permissions, grantResults,
Manifest.permission.ACCESS_FINE_LOCATION))
// Enable the my location layer if the permission has been granted.
enableMyLocation();
else
// Display the missing permission error dialog when the fragments resume.
mPermissionDenied = true;



@Override
protected void onResumeFragments()
super.onResumeFragments();
if (mPermissionDenied)
// Permission was not granted, display error dialog.
showMissingPermissionError();
mPermissionDenied = false;



/**
* Displays a dialog with error message explaining that the location permission is missing.
*/
private void showMissingPermissionError()
PermissionUtils.PermissionDeniedDialog
.newInstance(true).show(getSupportFragmentManager(), "dialog");

Do you had set uses permission in manifest? If don't, you should set it first.

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>


PermissionUtils is a class defined by the sample project. If you want to use it, you'll have to copy it to your project.
