Implemented methods are not working in native interface(android) for Fused location provider - codenameone

Question

I'm trying to apply FusedLocation provider in cn1 through native interface(android). I've implemented ConnectionCallbacks and OnConnectionFailedListener interfaces. It generates methods like onConnected(), onConnectionSuspended() and onConnectionFailed() in native android, which are not working when app is built in cn1.
Moreover, lifecycle methods like onResume, onDestroy of FusedLocationImpl etc are also not working. In the coming days, I'm planning to create the fused GPS library for general purpose as well.
PS. There are no build errors and got no any other errors when debugged.
FusedLocationImpl.java

import android.os.Bundle;

public boolean isSupported() {
return true;
}

if (!com.codename1.impl.android.AndroidNativeUtil.checkForPermission(Manifest.permission.ACCESS_FINE_LOCATION, "Please allow location permission")) {
}

buildGoogleApiClient();

Log.i("onLocationResult",locationResult + "");
}
#Override
public void onLocationAvailability(LocationAvailability locationAvailability) {
Log.i("onLocationAvailability", "onLocationAvailability: isLocationAvailable = " + locationAvailability.isLocationAvailable());
}
}, null);
}
public void onConnectionSuspended(int i) {
mGoogleApiClient.connect();
}
public void onConnectionFailed(ConnectionResult result) {
Log.i("onConnectionFailed", "Connection failed: ConnectionResult.getErrorCode() = "
+ result.getErrorCode());
}
public void onPause() {
if (mGoogleApiClient.isConnected()) {
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, (LocationListener) this);
mGoogleApiClient.disconnect();
}
}
public void onResume() {
checkPlayServices();
}
public void onStart() {
if (mGoogleApiClient != null) {
mGoogleApiClient.connect();
Log.i("onStart", "mGoogleApiClient.connect()");
}
}
public void onDestroy() {
Log.i("onDestory", "Service destroyed!");
mGoogleApiClient.disconnect();
}
private boolean checkPlayServices() {
int resultCode = GooglePlayServicesUtil
.isGooglePlayServicesAvailable(AndroidNativeUtil.getActivity());
if (resultCode != ConnectionResult.SUCCESS) {
if (GooglePlayServicesUtil.isUserRecoverableError(resultCode)) {
GooglePlayServicesUtil.getErrorDialog(resultCode, AndroidNativeUtil.getActivity(),
PLAY_SERVICES_RESOLUTION_REQUEST).show();
} else {
AndroidNativeUtil.getActivity().finish();
}
return false;
}
return true;
}
protected synchronized void buildGoogleApiClient() {
Log.i("buildGoogleApiClient", "Building GoogleApiClient");
mGoogleApiClient = new GoogleApiClient.Builder(AndroidNativeUtil.getActivity())
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
}
FusedLocation.java
public interface FusedLocation extends NativeInterface{
public void getFusedLocationPermission();
public void fusedLocation();
}
MyApplication.java
public void start() {
if (current != null) {
current.show();
return;
}
Form hi = new Form("Hi World", BoxLayout.y());
hi.show();
Button btn = new Button("ask for permission");
FusedLocation fl = (FusedLocation) NativeLookup.create(FusedLocation.class);
Button btn1 = new Button("fused network");
hi.add(btn1);
btn1.addActionListener(e->{
if (fl != null && fl.isSupported()) {
fl.getFusedLocationPermission();
fl.fusedLocation();
System.out.println("fusedLocation");
}
});
}
PS. permission for location (ACCESS_FINE_LOCATION) succeeds. The main issue I've got is onConnected() and other implemented methods are not called. Thankyou
cn1 Location manager: this is not giving quite a performance as the native fused location provider
public final void checkGPS() {
if (Display.getInstance().getLocationManager().isGPSDetectionSupported()) {
if (Display.getInstance().getLocationManager().isGPSEnabled()) {
InfiniteProgress ip = new InfiniteProgress();
final Dialog ipDlg = ip.showInifiniteBlocking();
//Cancel after 20 seconds
Location loc = LocationManager.getLocationManager().getCurrentLocationSync(20000);
ipDlg.dispose();
if (loc != null) {
lat = loc.getLatitude();
lng = loc.getLongitude();
Dialog.show("location", "lat: " + lat + " lon: " + lng, "ok", null);
} else {
Dialog.show("GPS error", "Your location could not be found, please try going outside for a better GPS signal", "Ok", null);
}
} else {
Dialog.show("GPS disabled", "AppName needs access to GPS. Please enable GPS", "Ok", null);
}
} else {
Dialog.show("Warning", "GPS is not supported in your device", "ok", null);
}
}

I'm not sure why you aren't using the location listener which uses fused location internally when play services is enabled (the default).
You asked for permissions in the XML but didn't use the Android 6+ permissions which need a different syntax. Again, if you just use the location API this is all seamless...
