HMS FusedLocationProvider and HuaweiMap is not working

Question

I used this class to get current location of device for my map app. I'm using this with GooglePlayServices and its working fine, but I recently switched to HMS for Huawei devices if GooglePlayServices are not available on device. I replaced all GooglePlayServices classes with mirror objects from HMS imported lib and it compiled without errors. But as I call for current location, it will not return anything. No exception, no success or failure.

I did not receive callback to onLocationResult() or catch() block. According to debugger last row called is val task = lp.requestLocationUpdates(lr, this, Looper.getMainLooper())

Anyone has this problem? This is clearly new issue. Testing this on Huawei P40 where GooglePlayServices are not available.

Also HuaweiMap is not working in release mode. getMapAsync() will not return onMapReady() callback. It got stuck there. But if I switch debug mode, it is working correctly.

UDPATE: HuaweiMap is working now. Updated proguard. But Location is still not working. It is not working even in debug mode.

Code:

private inner class LocationCbHua(val lp: com.huawei.hms.location.FusedLocationProviderClient,
                                      val onFailure: (()->Unit)? = null,
                                      val onSuccess: (GpsLocation)->Unit)
        : com.huawei.hms.location.LocationCallback() {

        init {
            val lr = com.huawei.hms.location.LocationRequest.create().apply {
                priority = com.huawei.hms.location.LocationRequest.PRIORITY_HIGH_ACCURACY
                interval = 200
            }
            val lsr = com.huawei.hms.location.LocationSettingsRequest.Builder().run {
//                setAlwaysShow(true)  // TEST
                addLocationRequest(lr)
                build()
            }
            val check = com.huawei.hms.location.LocationServices.getSettingsClient(activity!!).checkLocationSettings(lsr)
            check.addOnCompleteListener {
                try {
                    check.getResultThrowException(com.huawei.hms.common.ApiException::class.java)
                    val task = lp.requestLocationUpdates(lr, this, Looper.getMainLooper())
                    task.addOnFailureListener {
                        onFailure?.invoke()
                    }
                } catch (e: com.huawei.hms.common.ApiException) {
                    when (e.statusCode) {
                        com.huawei.hms.location.LocationSettingsStatusCodes.RESOLUTION_REQUIRED-> if(!locationResolutionAsked){
                            // Location settings are not satisfied. But could be fixed by showing the user a dialog.
                            try {
                                // Cast to a resolvable exception.
                                val re = e as com.huawei.hms.common.ResolvableApiException
                                // Show the dialog by calling startResolutionForResult(), and check the result in onActivityResult().
                                re.startResolutionForResult(mainActivity, MainActivity.REQUEST_LOCATION_SETTINGS)
                                locationResolutionAsked = true
                            } catch (e: Exception) {
                                e.printStackTrace()
                            }
                        }
                        com.huawei.hms.location.LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE->{
                            // Location settings are not satisfied. However, we have no way to fix the settings so we won't show the dialog.
                            App.warn("Location is not available")
                            onFailure?.invoke()
                        }
                    }
                }
            }
        }

        fun cancel(){
            lp.removeLocationUpdates(this)
            currLocCb = null
        }

        override fun onLocationResult(lr: com.huawei.hms.location.LocationResult) {
            cancel()
            val ll = lr.lastLocation
            onSuccess(GpsLocation(ll.longitude, ll.latitude))
        }
    }

Answer 1

The possible cause is as follows:

After checkLocationSettings code was executed, an exception was catched during execution of code check.getResultThrowException. However, the catched error code is not 6 (RESOULTION_REQUIRED).

Therefore, code com.huawei.hms.location.LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE was directly executed to report Location is not available after code com.huawei.hms.location.LocationSettingsStatusCodes.RESOLUTION_REQUIRED-> if(!locationResolutionAsked) was executed.

As a result, neither exception nor location result was obtained. You are advised to add a code line at when (e.statusCode) to record error logs, and then continue error analysis.

Answer 2

Use OnSuccessListener instead of OnCompleteListener

   val check = com.huawei.hms.location.LocationServices.getSettingsClient(activity!!).checkLocationSettings(lsr)
   check.addOnSuccessListener{
       lp.requestLocationUpdates(lr, this, Looper.getMainLooper())
   }
