Android模拟器Geocoder grpc在上使用JobIntentService失败

问题描述

我正在进行位置选择器活动，以检索“标记”位置（使用onCameraIdleListener）并使用Geocoder getFromLocation（）生成地址信息。在真实设备上运行正常。

长话短说，我阅读了有关此问题的所有其他主题，并且确实实现了自定义JobIntentService来解决此问题。但是奇怪的是，在我的仿真器（Pixel 3a XL API 26）上，它似乎在首次尝试调用getFromLocation（）时成功检索了地址信息，但随后的所有尝试均引发IOException grpc失败。

我尝试根据以下答案使用JobIntentService：https://stackoverflow.com/a/62140756/12338956

class FetchAddressJobIntentService:JobIntentService()
{
    private val tag = "ADDRESS_SERVICE"

    private var resultReceiver: ResultReceiver? = null

    /*
    override fun onHandleWork(intent: Intent) {
        onHandleIntent(intent)
    }*/

    override fun onHandleWork(intent: Intent) {
        var errorMessage = ""

        resultReceiver = intent.getParcelableExtra(RECEIVER)

        //Checks if receiver was properly registered
        //MainActivity must pass the receiver as bundle extra
        if (resultReceiver == null) {
            Log.wtf(tag,"No receiver received. There is nowhere to send the results")
            return
        }
        //Get the location passed to this service through an extra.

        val location: Location? = intent.getParcelableExtra(LOCATION_DATA_EXTRA)

        //Make sure the location is really sent
        if (location == null) {
            errorMessage = "no location data provided"
            Log.wtf(tag,errorMessage)
            deliverResultToReceiver()
            return
        }
        //Setting locale
        val geocoder = Geocoder(this,Locale.ROOT)
        //Address found

        Log.e(tag,location.toString())

        var addresses: List<Address>? = null
        try {
            addresses = geocoder.getFromLocation(location.latitude,location.longitude,1)
        } catch (ioException: IOException) { //Catches network or i/o problems
            errorMessage = "service not available"
            Log.e(tag,errorMessage,ioException)
        } catch (illegalArgumentException: IllegalArgumentException) { //Error in latitude or longitude data
            errorMessage = "invalid latitude or longitude"
            Log.e(
                    tag,errorMessage + ". Latitude = " + location.latitude +
                            ",Longitude = " + location.longitude,illegalArgumentException
            )
        }
        //Handles cases where no addresses where found
        if (addresses == null || addresses.isEmpty()) {
            if (errorMessage.isEmpty()) {
                errorMessage = "no address found"
                Log.e(tag,errorMessage)
            }
            deliverResultToReceiver()
        } else {
            val address = addresses[0]
            deliverAddressToReceiver(address)
        }
    }

    private fun deliverAddressToReceiver(
            address: Address
    ){
        val bundle = Bundle()
        bundle.putParcelable(ADDRESS,address)
        resultReceiver?.send(SUCCESS_ADDRESS,bundle)
    }

    private fun deliverResultToReceiver() {
        val bundle = Bundle()
        bundle.putString(RESULT_DATA_KEY,"1")
        resultReceiver!!.send(FAILURE_RESULT,bundle)
    }


    companion object
    {
        @JvmStatic
        fun enqueueWork(mapsActivity: MapsActivity,intent: Intent)
        {
            enqueueWork(mapsActivity,FetchAddressJobIntentService::class.java,1,intent)
        }
    }
}

在我的MapsActivity onCreate（）中：

addressResultReceiver = new AddressResultReceiver(new Handler(Looper.getMainLooper()));

 if (fusedLocationProviderClient != null)
            fusedLocationProviderClient.getLastLocation().addOnSuccessListener(this,location -> {
                // Got last known location. In some rare situations this can be null.
                if (location != null) {
                    currentLocation = location;
                    currentLatLng = new LatLng(currentLocation.getLatitude(),currentLocation.getLongitude());
                    map.animateCamera(CameraUpdateFactory.newLatLngZoom(currentLatLng,15));
                }
            });

AddressResultReceiver类：

private class AddressResultReceiver extends ResultReceiver
    {
        AddressResultReceiver(Handler handler)
        {
            super(handler);
        }
        //Receives data sent from FetchAddressJobIntentService and updates the UI in MainActivity.
        @Override
        protected void onReceiveResult(int resultCode,Bundle resultData)
        {
            if (resultCode == SUCCESS_ADDRESS)
            {
                Address a = resultData.getParcelable(ADDRESS);
                if (a != null)
                    markerUserLocation = new UserLocation("Marker Location",a);
            }
        }
    }

在相机空闲时开始意图：

GoogleMap.OnCameraIdleListener onCameraIdleListener = () -> {

            LatLng latLng = map.getCameraPosition().target;
            markerLocation = new Location("Camera Location");
            markerLocation.setLatitude(latLng.latitude);
            markerLocation.setLongitude(latLng.longitude);

            Intent intent = new Intent(this,FetchAddressJobIntentService.class);
            intent.putExtra(RECEIVER,addressResultReceiver);

            //pass the marker location
            intent.putExtra(LOCATION_DATA_EXTRA,markerLocation);
            FetchAddressJobIntentService.enqueueWork(MapsActivity.this,intent);
        };
        map.setOnCameraIdleListener(onCameraIdleListener);
        map.setOnCameraMoveStartedListener(onCameraMoveStartedListener);

它在应用程序首次在模拟器上运行时成功检索了地址信息，但抛出IOException：当我更改相机（标记）位置时，grpc失败。我尝试重新启动应用程序和模拟器但它仍然仅在应用启动时起作用。

Logcat在应用启动并显示地址时未显示错误

在我拖动摄像机后，Logcat显示从onHandleWork（）抛出的grpc异常

我100％确信应用启动时从意图服务返回了地址信息，并且直到onReceiveResult（）才初始化“ markerLocation”。

有什么想法吗？

更新：我以某种方式通过在模拟器上打开飞行模式来修复它... 打开飞行模式并打开wifi，现在当我拖动相机时，它正在更新地址。

在这一点上，我很确定这是一个模拟器问题。但是，如果有可能是代码问题，欢迎任何帮助/想法/解释。
