I am trying to create WebView which would get GPS localization via js, but when i click on button which should show localization: in android 4.1.1(emulator): "Error code 2. Failed to start Geolocation service in android 4.1.2(phone) just nothing happens in android 6.0(emulator) the same, just nothing happens

My permissions:

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

My settings:

webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setGeolocationEnabled(true);
        webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        webView.getSettings().setBuiltInZoomControls(true);

        webView.getSettings().setSaveFormData(false);
        webView.getSettings().setSavePassword(false);
        webView.getSettings().setAppCacheEnabled(true);
        webView.getSettings().setDatabaseEnabled(true);
        webView.getSettings().setDomStorageEnabled(true);
        webView.getSettings().setGeolocationDatabasePath(getFilesDir().getPath());

WebChromeClient:

WebChromeClient webChromeClient = new WebChromeClient(){

            @Override
            public void onGeolocationPermissionsShowPrompt(String origin, GeolocationPermissions.Callback callback) {
                // callback.invoke(String origin, boolean allow, boolean remember);
                callback.invoke(origin, true, false);
            }

            public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture){
                mUploadMessage = uploadMsg;
                Intent i = new Intent(Intent.ACTION_GET_CONTENT);
                i.addCategory(Intent.CATEGORY_OPENABLE);
                i.setType("*/*");
                MainActivity.this.startActivityForResult(Intent.createChooser(i, "File Chooser"), MainActivity.FILECHOOSER_RESULTCODE);

            }

            public boolean onShowFileChooser (WebView webView, ValueCallback<Uri[]> filePathCallback, WebChromeClient.FileChooserParams fileChooserParams){
                Intent i = new Intent(Intent.ACTION_GET_CONTENT);
                i.addCategory(Intent.CATEGORY_OPENABLE);
                i.setType("*/*");
                MainActivity.this.startActivityForResult(Intent.createChooser(i, "File Chooser"), MainActivity.FILECHOOSER_RESULTCODE);
                return false;
            }

        };

WebViewClient:

WebViewClient webViewClient = new WebViewClient(){
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url){
                view.loadUrl(url);
                return true;
            }

            public void onPageFinished(WebView view, String url){
                progressBar.setVisibility(View.GONE);
                webView.setVisibility(View.VISIBLE);
                refreshBtn.setVisibility(View.VISIBLE);
            }
        };

at the end, i have this line of code:

ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, 0);

and js code (not my code):

    <script>
function getLocationConstant()
{
  if(navigator.geolocation)
  {
   navigator.geolocation.getCurrentPosition(onGeoSuccess,onGeoError);
  } else {
   alert("Brak obsługi GPS");
  }
}


function onGeoSuccess(event)
{
  document.getElementById("skad").value =  event.coords.latitude+", "+event.coords.longitude;
 document.getElementById('szk').click();

}


function onGeoError(event)
{
  alert("Error code " + event.code + ". " + event.message);
}


</script>

<input type="text" name="skad" style="width:278px;" id="skad" >

check this code function so good, its necesary for sdk >4 implements the next, join with requestpermisision.

@Override
        public void onGeolocationPermissionsShowPrompt(final String origin, final GeolocationPermissions.Callback callback) {
            //Log.i(TAG, "onGeolocationPermissionsShowPrompt()");

            final boolean remember = true;
            AlertDialog.Builder builder = new AlertDialog.Builder(vistamaps.this);
            builder.setTitle("Locations");
            builder.setMessage("Would like to use your Current Location ")
                    .setCancelable(true).setPositiveButton("Allow", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    // origin, allow, remember
                    callback.invoke(origin, true, remember);
                    int result = ContextCompat.checkSelfPermission(getBaseContext(), Manifest.permission.ACCESS_COARSE_LOCATION);
                    if (result == PackageManager.PERMISSION_GRANTED) {

                    } else {
                        ActivityCompat.requestPermissions(vistamaps.this, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION}, 101);
                    }
                }
            }).setNegativeButton("Don't Allow", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    // origin, allow, remember
                    callback.invoke(origin, false, remember);
                }
            });
            AlertDialog alert = builder.create();
            alert.show();
        }
