我的网站上有地理位置-我可以用javascript获得位置，但我不能在android设备上使用网络视图获得位置。我使用同一个网站，但它不起作用。
我的网站：https://www.ardakazanci.thecompletewebhosting.com/petsHelper/paylasim.php
我安卓代码：

public class MainActivity extends AppCompatActivity {



        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            WebView webview = (WebView) findViewById(R.id.webview);
            webview.getSettings().setJavaScriptEnabled(true);
            webview.loadUrl("https://www.ardakazanci.thecompletewebhosting.com/petsHelper/paylasim.php");
        }
    }

它在网络上工作得很好。不能与WebView一起工作。谢谢。
错误：
地理位置服务失败
