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" >
I am not sure why, but now it works. There is code for simply app with webView which use gps location.
MainActivity:
package com.qiteq.gpswebview;
import android.Manifest;
import android.os.Bundle;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AppCompatActivity;
import android.webkit.GeolocationPermissions;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
WebView wv = new WebView(this);
wv.loadUrl("http://qiteq.pl/stack/index.html");
setContentView(wv);
ActivityCompat.requestPermissions(this, new String[]{
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_COARSE_LOCATION
}, 0);
wv.getSettings().setJavaScriptEnabled(true);
wv.setWebChromeClient(new WebChromeClient() {
@Override
public void onGeolocationPermissionsShowPrompt(String origin, GeolocationPermissions.Callback callback) {
callback.invoke(origin, true, false);
}
});
}
}
Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.qiteq.gpswebview">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
And index.html:
<script>
function getLocationConstant()
{
if(navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(onGeoSuccess,onGeoError);
} else {
alert("No GPS support");
}
}
function onGeoSuccess(event)
{
document.getElementById("location").value = event.coords.latitude+", "+event.coords.longitude;
alert("Success: "+event.coords.latitude+", "+event.coords.longitude);
}
function onGeoError(event)
{
alert("Error code " + event.code + ". " + event.message);
}
</script>
<input type="text" name="location" id="location" style="width:278px;">
<button onclick="getLocationConstant()" >Click</button>
