I have a simple APP that calls a HTTPS page and latitude and longitude don't work when calling https://www.mypage.com/getlonlat.html from within my APP. It works when calling page from IE, Chrome, Firefox ect. getlonlat.html has javascript that uses GeoLocation to calculate longitude and latitude. This page HAS a valid SSL.

document.getElementById("getlon").value = position.coords.longitude;
}

As it turns out, my SSL certificate was not set up properly with my hosting company. The code above works perfectly now. How nifty, call a HTML, PHP, JAVA page from an APP without having to re-write the whole page in android.

I am trying to auth google user in WebView, I found a good solution for these days, it works fine for google login, but I cannot disable dialog in other urls like (, sms: , smsto:)
Example Situation: User click on telephone number in my app, it will open the phone dial, but when he returns back.. there is a empty dialog window with close button, i use it for google login with JS.
How can i close this dialog message inside the shouldOverrideUrlLoading()? Or is there any better solution to not open other links in the dialog? How can i improve my code to solve my problem? Thank you guys!

I am new to android, recently I developed an application which runs on WebView means in my activity I placed a webview doing the gamin activity through html,js pages by loading those to webview.
Here my request is "How to load the Interstitial Ads from the webpage files(html,js) I googled most of the suggestions related to Ionic App but my app is AndroidStudio related.
so please help
Loading an ad from WebView isn't that straightforward but could be done. So let's take the following example:
class MainActivity extends AppCompatActivity {
protected InterstitialAd mInterstitialAd;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// load interstitial ad
mInterstitialAd = new InterstitialAd(getContext());
mInterstitialAd.setAdUnitId("YOUR_AD_ID");
mInterstitialAd.loadAd(new AdRequest.Builder().build());
WebView browser = findViewById(R.id.webview);
browser.addJavascriptInterface(new InterceptorJavaScript(context), "Interceptor");
WebSettings webSettings = browser.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setDomStorageEnabled(true);
browser.setWebViewClient(new CapturingWebViewClient());
browser.loadUrl("http://website.com");
}
/**
* This class will handle all JS events from the UI back to
* Java code and will trigger the Interstitial ad
*/
private class InterceptorJavaScript {
Context webViewContext;
/**
* Instantiate the interface and set the context
*/
InterceptorJavaScript(Context webView) {
webViewContext = webView;
}
#JavascriptInterface
#SuppressWarnings("unused")
public void startInterstitial() {
// we need to run it on the main UI thread
Handler mHandler = new Handler(Looper.getMainLooper());
mHandler.post(new Runnable() {
#Override
public void run() {
if (MainActivity.mInterstitialAd.isLoaded()) {
MainActivity.mInterstitialAd.show();
}
// preload new ad
BrowserFragment.mInterstitialAd.loadAd(new AdRequest.Builder().build());
}
});
}
}
private class CapturingWebViewClient extends WebViewClient {
/**
* This method will inject the JavaScritp that will trigger
* your Java code and show the interstitial in the main UI thread
*/
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
view.loadUrl(
"javascript:Interceptor.startInterstitial();"
);
// Attach JS event to your button so you can call the JS function. I've used jQuery just for simplicity
view.loadUrl(
"javascript:$('#btn').on('click', function(){ Interceptor.startInterstitial(); });"
);
}
}
}

Basically My question is HOW CAN I POSSIBLY PUT THESE TWO CODES TOGETHER TO FUNCTION PROPERLY!!! this is killing my trying to figure it out so i'll explain in deep detail...Any help would be much appreciated!!!
i have a webpage at http://s-ka-paidbeats.com/app_tree/ourotherapps it lists a bunch of apps i have made in google play.in the webpage html i have them listed with standard links like - https://play.google.com/store/apps/details?id=com.yesorno.app.yesorno
i've created a tab in ALL the android applaications that i've made called "My Other Apps"this tab is a webview window that shows the same html page i was talking about above- http://s-ka-paidbeats.com/app_tree/ourotherapps
the problem is when a user visits the webview window in any of my android applications and clicks on any of the apps i have listed on the html webpage (https://play.google.com/store/apps/details?id=) it takes them to google play in the webview window and asks them to login to google play in the webview window (even if they are already logged in to google play on their device)... this is extremely ugly and annoying for users to face.
i want to make it so when a user visits the "my other apps" tab in any of my applications, and clicks on one of the apps in the webview window it opens the actual google play application (if google play is installed) or opens in the default browser installed on the device (if google play is not installed)
i have tried to change all the (https://play.google.com/store/apps/details?id=) links to (market://details?id=) links on the html page and then visited the webview window again in my app however this time when i click on any of the apps listed i just get a page error "page does not exist" window
i have looked into setWebViewClient and i am sure that there is someway to do this using something like the code posted below
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getScheme().equals("market")) {
try {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
Activity host = (Activity) view.getContext();
host.startActivity(intent);
return true;
} catch (ActivityNotFoundException e) {
// Google Play app is not installed, you may want to open the app store link
Uri uri = Uri.parse(url);
view.loadUrl("http://play.google.com/store/apps/" + uri.getHost() + "?" + uri.getQuery());
return false;
}
}
return false;
} });
I tried adding the code above to my current code but now my loading dialog box wont close when the webview is loading.... it just stays loading forever.... so i took the code snippet above out of my code again because i dont think i am placing it in the right place or that i am integrating the two codes together properly....
i noticed my current code already has a setWebViewClient defined so im not sure if im allowed to have two in the same code or if i am suppose to try and combine it with the current one....... I HAVE NO CLUE where to begin and i have been reading for hours....
Here is my current code

i have tried to change all the (https://play.google.com/store/apps/details?id=) links to (market://details?id=) links on the html page
Don't do that. Use the google play URLs you started with.
i noticed my current code already has a setWebViewClient defined so im not sure if im allowed to have two in the same code or if i am suppose to try and combine it with the current one
You combine them. You create one WebViewClient to handle all the needs of one WebView. It's not difficult:
webView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
if (dialog.isShowing()) {
dialog.dismiss();
}
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// is this a play store URL?
String partialUrl = "/store/apps/details?id=";
if (url.contains(partialUrl)) {
// extract the app id from the URL
int pos = url.indexOf(partialUrl) + partialUrl.length();
String appId = url.substring(pos);
try {
// open the google play app
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=" + appId));
OtherApps.this.startActivity(intent);
return true; // we overrode the url load
} catch (ActivityNotFoundException e) {
// no google play app, load URL in device browser
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
OtherApps.this.startActivity(intent);
return true;
}
}
return false; // no override, let the webview load this url
}
});
for anyone looking for the answer to this... here is the correct code
webView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
if (dialog.isShowing()) {
dialog.dismiss();
}
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// is this a play store URL?
String partialUrl = "/store/apps/details?id=";
if (url.contains(partialUrl)) {
// extract the app id from the URL
int pos = url.indexOf(partialUrl) + partialUrl.length();
String appId = url.substring(pos);
try {
// open the google play app
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=" + appId));
OtherApps.this.startActivity(intent);
return true; // we overrode the url load
} catch (ActivityNotFoundException e) {
// no google play app, load URL in device browser
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));

return true;

I am developing android web application for a blog like website.
For this I am showing HTML page contenting list of categories which when clicked shows articles related to that category.
I am fetching this articles from website's RSS feeds which is in XML format and by using JavaScript I am parsing it to display on HTML page.
This process of parsing XML takes lot of time to load a page.During this period I am getting blank screen.I have implemented progress dialog which works fine when page is loading for the first time but when XML is getting parsed by JavaScript it does not appear.
Here is how I implemented Process dialog.
Activity.java:
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.main);
getWindow().setFeatureInt(Window.FEATURE_PROGRESS,
Window.PROGRESS_VISIBILITY_ON);
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.setBackgroundColor(0);
final ProgressDialog progressDialog = new ProgressDialog(activity);
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressDialog.setMessage("Loading...please wait");
progressDialog.setCancelable(true);
webview.setWebViewClient(new WebViewClient()
{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
});
webview.loadUrl("file:///android_asset/HomePage.html");
// WebChromeClient give progress etc info
webview.setWebChromeClient(new WebChromeClient()
{
public void onProgressChanged(WebView view, int progress)
{
progressDialog.show();
progressDialog.setProgress(0);
activity.setProgress(progress * 1000);
progressDialog.incrementProgressBy(progress);
if (progress == 100 && progressDialog.isShowing())
progressDialog.dismiss();
}
});
}
How can I show progress dialog while XML is being parsed by JavaScript?
Also I want to show an error message if no internet connectivity available for same thing is their any way to do so?
I have used call function as "tel:phone number" which was working but after I added de
public boolean shouldOverrideUrlLoading it is not working? what's i done wrong?

Im trying to invoke a method in java from javascript, but this doesn't happen when I run the application in the emulator, the application stops when it is suppose to call the method in java. here is the java code:
import android.os.Bundle;
import android.webkit.WebView;
import com.phonegap.*;
public class App extends DroidGap {
WebView webView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
webView = new WebView(this);
webView.addJavascriptInterface(new message(), "Show");
super.loadUrl("file:///android_asset/www/index.html");
}
class message {
String msg() {
return "Hello World!!";
}
}
}
here is the javascript:
<script type="text/javascript">
{
alert("Start");
alert(Show.msg());
alert("End");
}
</script>
It shows the first alert but nothing thereafter, can anyone help?
Your problem is that you're half using PhoneGap and half not. You're creating a separate WebView class from PhoneGap's. The WebView class that you added "Show" to never gets used. Instead the WebView class that is a member of the super (DroidGap) is.
You should do one of two things.
Use PhoneGap's plugin structure (see examples here)
Don't use PhoneGap at all and have a class that looks more like the following:
public class act extends Activity {
WebView webView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
webView = new WebView(this);
webView.getSettings().setJavaScriptEnabled(true);
// Set JS alert() hook
webView.setWebChromeClient(new WebChromeClient() {
public boolean onJsAlert(WebView view, String url, String message, JsResult result)
{
return false;
}
});
webView.loadUrl("file:///android_asset/www/index.html");
// Add JS libraries
webView.addJavascriptInterface(new message(), "Show");
}
class message {
public String msg() {
return "Hello World!!";
}
}
}
Note that the method msg needs to be public
Why not just use AlertDialog?
private void showDialog(int title, String message) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(title);
builder.setMessage(message);
builder.setPositiveButton(R.string.ok_button, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
builder.show();
}
