Andorid webview - Remember user credentioal while a link open in browser

I have a webView online shop.
for some security reason I have to force my webView application to open payment page in user's default browser. I leave my code below for more information. but when that specific page open in browser it could not detect users credential and other important data like order number and etc.
How do I proceed to solve this?
Thank You All In Advance.
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// open in Webview
if (url.contains("https://example.com/checkout/confirmpaymentorder") ){
// if (Uri.parse(url).getHost().equals(getString(R.string.myhost)))
return false;
}
// open rest of URLS in default browser
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}

Facebook share button in Android Application

FB share button could successfully oepn the FB messenger app in Chrome browser.
However, the same source code, it fail to open the FB messenger app if display in Android APP application, and this application display web page using Chrome browser inside.
How to fix it?

You could provide a custom WebViewClient implementation to your WebView that checks for facebook.com links (or whatever links you like) and then explicitly fire an Intent so others can pickup the Action, instead of allowing the WebView to handle it as it sees fit.
webview.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
try {
Uri uri = Uri.parse(url);
if (uri.getHost().contains("facebook.com")) {
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
return false;
}
} catch(Exception e){
e.printStackTrace();
}
return super.shouldOverrideUrlLoading(view, url);
}
});

Display a pdf with dynamic generating url in WebView / Google Docs

so I just started with Android programming and I am trying to make a little app using WebView. There is a url that redirects you to a pdf, I know WebView does not render pdf. So I want to use intent and display the pdf in Google Docs. However, the pdf address is randomly generated so I cant link it with
WebView.loadUrl("http://docs.google.com/gview?embedded=true&url=" + pdfURL);
How can I send an intent to Google Docs without using the exact pdf address?

I don't know what "randomly generated" means.
But the first thing that comes to my mind is to set a WebViewClient and override shouldOverrideUrlLoading:
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.endsWith(".pdf") == true) {
view.loadUrl("http://docs.google.com/gview?embedded=true&url=" + url);
return true;
}
return false;
}
});

Open Soundcloud URL in native Soundcloud app from WebView

Scenario
I have a WebView in my Android app which contains a Soundcloud embed (from Embedly). This embed has two buttons: "Play on Soundcloud" and "Listen in browser".
The "Play on Soundcloud" button contains a URL in format intent://tracks:257659076#Intent;scheme=soundcloud;package=com.soundcloud.android;end
Code
My WebView uses a custom WebViewClient (because I need to intercept some URLs for some different stuff).
protected class WebViewClient extends android.webkit.WebViewClient {
public WebViewClient() { }
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
PackageManager packageManager = context.getPackageManager();
// Create an Intent from the URL.
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
// Find out if I have any activities which will handle the URL.
List<ResolveInfo> resolveInfoList = packageManager.queryIntentActivities(intent, 0);
// If we have an app installed that can handle the URL, then use it.
if (resolveInfoList != null && resolveInfoList.size() > 0) {
Intent viewUrlIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
context.startActivity(viewUrlIntent);
}
else {
// Do something else.
}
return true;
}
}
Problem
Clicking "Listen in browser" plays the track in the embed itself and works fine. Clicking "Play on Soundcloud" will call into shouldOverrideUrlLoading in the WebViewClient above (as expected). However, my code to find a activity can't find anything that can deal with this Soundcloud URL.
If I don't set my WebViewClient on the WebView (so it just does its own thing), the "Play on Soundcloud" button will work as expected and launch the Soundcloud app.
Temporary (crap) solution
I've managed to make this do what I want it to do by parsing the URL to get the track ID, then building a new URL using a format that Soundcloud definitely accepts (thanks to this SO post). A URL in the format "soundcloud://tracks:[TRACK_ID]" will be accepted by the Soundcloud app.
But WHY?
Either I am doing the whole "find out what activities can handle this URL" thing wrong, or maybe(?!) the default WebViewClient used by the WebView handles this explicitly?! Seems implausible.

I'm just extending the Temporary (crap) solution here, so this is far from a perfect answer, but might still help someone who absolutely needs to get this to work, also with private tracks.
The replace method works if the track is public, but with private tracks this does not work, probably because of the missing secret token in the intent URL.
Unfortunately the embed player does not contain all the necessary pieces of the URL I need to generate, except inside the iframe, which I cannot access due to cross-origin policy. So in addition to the iframe code I also need the share link.
What I ended up doing is making sure that the containing HTML page has the share link as a JS variable. I then read that variable using Java and create a new Intent with that URL. This works, because the official app also registers all soundcloud.com URLs.
So for private tracks this goes to the HTML page:
<script>var soundCloudURL = "https://soundcloud.com/my-profile/my-track/my-secret-token";</script>
Then inside your Android app you would have something like this:
#Override
public boolean shouldOverrideUrlLoading (WebView view, String url) {
if (uri.getScheme().contains("intent")) {
openSoundCloudPlayer();
return true;
}
}
private void openSoundCloudPlayer() {
appWebView.evaluateJavascript("(function() { return soundCloudUrl })();", new ValueCallback<String>() {
#Override
public void onReceiveValue(String soundCloudUrl) {
// JS null is converted into a string "null", not Java null.
if (soundCloudUrl != "null") {
// Take out the quotes from the string
soundCloudUrl = soundCloudUrl.replace("\"", "");
Uri newUri = Uri.parse(soundCloudUrl);
Intent intent = new Intent(Intent.ACTION_VIEW, newUri);
startActivity(intent);
}
}
});
}

Android Studio Webview open link directly on Google Play

I have a Web App that loads locally html.
In one html, I have a link to a Google Play app, but the link opens inside the app, inside the webview.
On iOS devices any link https://itunes.apple.com/app/id000 will automatically open iTunes/App Store on the devices.
Is there a way to open the Google Play app directly from an html?
I'm trying _blank or the market:// as suggested on other questions, but nothing works.
App Link
App Link 2
Thanks!

you can use this it will work
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;
}});
maybe this will help any one
