Problem with restoring webview state after app installation

I have a simple android app with WebView which opens the site main page. I need to save WebView state when the user presses "home" or "main menu" buttons. And then, when user opens app from the homescreen or main menu I need to load this saved state.
Everything works fine except the first launch (after installation of built apk file): if I open app from main menu the WebView restores just fine, but if I try to open it from homescreen it starts to reload. Is there any ways to fix that? Thanks in advance.
P.S. if I install app from Android Studio (not from built apk file) everything works as I expect, so I am confused.
These are methods where I save and restore WebView:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
if (savedInstanceState != null)
webView.restoreState(savedInstanceState);
else
webView.loadUrl(getString(R.string.URL));
}
protected void onSaveInstanceState(Bundle outState)
{
webView.saveState(outState);
super.onSaveInstanceState(outState);
}

Open a link on WebView

I am using WebView on my application.
the WebView contains a web site with link.
When I am clicking on the link, it is open the link on the application(By webView).
How can I open the link with the browser?
Thank you!

Try something like this
new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
or if you need to override Webview link click use this
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
This should do the trick

Android webview - webpage renders in a very broken way

I am trying to load this popular podcast in an Android WebView:
http://www.stitcher.com/podcast/entrepreneuronfirecom/entrepreneur-on-fire-tim-ferriss-other-incredible-entrepreneurs
And this is how I render it:
public class PodcastsActivity extends BaseActivity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
WebView webview = new WebView(this);
webview.getSettings().setAppCacheEnabled(false);
webview.getSettings().setJavaScriptEnabled(true);
webview.setInitialScale(100);
webview.setWebViewClient(new WebViewClient());
setContentView(webview);
webview.loadUrl("http://www.stitcher.com/podcast/entrepreneuronfirecom/entrepreneur-on-fire-tim-ferriss-other-incredible-entrepreneurs");
And in my manifest I have the activity defined like this:
<activity
android:name="PodcastsActivity"
android:label="Podcasts"
android:hardwareAccelerated="true"/>
But it renders like this:
Is there an extra setting that needs to be set? Or something I am missing?
Thanks!

I hope you have looked at other answers. Some of the things you may try are:
1) From webview not loading correctly in application question, you may try and enable java script before loading the URL:
webview.setInitialScale(1);
webview.getSettings().setAppCacheEnabled(false);
webview.getSettings().setJavaScriptEnabled(true);
2) As per Android webview not rendering html content correctly question, if your target is higher than 2.3.3 try adding this in your manifest file.
android:hardwareAccelerated="true"
Update
3) Also check that you have following permission in manifest as direct child to <manifest> tag:
<uses-permission android:name="android.permission.INTERNET" />
Unable to load webpage using WebView in Android
4) You can try shouldOverrideUrlLoading() method as stated here.
Update 2:
As you said that it displays correctly on your browser, there is another possibility of using the above method in case when a certain link is clicked within the app, it opens the default browser. I'm not sure if you would want this but it is a possibility. Something as follows:
webview.setWebViewClient(new WebViewClient(){
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url != null) {
view.getContext().startActivity(
new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
return true;
} else {
return false;
}
}
});
webview.loadUrl("http://www.stitcher.com/podcast/entrepreneuronfirecom/entrepreneur-on-fire-tim-ferriss-other-incredible-entrepreneurs");
Source: WebView link click open default browser
Hope this helps.

Android webview script tag not loading source file

I'm trying to load a javascript file from a script tag in Webview, but it won't load it!
here's the source for the HTML Script tag:
<script type="text/javascript" src="file:///android_asset/game/tetris.js"></script>
And the java file:
WebView webview;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("file:///android_asset/game/tetris.html");
}
I've tried with and without the "file:///android_asset/game/" and it still won't load!
Any ideas? Thanks!

I do the same in my applications with relative paths, and it works fine for me.
In this case I'd simply use src="tetris.js" in the HTML

Web Page Not Available - Loading local HTML on Android

Yo guys, this is bugging me and I can't find a fix for it,
I have a simple activity to launch a WebView and display a HTML file
public class HelpViewer extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.help_page_layout);
WebView browser = (WebView) findViewById(R.id.help_page_webview);
browser.loadUrl("file:///android_asset/help.html/");
}}
The help_page_layout is your standard WebView resting in a LinearLayout - Not problems there.
The help.html is sitting under the /res/raw/ directory. From what I have see online, there shouldn't be a problem here either.
But when the WebView goes to load, it just tells me that the WebPage was not available because help.html couldn't be found.
What am I doing wrong?

This question suggests the file should be in /assets rather than /res/raw. You also have a trailing slash on the end of your URL.
