Javascript on Android WebView not working

I have some issues with Android WebView and Javascript.
Some of customers of app said that WebView on app is not showing anything.
As I checked - its probably not showing javascript at all (whole webpage is loaded in javascript by react).
That my code:
public void setupWebView(WebView accessWebView) {
accessWebView.setWebViewClient(new WebViewClient() {
#SuppressWarnings("deprecation")
#Override
public boolean shouldOverrideUrlLoading(WebView webView, String url) {
handleRedirect(accessWebView);
return true;
}
});
accessWebView.getSettings().setJavaScriptEnabled(true);
accessWebView.getSettings().setDomStorageEnabled(true);
accessWebView.loadUrl(URL);
(I have to use WebViewClient, not WebChromeClient, because of the redirect handling)
Is there anything possible to change so the javascript will load on EVERY device with Android +5.0?
Is it possible that updating WebView on device will help some users?

You need to use setWebChromeClient to enable javascript in your WebView. But don't worry, you can use both setWebChromeClient and setWebViewClient in the same time. Just like in official docs:
// Let's display the progress in the activity title bar, like the
// browser app does.
getWindow().requestFeature(Window.FEATURE_PROGRESS);
webview.getSettings().setJavaScriptEnabled(true);
final Activity activity = this;
webview.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
// Activities and WebViews measure progress with different scales.
// The progress meter will automatically disappear when we reach 100%
activity.setProgress(progress * 1000);
}
});
webview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();
}
});
webview.loadUrl("https://developer.android.com/");

How to use webview to open url just like UCBrowser

I am new in android. I am trying to make just a sample application to open websites in webview. The problem is, website opens in desktop mode. How can I open websites just like UCBrowser (mobile mode) ?

Try this. It should work.
webview1.getSettings().setJavaScriptEnabled(true);
webview1.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(getApplicationContext(), description, Toast.LENGTH_SHORT).show();
}
});
webview1.getSettings().setLoadWithOverviewMode(true);
webview1.getSettings().setUseWideViewPort(true);
webview1.getSettings().setBuiltInZoomControls(true);
webview1 .loadUrl("http://www.matrixsystems.net.in/"); // set url
webview1.requestFocus();

Webview doesn't show a specific website

I'm trying to do a webview based application for this website to show it in a mobile application.
when I put any different site the application work great, but in this specific site never show the second page when I clicked in the button to go to the desk page. However, I put a Log statement in the onPageFinished method and log that the page is loaded completely.
My Code Here
final WebView myWebView = (WebView) rootView.findViewById(R.id.webview);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.setWebViewClient(new WebViewClient() {
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(getActivity(), "Oh no! " + description, Toast.LENGTH_SHORT).show();
}
#Override
public void onPageFinished(WebView view, String url) {
Log.d("WEBSITE", "Page Loaded.");
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Log.d("WEBSITE", url);
myWebView.loadUrl(url);
return false;
}
});
myWebView.loadUrl("https://demo.frappecloud.com/");

I believe the problem is with your shouldOverrideUrlLoading. If you check the documentation you will see that :
This method is not called for requests using the POST "method"
When you are submitting the Form, you are making a POST request, which is basically ignored.
Here is the link: WebViewClient
Also check this reference where it says how you could load a URL with POST data: LOAD A POST REQUEST INTO A WEBVIEW IN ANDROID
Consider checking this thread: Android - how to intercept a form POST

How to set the WebChromeClient to open the new page in the same view?

I load the url in the WebView but, when the user click some button the new url is loaded in the android browser not in my webview. What should I do?
Thanks in advance.

You have to use both WebViewClient and WebChromeClient.
WebChromeClient allows you to get loading progress, for example, whereas WebViewClient will allow you overriding shouldOverrideUrlLoading().
From the WebView page doc:
webview.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
// Activities and WebViews measure progress with different scales.
// The progress meter will automatically disappear when we reach 100%
activity.setProgress(progress * 1000);
}
});
webview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();
}
});

webchromeClient does not seem to have this ability. Seems silly that WebViewClient can and WebChromeClient can't.

just go through
http://developer.android.com/reference/android/webkit/WebView.html
you will come to know how to use webchromeClient.....
tell me if this help for you...

Android how to pass google account to webview

I am using webview to show google canlender but want to pass google account programmatic-ally,so the setHttpAuthUsernamePassword() function should be what I need but it doesn't work at all. Here is the code:
WebView webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.setHttpAuthUsernamePassword("www.google.com", "", "email", "password");
webview.setWebViewClient(new WebViewClient() {
#Override
public void onReceivedHttpAuthRequest (WebView view, HttpAuthHandler handler, String host,String realm){
handler.proceed("email","password");
}
}
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
});
webview.loadUrl("http://www.google.com/calendar/");
If you have any idea to make this worked, please let me know. I tried to search a lot but don't see any useful.

You're trying to use HTTP authentication (http://en.wikipedia.org/wiki/Basic_access_authentication) which is not supported by most web services. You need to have valid Google cookies, which are set only when you manually sign in with your password.
