WPS office take the html opened file from chrome when pressing a link

I am saving the offline docs of android development in my SD and I am opening them with chrome and when I press any link it takes me to WPS office even do not asking I tried clear defaults but nothing changed

I have the same question, just add this function in your code:
webView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url!=""){
view.loadUrl(url);
System.out.println("url:"+url);
}
return true;
}
});

Trying to autoplay YouTube video in a PhoneGap/Cordova app

I'm developing an app using PhoneGap. So, it's a web app. In this app, I have a requirement to embed a YouTube video and autoplay it whenever the user navigates to that particular page.
I've read that HTML5 video autoplay doesn't work on mobile devices because of bandwidth concers. My question is that is there any way at all to bypass this restriction? I don't mind complex workarounds or hacks that could allow me to do this. Anything at all.
Thanks.

As you pointed out yourself, all autoplay instructions in your code itself will be ignored on load. So we'll implement a function that gets the video in the body and starts playing it.
The following javascript code could do this:
(function() {
document.getElementsByTagName('video')[0].play();
})()
To execute this code after the page has loaded, we need to set a WebViewClient and implement onPageFinished()
webview.setWebViewClient(new CordovaWebViewClient(this, webview) {
// autoplay when finished loading via javascript injection
public void onPageFinished(WebView view, String url) { webview.loadUrl("javascript:(function() { document.getElementsByTagName('video')[0].play(); })()"); }
});
final WebSettings settings = webview.getSettings();
settings.setJavaScriptEnabled(true);
settings.setJavaScriptCanOpenWindowsAutomatically(true);
settings.setPluginState(WebSettings.PluginState.ON);
A full example:
webview = new CordovaWebView(this);
setContentView(webview);
final WebSettings settings = webview.getSettings();
settings.setJavaScriptEnabled(true);
settings.setJavaScriptCanOpenWindowsAutomatically(true);
settings.setPluginState(WebSettings.PluginState.ON);
webview.setWebViewClient(new CordovaWebViewClient() {
// autoplay when finished loading via javascript injection
public void onPageFinished(WebView view, String url) { webview.loadUrl("javascript:(function() { document.getElementsByTagName('video')[0].play(); })()"); }
});
webview.loadUrl("http://html5demos.com/video");

There is a cordova/phonegap plugin that promises to do this. It rely on the Webview method setMediaPlaybackRequiresUserGesture, added in API level 17 (Android 4.2).
It simply call this method on the webview:
WebView view = getWebViewFromPlugin();
view.getSettings().setMediaPlaybackRequiresUserGesture(false);
It's also available in phongap build.

Is there a way to hide addressbar in webchromeclient?

I am developing an android application in which I want to show a website, which have links in it. When any link is clicked, then it plays an online stream.
Till now I have developed an app which work alright. In this I have used webview to display first screen. The live stream is not supported in webview, so I used webchromeclient.
Now the problem is when any link is clicked, a new browser opens and plays the stream and also shows the address bar and address of page loaded page.
I want to hide the address of new loaded page.
and if possible, also I wnt to keep webchromeclient in existing screen, not a new browser.

in this case you have to customize the WebViewClient like this
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// This is my web site, so do not override; let my WebView load the page
return true;
}
}
}
Then create an instance of this new WebViewClient for the WebView:
WebView myWebView = (WebView) findViewById(R.id.webview);
myWebView.setWebViewClient(new MyWebViewClient());
for further have a look on this, and read carefully

How do I open another app in my WebView app?

I have an Android app with that displays a mobile website (WebView), in the mobile website there are links redirecting to a PDF, Excel and video files.
When try to open it in my regular browser my phone asks to open it with another app or it start a download, so I can open it afterwards.
But in my WebView app it either doesn't work, no response or it displays a "Page unavailable" error.
Is it even possible?

To handle links in WebView, you can use the shouldOverrideUrlLoading method of WebViewClient class. Consider the following example;
WebView webView = (WebView) findViewById(R.id.infoView);
webView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// Assuming you are giving link to some PDF file.
if (url.contains(".pdf")) {
// Now do what you want to with the url here
}
return true;
}
}
This way, you can intercept any link tapped in WebView and then do whatever you want.

webview not loading urls, but it will load data

I'm using standard addresses like google and facebook, but loadUrl does nothing, it just sits there at a white screen, but if i pipe html into it using loadData, it works fine. Any ideas or tips? I've got it enabling javascript, and I have this call:
mWebView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
TextView t;
t = (TextView)findViewById(R.id.pageTitle);
t.setText(view.getTitle());
}
});
Do i need to override anyhting else?

Check whether you have enabled INTERNET permission in Android manifest file.
