Webpage not opening in webview

My Code:
String myURL = "https://google.com/";
myWebView = (WebView) findViewById(R.id.webV) ;
WebSettings mywebS= myWebView.getSettings();
mywebS.setJavaScriptEnabled(true);
myWebView.loadUrl(myURL);
it is always asking me permission to open in the system browser.

You must have to add permisssion for internet in manifest file
myWebView.loadUrl("https://www.google.com/");
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
myWebView.loadUrl(request.getUrl().toString());
return false;
}
});
here setting up a webview client is required

The Easiest way is:
myWebView.setWebViewClient(new WebViewClient());
Add this line.

Android WebView doesnt load certain website

mWebView = (WebView) findViewById(R.id.webview_m);
progressBar = (ProgressBar) findViewById(R.id.progressBar1);
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
});
mWebView.loadUrl(url);
above code work fine when loading website like :
google.com
html5test.com
blogspot
and other normal website, but when i try to load url like:
http://sipp.pn-sanggau.go.id/
http://sipp.pn-bandung.go.id/
it doesnt work (not load in my activity), why does this happen?

Add below lines in your code.
webView.setWebChromeClient(new WebChromeClient() );
webView.getSettings().setPluginState(PluginState.ON);

Android Webview is not showing pop up window

I need in-app browser to hit a URL and authenticate a user,that website pop up a window (on all other browser), but it is not showing pop up on the WebView.
This is my code
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
webView.loadUrl(url);
return true;
}
});

As stated in this issue at Google Code, you should use WebChromeClient within your webview.
WebView wv=new WebView(this);
wv.setWebChromeClient(new WebChromeClient());

How to remove or disable WebView header?

I'm trying to remove the webview header, I've tried a number of possible solutions but to no avail.
One of my attempts:
android:theme="#android:style/Theme.NoTitleBar"
I'm loading the webview using this code:
setContentView(R.layout.activity_websitenew1);
WebView myWebView = (WebView) findViewById(R.id.webView1);
myWebView.loadUrl("http://www.domain.com");
myWebView .setWebViewClient(new WebViewClient());
myWebView.getSettings().setJavaScriptEnabled(true);

What is happening in your case is that the URL is being handled by Android which is choosing the handler for you. This handler is the system's browser application. What you want is for control to stay within your app.
You can do this in code as follows:
WebView myWebView = (WebView) findViewById(R.id.webView1);
myWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.loadUrl("http://www.domain.com");
See http://developer.android.com/reference/android/webkit/WebViewClient.html#shouldOverrideUrlLoading(android.webkit.WebView,%20java.lang.String) for details.

Android WebView - code that can display and play a podcast can't play a YouTube video

I have this code which works to display a WebView and use it:
WebView webview = null;
#Override
public void onCreate(Bundle savedInstanceState)
{
//setTheme(R.style.Theme_Sherlock_Light);
super.onCreate(savedInstanceState);
//setContentView(R.layout.podcasts);
webview = new WebView(this);
webview.getSettings().setAppCacheEnabled(false);
webview.getSettings().setJavaScriptEnabled(true);
webview.setInitialScale(1);
webview.getSettings().setPluginState(PluginState.ON);
webview.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
//webSettings.setBuiltInZoomControls(true);
WebSettings webSettings = webview.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setBuiltInZoomControls(true);
//webSettings.getMediaPlaybackRequiresUserGesture();
webSettings.setAllowContentAccess(true);
webSettings.setEnableSmoothTransition(true);
webSettings.setLoadsImagesAutomatically(true);
webSettings.setLoadWithOverviewMode(true);
webSettings.setSupportZoom(true);
webSettings.setUseWideViewPort(true);
setContentView(webview);
webview.loadUrl("url_to_go_to");
But when I try to use this code to point to a YouTube channel, it just shows a blank screen.
Any idea why that would happen?
Thanks!

In order to get HTML5 videos to show up you need to enable the following things in the WebView:
WebView view;
... //initialize WebView
WebSettings webViewSettings = view.getSettings();
view.setWebChromeClient(new WebChromeClient(){}); //just added this
webViewSettings.setDomStorageEnabled(true);
webViewSettings.setAppCacheEnabled(true);
webViewSettings.setAppCachePath(getApplicationContext().getFilesDir().getAbsolutePath() + "/cache");
webViewSettings.setDatabaseEnabled(true);
webViewSettings.setDatabasePath(getApplicationContext().getFilesDir().getAbsolutePath() + "/databases");
You also need to put android:hardwareAccelerated="true" in your AndroidManifest. Otherwise, HTML5 stuff like YouTube videos won't work.
