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());

Click hyperlink on WebView launch other browser app

I use below code to load URLPath in WebView:
WebView webView = (WebView)findViewById(R.id.webview);
String myURL = URLPath;
WebSettings websettings = webView.getSettings();
websettings.setSupportZoom(true);
websettings.setBuiltInZoomControls(true);
websettings.setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl(myURL);
The url page contain hyperlink.
I want to launch other browser app(such as chrome) while click hyperlink.
How can I do it?

Use this code
webView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
if(url.equals("http:\\your.url")
view.loadUrl(url);
else
// Do something here to open link in google chrome or some external browser
return true;
}
});

Android Webview doesn't show contents clearly

In recents, i had a problem with android webview i wanted to play youtube embed video center of the screen but webview had showed me black blank area in right side of video. Now i need to open documents by using Google docs but i have same problem in documents like:
Here is my webview codes:
WebView mWebView = (WebView)findViewById(R.id.webView1);
if (Build.VERSION.SDK_INT < 8) {
mWebView.getSettings().setPluginsEnabled(true);
} else {
mWebView.getSettings().setPluginState(PluginState.ON);
}
mWebView.getSettings().setUseWideViewPort(true);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setLayoutAlgorithm(LayoutAlgorithm.NORMAL);
mWebView.setHorizontalScrollBarEnabled(false);
mWebView.setVerticalScrollBarEnabled(false);
mWebView.getSettings().setDefaultZoom(ZoomDensity.CLOSE);
mWebView.setInitialScale(-20);
mWebView.setWebChromeClient(new WebChromeClient());
mWebView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
//mWebView.loadUrl(" http://docs.google.com/viewer?url=http%3A%2F%2Fresearch.google.com%2Farchive%2Fbigtable-osdi06.pdf");
String pdf = "http://www.projectcounter.org/SSPJune_2007.ppt";
mWebView.loadUrl("http://docs.google.com/gview?embedded=true&url=" + pdf);

Why Android WebChromeClient's onCreateWindow method never got called?

I'm building my app on webview service and trying to open new url in another window (neither in default system browser nor in same webview). I set up my own WebViewClient and WebChromeClient like below,
public class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading (WebView view, String url) {
view.loadUrl(url);
return true;
}
}
public class MyWebChromeClient extends WebChromeClient {
#Override
public boolean onCreateWindow (WebView view, boolean isDialog, boolean isUserGesture, Message resultMsg) {
WebView childView = new WebView(view.getContext());
final WebSettings settings = childView.getSettings();
settings.setJavaScriptEnabled(true);
childView.setWebChromeClient(this);
childView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
WebView.WebViewTransport transport = (WebView.WebViewTransport) resultMsg.obj;
transport.setWebView(childView);
resultMsg.sendToTarget();
Log.d(LOG_TAG, "onCreateWindow"); // never log
return true;
}
}
I also definitely had my webview setSupportMultipleWindows to true.
However, onCreateWindow never got called. Is there anything I missed?
Thanks in advance.

Did you tell the "parent" webview that multiple windows are allowed?
WebView parentWebview = (WebView) findViewById(R.id.parent_webview);
// ...
parentWebview.getSettings().setSupportMultipleWindows(true);
That's the most common mistake I've seen.

add this line to code to invoke onCreateWindow()
webView.getSettings().setSupportMultipleWindows(true);

Without the full code its hard to say why OnCreateWindow() isn't being called. In your activity OnCreate() method do you have code similar to the following?
// Get the main web viewer
mWebView = (WebView) findViewById(R.id.webViewer);
// Enable Javascript
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
// Set WebViewClient and WebChromClient
mWebView.setWebViewClient(new MyWebViewClient());
mWebView.setWebChromeClient(new MyWebChromeClient());
Also, what code are you using in which you think the OnCreateWindow() should be called?
