super.onPageFinished(view, url);
progressBar.setVisibility(View.GONE);
}
}
Where is the error here? please help me im also having problem with adview. here

You've created a custom WebViewClient class but you aren't using it.
Change web.setWebViewClient(new WebViewClient());
to web.setWebViewClient(new webclient());

Change these two methods.
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
progressBar.dismiss();
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
}
Change web.setWebViewClient(new WebViewClient());
to web.setWebViewClient(new webclient());

How To Display Custom "Web Page Not Available" Error Page in WebView

pls help me to display custom Web Page Not Available error page...in webview..i tried many code and when i run the app it shows app has been stopped

You can override onReceivedError callback of WebViewClient to achieve the desired functionality.
Either you can display some dialog to denot your custom message or load the webview with any custom html available locally in your app.

USE this it working fine on my side. May be it will help you
private WebView webviewSites;
String URL="http://www.google.com";
webviewSites = (WebView) findViewById(R.id.webview_sites);
WebSettings webSettings = webviewSites.getSettings();
webSettings.setSupportMultipleWindows(true);
webSettings.setJavaScriptEnabled(true);
webviewSites.setWebViewClient(new myWebClient());
webviewSites.loadUrl(URL);
public class myWebClient extends WebViewClient {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(final WebView view, final String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
// mProgressBar.setVisibility(View.GONE);
Log.i("LOAD_URL", "" + url);
}

Show activity circle before loading webview - Android

I am using webview to show a webpage in my app. The webpage takes about 2-3 seconds to load.
Till the webpage loads, I want to show an activity circle progress bar like the one shown here. This is what an activity circle looks like :
How can I accomplish it?
I searched the web but couldn't find a satisfactory and proper explanation of how it is implemented. Thanks!
WebViewPage.java
public class Webpage extends Activity {
WebView web;
ProgressBar progressBar;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.web_page);
Intent startwebpage = getIntent();
web = (WebView) findViewById(R.id.webView);
web.setWebViewClient(new myWebClient());
web.getSettings().setJavaScriptEnabled(true);
web.loadUrl("http://www.google.com");
}
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
}
}
}

Display progressBar in onPageStarted method and dismiss it in onPageFinished.
private ProgressDialog progressBar;
Show progressBar in onPageStarted:
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
// prepare for a progress bar dialog
progressBar = new ProgressDialog(v.getContext());
progressBar.setCancelable(true);
progress.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progressBar.show();
}
2.Dismiss it in onPageFinished:
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
progressBar.dismiss();
}
EDIT : Use ProgressBar instead of ProgressDialog.
Use Following code in your layout.
Use drawable of your choice for "#drawable/progress"
<ProgressBar
android:id="#+id/progress_bar"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:visibility="gone"
android:indeterminateDrawable="#drawable/progress" >
</ProgressBar>
Inflate it in your activity. Make it visible in onPageStarted and gone in onPageFinished.
private ProgressBar prgrsBar;
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
prgrsBar.setVisibility(View.VISIBLE);
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
prgrsBar.setVisibility(View.GONE);
}

This works for me:
ProgressDialog pb = null;
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
// prepare for a progress bar dialog
if (pb == null) {
pb = new ProgressDialog(Quiz.this);
pb.setCancelable(true);
pb.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pb.show();
}
}
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
pb.dismiss();
}
