I am Trying to implement the horizontal progressbar.But I am not understanding how to implement it in my class.Now I have implemented the dialog box which is in the format of sphener,But I want it in horizontal format showing progress of activity I am downloading some contents at that time it should show the progress.
My code is
public class Loginwebview extends Activity {
WebView webview;
String url1;
Bundle bundle=null;
private ProgressDialog progressDialog;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.weblogin);
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
bundle = new Bundle();
webview.setWebViewClient(new WebViewClient()
{
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
url1=url.toString();
bundle.putString("parameter", url1);
progressDialog = ProgressDialog.show(Loginwebview.this, "", "Loading...");
new Thread() {
public void run() {
try{
if(url1.contains("&mydownloads=true"))
{
if(url1.contains(".zip"))
{
sleep(150000);
Intent i1 = new Intent(Loginwebview.this, DownloadZipActivity.class);
i1.putExtras(bundle);
startActivityForResult(i1,0);
}
else
{
sleep(40000);
Intent i2 = new Intent(Loginwebview.this, DownloadOther.class);
i2.putExtras(bundle);
startActivityForResult(i2, 0);
}
}
else if(url1.contains("mydownloads=true"))
{
Log.d("its in Mydownloadssss",url1.toString());
Intent i3=new Intent(Loginwebview.this,Downloadlist.class);
i3.putExtras(bundle);
startActivityForResult(i3, 0);
}
}
catch(Exception e)
{
}
progressDialog.dismiss();
}
}.start();
return true;
}
public void onPageFinished(WebView view, String url1) {
Log.i("inside onpage", "Finished loading URL: " +url1);
String mainurl=url1;
}
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Log.e("onReceivedError", "Error: " + description);
}
});
webview.loadUrl("http://xxx/PublicModules/UserLoginVerify.aspx?userid=809&deviceid=DA0CE50D-0EEB-5E8E-9DCA-AED00F9BDFE5");

I have problem with reducing the time of displaying progress bar in WebView. For underesting a add image. enter image description here.
Where I can implement some thread of something to stop showing progress bar for one second, while my web running in WebView?
I tried implement thread before showing progress bar in onPageStarted, but it waiting for whole loading page, not only for loading progress bar.
We have very slow loading on web page, so we need showing to users one or two second loading page in webview without progressbar, after this time show "loading" progress bar.
If you have question, please ask me, we need quick respond to resolve this problem. I'm trying to find some solution, but nothing.
Thanks a lot!

Hey bro, you don't necessarily need to implement threads for your
requirement. Firstly you can load the url in the webview and after a
particular time period you can start displaying progress bar. For
calling the progress bar after certain time period you can use
Handler.
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
//Do something after 100ms
prDialog = new ProgressDialog(MainActivity.this);
prDialog.setIcon(R.drawable.icon);
prDialog.setMessage(getString(R.string.nacitani_webove_stranky));
prDialog.show();
}
}, 100);
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
if(prDialog!=null){
prDialog.dismiss();
}
}
I am using WebView for loading a website. But it is very slow and is leaking when specific websites are loaded.
I am loading WebView with the following code.
#Override
protected void onNewIntent(Intent intent) {
if (intent.getStringExtra("url") != null) {
webView.loadurl(intent.getStringExtra("url"));
}
}
But I am calling webView.loadUrl(Config.URL); (Config.URL may contain same url as specified above) in onCreate() method after initializing WebView with the following.
this.webView = (WebView) findViewById(R.id.wv);
this.webView.getSettings().setJavaScriptEnabled(true);
this.webView.getSettings().setLoadsImagesAutomatically(true);
this.webView.getSettings().setDomStorageEnabled(true);
this.webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
MyClient client = new MyClient(WebActivity.this, (ProgressBar)findViewById(R.id.progressBar));
webView.setWebViewClient(client);
Loading a from onCreate() is working fine (not fine, it's too slow). But
the same URL that is loading from onNewIntent() is not working!!!.
After I did this inonNewIntent() no URLs got loaded using
webView.loadurl() and the current page is getting immovable. ie. the
scrollbars are moving in WebView but page is not scrolling. I tested
the same URL in onCreate() and it is working.
For doing that I am passing url with
intent.putExtra("url", Config.URL+targetUrl);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
with the pending intent from the notifications. Although it is working in some devices i.e Google Nexus. But it is not working on most of the phones.
I have

The question is: What is the problem when using loadurl() method in onNewIntent()?
Try this from where you loads webview
web.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return super.shouldOverrideUrlLoading(view, url);
}
});
You can use the webclient to handle the webview. Here I include the javascript with loading.
String aboutURL="YOUR URL";
final ProgressDialog pd = ProgressDialog.show(, "", "Please wait", true);
WebSettings settings=Webview.getSettings();
settings.setJavaScriptEnabled(true);
settings.setAppCacheEnabled(true);
settings.setDomStorageEnabled(true);
settings.setLoadsImagesAutomatically(true);
settings.setDatabaseEnabled(true);
settings.setRenderPriority(WebSettings.RenderPriority.HIGH);
settings.setCacheMode(WebSettings.LOAD_NO_CACHE);
settings.setSupportZoom(true);
settings.setBuiltInZoomControls(true);
Webview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon)
{
pd.show();
}
#Override
public void onPageFinished(WebView view, String url) {
pd.dismiss();
}
});
Webview.loadUrl(aboutURL);
Here Loading is processed based on network
Use Handler to post a delay action as below will fix this, but I don't known why.
new Handler().post(webView.loadurl(url));
I am loading some urls in my app using android WebView and all successful. But when i am trying to load this url:
http://dev.infibond.com/cloud/instagram?user_profile=https%3A%2F%2Fscontent.cdninstagram.com%2Ft51.2885-19%2Fs150x150%2F13534190_829691380497090_1099495058_a.jpg&user_name=infibondtest
But for some reason i am failing - "view.loadUrl(url);" in "shouldOverrideUrlLoading" doesn't show the page and doesn't load another url. just shows a white page.
The response code from the server is 304.
Before i am getting to this url, i am doing authentication with Instagram and sending the access token as a cookie.

I am not 100% sure, but it seems like you have a lot of small errors. I think the one in question is here:
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
handleProgressBarVisibility(url);
String cookieString = WEB_VIEW_TOKEN + "=" +
NetworkManager.instance().getToken();
CookieManager.getInstance().setCookie(mUrl, cookieString);
view.loadUrl(url);
return true;
}
The view.loadUrl(url) seems very wrong to me. I think you may need to change this to something like:
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("dev.infibond.com")) {
return false;
}
// otherwise, they are leaving the site, so open a new
// browser instead
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
And remove the guts of what you did here. Most of it is findViews() and should not be repeated anyway. I'm guessing this is what you meant to do with
handleProgressBarVisibility(url) in the WebViewClient but I'm not really sure:
#Override
public void onLoadResource(WebView view, String url) {
handleProgressBarVisibility(url);
}
I am using webview to display the html data.It is working fine if the data is less(less than 1 mb)..I am using following code
mDecryptDataWv.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
DebugLog.i(TAG, "Processing webview url click...");
view.loadUrl(url);
return true;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
//showProgressDialog();
DebugLog.i(TAG, "************onPageStarted **************");
}
#Override
public void onPageFinished(WebView view, String url) {
DebugLog.i(TAG, "************onPageFinished **************");
if (mProgressDialog != null) {
if (mProgressDialog.isShowing()) {
DebugLog.i(TAG, "mProgressDialog ::::::stopping");
mProgressDialog.dismiss();
mProgressDialog = null;
}
}
If the data is more then 1MB it is taking more time to complete the loading.so my intention is to load the data page by page upon user scrolling with progress dialog..Can anyone has idea?

I have a WebView and I load the page using webView.loadUrl("http://myurl.com") and the page gets shown correct on android 4.X but while trying on 2.X, more specifically 2.3.5 a plain text gets displayed similar to this
What might be the problem and how do I fix it? Thanks!

Things I tried
*Saving the HTML to the assets folder by manually copy and pasting it there and then load the saved HTML works fine. But why cant I load it from the web?
Do like this
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
and then set webview client with your web view like this
web.setWebViewClient(new HelloWebViewClient());
