How can I refresh both the page and it's content in android webview?
Just reload the url will do what you want.
either mWebView.reload() or mWebView.loadUrl(URL) is fine.

I have a simple Activity to show a webview and a back button. Here is the code that I use to load the URL that I want in the webview.
The webpage that I am loading in on a server online, it has a few form elements plus a few links that when clicked I need to keep loading them inside the webview.
Now the problem is very often the page loads without the images, I can see the form elements though or only blank white page. I am testing this on wifi so internet is working fine.
Why is it not loading images and how can I make sure it does? I even tried making all images in the html page have absolute paths, but that did not help.
Later Edit: I found out what was causing this. Maybe others will run into this. I had this in the manifest file android:hardwareAccelerated="true". After removing it the content inside all the webviews is loading smoothly.
Second later edit: It is terrible, I get the initial page load now, but forms are not submitting and after some going back and forward to the webview, new images do not load anymore. Is it a memory problem? How do I make it start fresh every time?
WebView wv = (WebView) findViewById(R.id.webview);
wv.getSettings().setBuiltInZoomControls(false);
wv.getSettings().setJavaScriptEnabled(true);
wv.setWebViewClient(new WebViewClient());
wv.loadUrl(filepath);
Hi I would like to know if there is a way to make the Android Webview cache changes made to the DOM of the loaded page so that when I go back to it, the previously loaded changes remain.
An example would be I'm on page A, call javascript that adds more html content (from an ajax call or w/e), and then I go to Page B. When I hit the back button to go back to page A, page A only displays what the original page load displays.
Is there any quick way around this?
Try this
WebView view = new WebView(this);
view.getSettings().setJavaScriptEnabled(true);
view.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
view.clearCache(false);
I am working on the Google's open source Android Browser, i am working for a requirement, where i need to show some content into a new webview like a popup dialog. I shall pass some HTML data to the Webiview. I am having some JS within HTML content but the JScript is running on the main page not on the custom webview i created. Please show some way out for it.
Any JScript can be run on the webview, provided we have a script tag embedded in the HTML content rendered on custom webiew created.
Cheers
