How do I clear previous WebView's content before loading the next WebView?

Question

My scenario is initially I am loading a WebView and later on I am loading the same WebView with a different URL.

My problem is whenever I am loading the next URL I c

Answer 1

use mweb.clearView(); before loading the new URL.

Edit:

clearView() was deprecated in API level 18. Use WebView.loadUrl("about:blank") to reliably reset the view state and release page resources (including any running JavaScript).

to solve the issue raised by @Liang:

To have a consistent back navigation, you can override "onPageFinished", and inside it check whether the url contains "about:blank" or not. if yes, use "webview.goBack()"

Answer 2

It seems to set the layer type of webview as "software" can resolve the problem. Perhaps the previous contents are caused by drawing cache.

Answer 3

Create a string with the HTML for a blank page and load that into the webview. Or hide it until it is loaded.

Answer 4

use following statement before loadData [Kuldip Bairagi]

view.loadUrl("javascript:document.open();document.close();");

Answer 5

I guess you can use Webview.clearHistory(). But remember so impotent to call this after WebView is loaded. For example the code:

webView.loadData(someUrl);
webView.clearHistory();

won't work because webView is not loaded. We have to clear it like:

webView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                clearHistory();
            }
}

Answer 6

I usually hide the webview before loading the new url, and then show it again when the loading progress has advanced a bit.

// url loading
mWebView.setVisibility(View.INVISIBLE);
mWebView.loadUrl(newUrl);

// show webview again
mWebView.setWebChromeClient(new WebChromeClient() {
    @Override
    public void onProgressChanged(WebView view, int progress) {
        if (progress >= 10) {
            mWebView.setVisibility(View.VISIBLE);
        }
    }
}
