I have a simple html5 test page which uses LocalStorage to display / save / redisplay a piece of data.
This code works perfectly in Android 2.3.x but logs an exception in 4.0.1 on line 18 of the html which is the frist localStorage.getItem() call and at this point the JS stops.
Exception: Uncaught Error: SECURITY_ERR: DOM Exception 18 at /data/data/my.app.name/app_htmlData:18
I've also tried setting the database path to getCacheDir() with the same result.
String htmlContent = "HTML content listed below";
File sharedDir = getActivity().getDir("htmlData", Context.MODE_PRIVATE);
WebView browser = (WebView)v.findViewById(R.id.wvBrowser);
browser.setWebChromeClient(new WebChromeClient(){
public void onExceededDatabaseQuota(String url, String databaseIdentifier, long currentQuota, long estimatedSize, long totalUsedQuota, WebStorage.QuotaUpdater quotaUpdater) {
quotaUpdater.updateQuota(estimatedSize * 2);
}
});
browser.setWebViewClient(new WebViewClient(){
@Override
public void onPageFinished(WebView view, String url){
view.loadUrl("javascript:doTest()");
});
browser.getSettings().setDatabaseEnabled(true);
browser.getSettings().setDatabasePath(sharedDir.getPath());
browser.getSettings().setDomStorageEnabled(true);
browser.loadDataWithBaseURL(mSharedDir.getPath(),
htmlContent,
"text/html",
"utf-8",
null);
The HTML that the page is rendering is as follows:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >

var item = read();
$('#stuff').append('<p>writing</p>');
localStorage['bar'] = new Date().toUTCString();
$('#stuff').append('<p> </p><p>reading again</p>');
read();
}
function read() {
var item = localStorage.getItem('bar');
if (item == null || (item == undefined)) {
item = '';
}
$('#stuff').append('<p> item: ' + item + '</p>');
return item;
}
</script>
</head>
