              //Allow JavaScript to execute  
webView.getSettings().setJavaScriptEnabled(true);  
  
// Enable DOM cache and enable LocalStorage storage (html5 local storage method)  
webView.getSettings().setDomStorageEnabled(true);  
webView.getSettings().setDatabaseEnabled(true);  
webView.getSettings().setDatabasePath(MainActivity.this.getApplicationContext().getCacheDir().getAbsolutePath());
