Try by putting this in OnCreate():

//context is Activity context
context.deleteDatabase("webview.db");
context.deleteDatabase("webviewCache.db");

Also try this:

CookieSyncManager.createInstance(this);         
CookieManager cookieManager = CookieManager.getInstance();        
cookieManager.removeAllCookie();

Try following methods of Webview,

mWebView.clearFormData();
mWebView.clearCache(true);

And to remove the EditText's border you need to declare following property in your .xml file.

android:background="@null"

i think that is default, if you test in different device the border color may change...you really wants to remove it? – Vamshi Feb 27 '14 at 08:53

// turn caching off webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);

and use LOAD_CACHE_NORMAL for default behavior.
