Go back to android

I am trying to code a reverse key in android to get back to a page that is constantly updating and changing. At the moment, he just comes back with strikes seeing the change.

Here is the code

 @Override
public void onBackPressed() {
// do something on back.
super.loadUrl("file:///android_asset/www/index.html");
return;
}

I have also tried

 public boolean onKeyDown(int keyCode, KeyEvent event)  
{  
    //replaces the default 'Back' button action  
    if(keyCode==KeyEvent.KEYCODE_BACK)  
    {  
        //do whatever you want the 'Back' button to do  
        //as an example the 'Back' button is set to start a new Activity named 'NewActivity'  
        super.loadUrl("file:///android_asset/www/index.html");
    }  
    return true;  
}

The soft key is located to the right of the phone and does this with the phone connection.

Try giving some random data (or System.currentTimeMillis ()) to the end of the url :-) - after the question mark:

file:///android_asset/www/index.html?hgjhfsd

Or try:

super.clearCache();

You can achieve this using javascript. Add an event listener

Add listner

document.addEventListener("backbutton", onBackKeyDown, false);

function onBackKeyDown()
{
     window.location="index.html";
}
