stop executing a function without exiting the application
<p>Following is my code:   </p>

<pre><code>try 
{
    usrID=client.callString("VerifyUsrnameAndPswd", userName.getText().toString(), password.getText().toString());
}
catch (JSONRPCException e)
{
    Toast.makeText(this, "No internet connection", Toast.LENGTH_LONG).show();           
    Log.e("error", "client.callString exception: "+e.toString());
    e.printStackTrace();
// If this condition is true, then no need to go ahead
}
// some steps of remaining code
</code></pre>

<p>I do not want to execute the steps after the catch block, when there is no internet connection. But I don't even want to exit the application. Hence cannot use <code>final()</code>.</p>

<p>Please suggest me some function to stop the further execution without exiting the application.</p>
