How to resume state of application
<p>I have one activity which starts multiple threads and one doInBackground method.
when I launch it is working fine.</p>

<p>But everytime I press the back button of the emulator and then again double click of this app it creates a new instance of the application rather than resume it where it is now.</p>

<p>I had searched out and read about onRetainNonConfigurationInstance()
but how to return instance off all the threads and doInBackground method</p>

<p>Hope anyone will understand my problem and what actually I what to do.</p>
