Android application retain the state after the app is restored from minimize
<p>I have an app which starts from a splash screen and then navigates to other activities. If i press the home button in a particular activity ,the app gets minimized. Again if i click on the app icon, the app starts from the splash screen. I want to resume my app from the activity in which the home button was pressed. How to achieve this?</p>
