Simply override your onResume() method to start the first Activity of your application.

@Override
protected void onResume() {
    super.onResume();
    // Start your first Activity as you would normally do
}

And you need not override your Home button now.

EDIT:

Since onResume() is also called the very first time when an Activity is called, therefore, you need to have a counter to know if the application is running for the first time or is it actually resuming after a pause.

int counter = 1;

@Override
protected void onResume() {
    super.onResume();
    if(counter == 1)
      counter++ ;
    else
      //Start your first Activity as you would normally do
}

  • You need to override `onResume()` for all your activities. :-) and remember to add the part of code that I have not written, starting your first `Activity` using `Intent`. – Kazekage Gaara Jun 07 '12 at 07:00

whenever you press the home button activity at that time Overwrite the onPause method that activity and when you open the app use your onResume function. Apart if you are willing to start your app from a ceratin point use Preferences variables ,in main activity check the preferences value of to start your app from a specific point.

  • override the function on Pause, write the code there whatever action you want to perform like taking a flag variable setting it's value or setting any data in preferences and now check those variable in onResume. – strike Jun 07 '12 at 10:45
