Question

@Override
    protected void onStart() {
        super.onStart();
    }



 @Override
    protected void onRestart() {
        super.onRestart();
    }

Answer 1

Here is the activity lifecycle there is your onStart() and onRestart() methods with explanations

Answer 2

One case of onRestart() being called is when user presses home button and comes to launcher screen. In this case, activity is not destroyed and pause/stop events are fired. When user opens your app again, onRestart() for that activity is called before onStart(). You can find example here.
