onStart method is being called in a bound service without any method call

Question

I have been going through the following google tutorial , and just had a few questions:

1. i pasted the code and ran it, and i noticed that the onStart() method gets executed. However I do not see any method call for this, how does this method get executed ?

2. can you give an practical example of how a bound service would be ideal ?

Answer 1

• That is because onStart() is called by an event, specifically, it is called when the activity becomes visible to the user.

Here's a nice explanation of the lifecycle of Android activities :
