What is the recommend way to get the main Activity from child Activity

Question

Hi,

My android application has 1 main activity. And it launches some sub-activity (which I wrote) and that also launches some sub-activity (which I wrote). I do this:

 Intent i = new Intent("my intent1");
 startActivity(i);

My question is how can each of my sub-activity and sub-sub-activity get back to the Parent activity?

Thank you.

Answer 1

You should start your sub Activities via [startActivityForResult()][1], and when you're done in your sub-activity, call finish(). This will close the sub-activity and return to the Activity that called startActivityForResult.

Answer 2

I think there is a method getParent() which returns the parent Activity of a child activity.
