How does android: taskaffinity work?

Question

How does the android:taskaffinity attribute android:taskaffinity ?

According to my understanding, pressing the Home key will move the operation back to the stack, but it will not be destroyed. I'm confused.

Answer 1

You really installed a different android: taskAffinity for activity2 and for other actions. This will force the android to make another stack when (see My example).

  <activity android:name=".activity2" android:taskAffinity="com.example.act2" > </activity> <activity android:name=".activity1" android:taskAffinity="com.example.act1" > </activity> 

The following sequence should be correct. for

• Launch Activity 2.
• click home
• Launch Activity 1.
• Click Back → the desktop should be displayed.
