Android: Launch mode 'single instance'

Question

I was going through the documentation for single instance and was trying out few samples. In one of my sample I have three activities: A->B->C , where B has android:launchMo

Answer 1

From the doc

1. "singleInstance" activities can only begin a task. They are always at the root of the activity stack. Moreover, the device can hold only one instance of the activity at a time — only one such task.

2. A "singleInstance" activity, on the other hand, permits no other activities to be part of its task. It's the only activity in the task. If it starts another activity, that activity is assigned to a different task
