Answer 1

see here the answer for ActivityGroup.

For child activity of a ActivityGroup, we cannot be sure that it always exist and live when we use the Context in the child activity such as PrompDialog. For example:

mPromptDialog = new LoginPromptDialog(this);//this is used as Context
//But when we use this context it may be destroyed.
//So this is the parent instance
mPromptDialog = new LoginPromptDialog(this.getParent());
