Question

I have multiple activities in my application .
The flow for activities is

A->B->C…

A->D->E…

A->F->G..

….

And each has a back button to go back to previous activity and home to go back to A.

My question is when i launch each of these as singletask, i can visible feel fast switching between activities when i click back or home. I dont see any issues if i keep them as singletask.

BUt are there any issues that i am verlooking if i keep the activities as singletask in my application. Thanks a lot for your time and help

Yes there are issues in changing the behaviour mode of activity from mainfest.xml, When you will press the home button for android home screen and get back to the application the previous activity will be gone and will finish the application, then better is to use intent instead using single task mode, you can use flags with intent to cleat the activity stacks..and by launching the mode in single task you are changing the systems settings, why dont you keep the launch mode and give it to system for handling the activities..!

Intent intent = new Intent(getApplicationContext(),A.class);
            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(intent);
            finish();
