Question

Is there a way to set which activity is to be started anytime the application is opened? Obviously I have the Intent Filters android.intent.action.MAIN and android.intent.category.LAUNCHER, but I want it to reset to this activity even if the App wasn’t completely killed (if it wasn’t, now it just goes back to the last activity that was open)

Answer 1

So you want to go straight to your initial activity every time you start the app from the launcher? Set android:clearTaskOnLaunch to true in your Activity tags in the manifest.

from the docs

Whether or not all activities will be removed from the task, except for the root activity,     
whenever it is re-launched from the home screen — "true" if the task is always stripped 
down to its root activity, and "false" if not. The default value is "false". This 
attribute is meaningful only for activities that start a new task (the root activity);
it's ignored for all other activities in the task.
