How to finish an activity and return to a varied location?

Question

My application implements an action which stretch upon 3-4 activities. the entry point to this process can be from different activities in the application. (HomeActivity, various displayActivities). I want to return to the starting activity once the last activity is finished successfully.

Is there a best practice way to do it? thankyou.

You can use a global static boolean to help you with this (in the example SomeClass.IsClosingFlow), Plus, you should define each activity to "mark" if it's in the "flow" (flow=meaning it's part of the pack of activities that need to be closed). I recommend using this mark as an abstract method if you all your activities are extending some abstract-activity (i.e. isActivityInFlow()).

The following code demonstrates this, It needs to be places in onResume() of each activity in the application:

    // Check to see if we are in the process of closing activities
    if (SomeClass.IsClosingFlow){
        if (isActivityInFlow()){
            this.finish();  
        }
        else{
            // If we got here, and we're not in the flow anymore
            SomeClass.IsClosingFlow = false;
        }
    }
