Get instance of current visible activity

Question

How do I get the instance of the currently visible activity in Android? I've read that I can get the ComponentName of the activity by using ActivityManager to get a list of tasks and messing with that, but that's a recipe for disaster.

Is there a way to get an instance of the topmost activity, or if the activity isn't mine and I can't access it, just null?

Please define "mine". An activity from an application you wrote, or an activity from the same application instance the accessor code is running from? — mikołak, Aug 07 '13 at 13:37

TO get instance of currently visible activity, get its context as:

Context mContext = getApplicationContext();

or

mContext = this;

now use it for this activity related tasks.

OR to get instance of another activity; keep a static ActivityClass instance somewhere else and use getter setter to get set this instance like:

public void setActivity(MyActivity activity) {
         myActivity = activity;
    }

    public MyActivity getMyActivity() {
        return myActivity;
    }
