To be honest I don't see a security issue in the part of "get
information about", only in the "influence".
That's because it's posible to get the current activity's package with
ActivityManager.getCurrentTasks from a bacgkround service without any
problem right now. I just wanted to avoid polling periodically for the
current task - having a simple callback like "activity got started, lost
focus" would help me in this manner ... That ActivityMonitor is so
complicated and has so many envents that I hoped it will have something :)
I need this in a custom device which will have some leds/extended
keyboard for our custom aplications.
Those leds should have different status depending from which activity is
running on it (browser, email, etc.).
So I don't want to hack anything - it's only about the backlight of some
buttons :)

As a general rule it is not possible to get information about, or
influence other applications on an un-rooted Android. The exception is
where the application is designed for external interaction and has
prepared public intents or broadcasts to allow this.

No, sorry.
