Finding the names of the running activities

Edited to change 'running to 'running or paused and in background'

I开发者_如何学Pythons there a method which which I can log the names of the classes of the activities running or paused and in the background (i.e. not finished) in my application?

I find the shell command adb shell dumpsys meminfo com.mypackage.myapp to be most useful in managing the activity stack but it only gives me the number of activities running, not their names.

For example on startup it gives me this snippet:

** MEMINFO in pid 215 [com.mypackage.myapp] **
                    native   dalvik    other    total
            size:     4336     3203      N/A     7539
       allocated:     4326     2527      N/A     6853
            free:        9      676      N/A      685
           (Pss):     1034     1974     1994     5002

    (priv dirty):      864      684      912     2460

Now I reckon I should only have one activity occupying memory, yet it tells me there are two. I'd quite like to know what the other one is.

As soon as an activity has lost focus and another activity runs the first one is paused or stopped. The conclusion is that there is always just one activity really running and that is the visible activity on the foreground.
