Thanks for the reply. I understand that the $ sign is normally used to denote a nested/inner class.
In the above example (ActivityThread.java - http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=core/java/android/app/ActivityThread.java;h=d8161936a44d10ac1fac01fecb583c76190b1730;hb=76eef491e1a453174f6372d18cf500d13521fb23 ) android.app.ActivityThread$H.handleMessage Refers to the H class, which is nested in ActivityThread.java: 1621 private final class H extends Handler {....} However, as for at android.app.ActivityThread.handleDestroyActivity (ActivityThread.java:3180) at android.app.ActivityThread.access$2500(ActivityThread.java:115) at android.app.ActivityThread$H.handleMessage(ActivityThread.java: 1745) I still don't understand fully what it can mean. Looking at the source code (line number a bit off due to diff. version): (in function H.handleMessage) 1723 case DESTROY_ACTIVITY: 1724 handleDestroyActivity((IBinder)msg.obj, msg.arg1 != 0, 1725 msg.arg2, false); 1726 break; This is the section of interest. So I get ActivityThread $H.handleMessage (handleMessage function of class H nested inside ActivityThread). However, I don't get ActivityThread.access$2500 for a couple reasons: 1. Line number points to beginning of the ActivityClass 2. ActivityThread.access seems to refer to a function name, but there's no "access" function 3. access$2500 (so is access a function or class) and I have no idea what the number 2500 means 4. I would also like to know how the number 2500 is generated (is it random? depends on task #?) I tried using DDMS on a similar code, thinking that maybe (IBinder) msg.obj casting is referring to it. But when I stepped through a similar code (object casting), I didn't see "access$2500" or anything similar to it. It just jumped straight on to the function being called. I tried googling it, but to no avail...
