Question

I want to track new activity start , I use this code to only get I:ActivityManager :

process = Runtime.getRuntime().exec(
                            "/system/bin/logcat ActivityManager:I");

but it gets all logcat and do not filter with such tag .

where is the problem ?

You need to tell logcat to hide the other messages.

process = Runtime.getRuntime().exec(
                        "/system/bin/logcat *:S ActivityManager:I");

*:S turns everything else silent
