In each RunningTaskInfo, you can find its respective top activity by: ComponentName top = task.topActivity;
But you are right, in Android system, there are multiple tasks/processes running at any given time. And telephony related tasks/services/processes will be given the highest priority. If you can find the launch date/time info. of a particular task/activity, that might help. But I guess you can only find that by "adb shell sysdump activity". You might be able to build a native .so lib to call this and dump into a txt file and JNI hook back to your Java codes to analyze the contents later, but seems it's pretty hairy :) On Fri, Aug 28, 2009 at 2:43 PM, Chris Stratton <cs07...@gmail.com> wrote: > > On Aug 28, 1:45 pm, Hong <lordh...@gmail.com> wrote: > > You can use ActivityManager to query list of running tasks > > (getRunningTasks(int)) > > Hi Hong.
