How to get a list of the activity history stack?

Question

I'm struggling with an issue in my app. I'd like to provide a way to list the history of the previous opened activities.

I think there are two potential solutions but I'm not sure to find a stable way to achieve any of them.

• Somehow use a function from the SDK. I tried using getPackageManager() and getActivityManager() but I can't find any suitable solution
• Implement my own history but then I'll have to override startActivity and I don't really want to go down that way as an activity can be started in other multiple ways.

So is there a way to do that using a function from the SDK?

Many thanks.

EDIT:

I've got another idea, it's a bit different. Would it be possible to listen to "start/finish activity" events with some kind of receiver to a specific app (mine) and keep track of the stack history?

Using ADB commands:

adb shell dumpsys activity activities  # displays list of activities in back stack  adb shell dumpsys activity process  # displays list process in back stack  adb shell dumpsys activity intents  # displays list of pending intents in back stack  adb shell dumpsys activity broadcast  # displays list of broadcast in back stack  adb shell dumpsys activity services  # displays list of services running in back stack 

Using Activity manager:

ActivityManager m = (ActivityManager) ctx.getSystemService( ctx.ACTIVITY_SERVICE ); List<RunningTaskInfo> runningTaskInfoList =  m.getRunningTasks(10); Iterator<RunningTaskInfo> itr = runningTaskInfoList.iterator();  while(itr.hasNext()){     RunningTaskInfo runningTaskInfo = (RunningTaskInfo)itr.next();     int id = runningTaskInfo.id;     CharSequence desc= runningTaskInfo.description;     int numOfActivities = runningTaskInfo.numActivities;     String topActivity = runningTaskInfo.topActivity.getShortClassName(); }
