Android Question Two questions with tasklist

[jannis]

Hello,

I'm a newbie with b4a but not in Visual basic.
So for my practice i want to write a program to show some system information and a tasklist of running tasks.

The tasklist is easy to make with Activitymanager:

Dim am as ActivityManager
Dim tasks() as RunningTaskInfo = am.GetRunningTasks

For each task as RunningTaskInfo in tasks
Appname = task.GetApplicationName
Next


But the problem is that i want to get more infomation like icon, creation-date and size of the running app.

Question 1 : How to get more info about a running app ?
All Taskmanager-Apps has these Infos without root, so it must be possible


Also i want to count the starts of any apps of the system

Question 2 : is it possible to receive an event if any app is starting or must i have a look on the tasklist every 15 seconds



Thanks
Jannis

The problem is that this library (OS) doesn't expose any more information. You will need to use Reflection or JavaObject to extract more information from this object.

There is a new library that may be useful: http://www.b4x.com/android/forum/threads/beta-test-msos-getforegroundapp.34954/#content

Hello,

not really usefull. It only gives the Appname.


Can anyone answer my second question ?

I am still working on that lib. What else information do you need?

But the problem is that i want to get more infomation like icon, creation-date and size of the running app.

Get the icon from packagemanager using the packagename.
What do you mean size and creation date?

See this docs to find out what AM returns: http://developer.android.com/reference/android/app/ActivityManager.RunningTaskInfo.html

Ok, very good.

Is it possible to receive an event if any app is starting or must i have a look on the tasklist every 15 seconds ?

I think you will have to do some research on the Android developers docs and stackoverflow.
I couldnt find a way, maybe you will have to check the tasklist.
