OS Library

[XverhelstX]

Hello everyone,

I present you thé OS Lib. aka. the Operating System Library.
This 'giant' library has around 60+ commands.
Everything is explained in the library itself.

What does it cover:

- Memory size of directories
- Tons of hardware strings (e.g model, device, host, ...)
- A unique, very easy countdown timer with 2 events (easier than timer

Dim OS As OperatingSystem
OS.Initialize("OS")
OS.CountDownTimer(1000)

Sub OS_ontick (ms as long)
       toastmessageshow(ms,false)
end sub

Sub OS_onfinish (OS As String)
    Msgbox(OS,"OS Library") 'get the secret message in here ;)
End Sub

- CPU information
- Running services, tasks, sending signals
- Rebooting (and wiping data)
- and a lot more!

Note that it is still in beta and errors may still occur. ( I haven't tested all functions yet.)
Please tell it here when, why, what, etc happened.
It is also possible that I didn't add a certain permission as I can't find them always.

I like feedback as it gives me more motivation.
(now go and make your own task killer :^))


Cheerz!

wow!

Updated to V1.1
Now you can calculate your CPU usage with calculateCPUusage

@Erel or agraham:

I seem to have a Nullpointerexception when I retrieve the currentProcesses, etc.

/**
       * Returns a list of application processes that are running on the device.
       * 
       * @return
       */
      public List<ActivityManager.RunningAppProcessInfo> getRunningAppProcesses () {
          ActivityManager am = (ActivityManager)ba.activity.getSystemService(Context.ACTIVITY_SERVICE);
          List<ActivityManager.RunningAppProcessInfo> l = am.getRunningAppProcesses();
          return l; 
      }

The error is related to here:
getRunningAppProcesses () {
ActivityManager am = (ActivityManager)ba.activity.getSystemService(Cont ext.ACTIVITY_SERVICE);

Any idea? :s

ba.activity is only available if you declare your object with @ActivityObject.
You do not need it here.
Instead use: BA.applicationContext.
This is the static context which is always available.

Thanks a lot Erel!
Here's some example code:

Msgbox(OS.AvailableExternalMemorySize,OS.AvailableInternalMemorySize)
Msgbox(OS.AvailableMemory,OS.Board)
Msgbox(OS.CPUABI,OS.Host)
Msgbox(OS.myPid,OS.myTid)
Msgbox(OS.RunningAppProcesses,"Processes")
Msgbox(OS.ReadCPUinfo,"Processes")
Msgbox(OS.RunningAppProcess,OS.Time)
Msgbox(OS.formatSize(256),"FormatSize")

Msgbox(OS.getRunningServices(10),"Running Services")
Msgbox(OS.getRunningTasks(10),"Running Tasks")
OS.killProcess(OS.myPid)

It works, however, I still have a question:

Using this:

Msgbox(OS.RunningAppProcesses,"Processes")

I receive the following information:

How can I 'interpretate' this?
Is it possible to get names, etc out of it?

Thanks

Ok, I found it.
I will add new methodes where you will be able to retrieve the pid and the process name, etc
I will update it later.

[XverhelstX]

Updated!

Now you can read different things like Processorname, etc with OS.ReadCPUinfo.

Also you can now retrieve the pid and process, service and task names!

First of all, very cool lib, thanks.

Question, regarding memory, the number obtained is what? bytes? KB? MB?, I think you should add a little bit more info about that.

I'm gonna keep testing and let you know what I find.

[XverhelstX]

It should be in bytes:
