Hi All,
Device Used: Samsung Rugby Smart i847
OS         : Android OS, v2.3.6 (Gingerbread.UCLA4)

My VOIP Android Application has the C/Native Library which does all business 
logic of login/Logout etc.
 
Issue with this is when the device screen is locked the application(c Code) is 
not able to receive any packets from the server. I verified this with 
Wireshark. It looks like the CPU is not running.

I was able to solve the issue doing below on my application INIT.

    WakeLock mWakeLock =  null;
    PowerManager pm = (PowerManager) 
cxt.getSystemService(Context.POWER_SERVICE);
    if(mPartialWakeLock == null){
        // lock used to keep the processor awake.
        mPartialWakeLock = pm.newWakeLock(
            PowerManager.PARTIAL_WAKE_LOCK
                | PowerManager.ON_AFTER_RELEASE, TAG);
        mPartialWakeLock.acquire;
    }
            
            

But doing above will drain my battery.

Why the requests are not reaching my application? How can I make device CPU up 
all time when Screen is LOCKED and receive requests from the Server?

Note: The the application works on Galaxy s2.(Is it because its Dual Core 
Processor and CPU is up on Screen LOCK?).Is this a Device Issue???

Thanks
NITZ
