Android Question How to KeepAlive without Phone library

[antonomase]

Hi,

I use the phone library just to call PhoneWakeState.KeepAlive and ReleaseKeepAlive.

Is it possible to call directly an android api to do the same thing without loading all this library ?

Thanks

The whole library will not be loaded. You should not be concerned about it. It will not have any effect on your app.

Only the PhoneWakeState class will be loaded.

OK.

For my information only : imagine I want to call the android api, how can you that ?

From my own library (I don't remember but I think that most of this code comes from Erel):

private static PowerManager.WakeLock wakeLock;

public static void SetWakeLock(BA ba, boolean BrightScreen)
{
        if ((wakeLock != null) && (wakeLock.isHeld()))
        {
            BA.Log("WakeLock already held.");
            return;
        }
        PowerManager pm = (PowerManager)ba.context.getSystemService(Context.POWER_SERVICE);
        wakeLock = pm.newWakeLock((BrightScreen ? PowerManager.SCREEN_BRIGHT_WAKE_LOCK : PowerManager.SCREEN_DIM_WAKE_LOCK)
                | PowerManager.ACQUIRE_CAUSES_WAKEUP, "B4A");
        wakeLock.acquire();
    }

    public static void ReleaseWakeLock()
    {
        if ((wakeLock == null) || (!wakeLock.isHeld()))
        {
            BA.Log("No wakelock.");
            return;
        }
        wakeLock.release();
}

Hi Informatix. I'm not 100% sure that the code you posted is exactly as it is in the library (although I'm sure Erel can confirm). The reason I say this is because I ALWAYS get a "No wakelock" message in the logs whenever I call ReleaseWakeLock - even in the cases when I know for sure that I have an active WakeLock. I don't know if this is because of some weird thing with Android where it doesn't report the current wake lock state correctly, or if the library just isn't checking it. No matter - it seems to work properly regardless.
