Can't use PowerManager object

in Android Processing • 2 years ago

I'm trying to turn off the whole sleep mode thing, and one of the methods I've found is ti use the PowerManager object found here. My problem is that I get an error when I try to use
PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);

Actually just declaring Powermanager pm; gives me the error "cannot find symbol"

I'm not really sure if I'm using the SDK impoperly or something, because I've got the accelerometer working.
Any sort of insight into this problem or perhaps a hint as to where I can go for more info would be appreciated.

Also, how do I point Processing.exe to my android SDK folder? I never got a dialogue so I'm a little confused. Did it do that automatically?

Okay, good news!

I've made a class that lets you start and stop a wakelock.
Here is the code:

import android.os.PowerManager;
import android.os.PowerManager.WakeLock;
import android.content.Context;

public class screenLock {
PowerManager pm;
Context context;
WakeLock wl;

public screenLock(Context parent) {
    this.context = parent;
    pm =(PowerManager) parent.getSystemService(Context.POWER_SERVICE);
    wl = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Tag");
}

public void Start() {
    wl.acquire();
}

public void Stop() {
    wl.release();
}
}

Save that as screenLock.java

Now you can make a new object and call yourobjectname.Start(); to lock the screen and yourobjectname.Stop(); to let it dim.
