In a crash report from a user using our app I got this crash on a Galaxy Nexus running 4.2.1. I think the line numbers might be enough to know where the fix/check should be done. I have no idea how to reproduce it.

java.lang.NullPointerException

I've experienced the same issue but without a path to reproduce. The line refers to mService.isScreenOn(), it's simply delegating to the Binder interface. I'm not sure what there is to fix, or why that would be null...

Something likely crashed earlier in the boot process so the power manager
service is not registered with the service manager. All other app
processes are likely to be killed soon when the system server restarts.

I've seen this NPE a few times in a section of code that's just doing this:

PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
mScreenOn = pm != null && pm.isScreenOn();

Samsung SGH-T99 running 4.2.2:
android.os.PowerManager.isScreenOn(PowerManager.java:854)

HTC EVO running 4.1.1:
android.os.PowerManager.isScreenOn(PowerManager.java:629)
