Calling a @Background/@WakeLock method in a @AfterInject method causes NullPointerException #1466

@ghost

Description

Hi there, I'm experience a bug with AndroidAnnotations 3.3.1.

I have an @efragment support fragment with an @AfterInject method where I want to perform some initialization. Calling a @Background/@WakeLock annotated method from within the @AfterInject method results in a NullPointerException.

java.lang.NullPointerException: Attempt to invoke virtual method 'android.os.PowerManager$WakeLock android.os.PowerManager.newWakeLock(int, java.lang.String)' on a null object reference : ... )

Looking at the generated code I see this:

private void init_(Bundle savedInstanceState) {
        OnViewChangedNotifier.registerOnViewChangedListener(this);
        Resources resources_ = getActivity().getResources();
        ...
        restoreSavedInstanceState_(savedInstanceState);
        init(); <- This is my @AfterInject method
        powerManager_ = ((PowerManager) getActivity().getSystemService(Context.POWER_SERVICE));
    }

The problem is that the powerManager_ is initialized after calling my @AfterInject method and thus the NullPointerException.

Shouldn't any required System Components/Services be initialized before calling any annotated method?

The fix for this would be to call any annotated methods after having first the reference to the required System Components/Services.

Putting my initialization code in a @AfterViews method doesn't result in the same exception.

Thanks in advance.
