NPE when injecting a static @Bean

[Tobias Preuss]

I am trying to inject a static field using the @Bean from AndroidAnnotations:

@EBean
public class LogUtil {

    @Bean(CrashReporting.class) static Reporting reporting;

    public static void log(Activity activity, String method) {
        reporting.log(activity.getClass().getName() + ":" + method);
    }

}

@EBean(scope = EBean.Scope.Singleton)
public class CrashReporting implements Reporting {

   @Override
   public void log(String text) {
       Log.d(getClass().getName(), text);
   }

}

The reporting field is null at runtime:

Caused by: java.lang.NullPointerException: 
Attempt to invoke interface method 
'void com.example.staticinjection.Reporting.log(java.lang.String)' 
on a null object reference
    at com.example.staticinjection.LogUtil.log(LogUtil.java:15)
    at com.example.staticinjection.MainActivity.onCreate(MainActivity.java:12)
    at android.app.Activity.performCreate(Activity.java:6237)
    ...

I created this demo project for you to reproduce the error.

I have not tested your sample but from what i can see in the code in this post I'd say this can't work. Injection is done when instantiating a class. That means at some point you need to either inject LogUtils or call getInstance() on the generated class as in `LogUtils_.getInstance()` (might need a context parameter).
