Enabling Dependency Injection

Once you have configured the classpath correctly, the next step is start the ApplicationContext.

The following example demonstrates creating a subclass of android.app.Application for that purpose:

Example Android Application Class

import android.app.Activity;
import android.app.Application;
import android.os.Bundle;
import io.micronaut.context.ApplicationContext;
import io.micronaut.context.env.Environment;
public class BaseApplication extends Application { (1)
    private ApplicationContext ctx;
    @Override
    public void onCreate() {
        super.onCreate();
        ctx = ApplicationContext.run(MainActivity.class, Environment.ANDROID); (2)
        registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() { (3)
            @Override
            public void onActivityCreated(Activity activity, Bundle bundle) {
                ctx.inject(activity);
            }
            ... // shortened for brevity; it is not necessary to implement other methods
        });
    }
}
