Memory leaks

[yikuo123]

        this.activityLifecycleCallbacks = new ActivityLifecycleCallbacks() {
            public void onActivityCreated(Activity activity, Bundle savedInstanceState) {
                ActivitiesLifecycleCallbacks.this.liveActivityOrNull = activity;
            }

            public void onActivityStarted(Activity activity) {
            }

            public void onActivityResumed(Activity activity) {
                ActivitiesLifecycleCallbacks.this.liveActivityOrNull = activity;
            }

            public void onActivityPaused(Activity activity) {
                ActivitiesLifecycleCallbacks.this.liveActivityOrNull = null;
            }

            public void onActivityStopped(Activity activity) {
            }

            public void onActivitySaveInstanceState(Activity activity, Bundle outState) {
            }

            public void onActivityDestroyed(Activity activity) {
            }
        };

If I finish an activity inside onCreate , the method onActivityPaused won't be called. ActivitiesLifecycleCallbacks.this.liveActivityOrNull don't free the reference to the activity and causes memory leaks!
