[Android] ReactInstanceEventListener not called after initial load

[ryankask]

I'm not too familiar with Android development but I've recorded a screencast that demonstrates the issue. Basically, the below callback is only firing when the app is first started, but not when relaunched. In addition, JS animations run very slowly. I did some profiling and it seems like it's because of the app's background image not being replaced in the callback (again, I'm not too familiar with Android dev and I may be reading the profiler output incorrectly).

I've tried several RN versions and it started happening in 0.33. This is the example app:

        // After react is initialized; set our background color (override splash screen theme)
        getReactNativeHost().getReactInstanceManager().addReactInstanceEventListener(new ReactInstanceManager.ReactInstanceEventListener() {
            @Override
            public void onReactContextInitialized(ReactContext context) {
                // Hide the native splash screen
                Log.d("LPD", "called!");
                getWindow().getDecorView().setBackgroundColor(Color.WHITE);
            }
        });

@mehcode It happens when use back android button.

Fixed in v4.0.0; let me know if you still have problems. Usage changed a touch; check the example.
