Launch and be launched by another Android App

hello Android devs!

I’ve a Android App with an internal name “com.myUe4App”. Can another App “com.exteranlApp” simply call and open my “com.myUe4App”?

I’m reading about intents, activities, intent filters,* here… In case *is necessary to modify Ue4 to receive Launch Action… I would like to do a clear “How to” about this theme in Android.

Old thread I know but I was wondering if you found a solution to your issue. I want to do the same and I can’t find how to.
