I tried to understand. I do not understand these aspects: Intents (I have understood a little), JavaObject and Reflection (I am totally newbie).
If someone has time for me, I am willing to pay a few email exchanges to answer my questions. I try to not be a coal nut anymore and would like to be able to use the resources provided from developer.android.
Thanks NJDude for the information. It's clear now that's the reason why I did not understood till today. So I will learn Java
But if you start learning Java, is there any reason to continue using B4A ?
Thanks Erel. I'll have to spend some more hours on JavaObject. In fact, I try not to ask the community for each "sharp" functions I would like to include in my apps
