You have come to the right place.
The traditional method of learning to program Android is to go the java route, very complex, will take up your life for the next ten years.
Here we have one man called Erel and I'm sure I will not be the only person to call him a genius!
Erel has developed a beautiful system where you program Android using the programming language of BASIC.
Oh I don't want to program in BASIC you might say to yourself but hold on just a second there and consider this:
Do you want to make amazing apps for Android in this, your lifetime?
Would you consider also programming for the iPhone? Because if you program carefully you can use much of the same code that you used for Android!
This amazing development environment is now FREE! We all used to pay 200 dollars every other year, happily I might add but now Erel is giving it away for free! Amazing!
"The proof is in the pudding" an English saying meaning that if you create an amazing app in Android, your potential buyers won't care 'how' you did it.
This forum is full of lovely people, all programming in B4x and all willing to help you on your journey.
Have fun!
