It sounds good. Since I have a Visual BASIC background, what is the best place to start learning? I assume the Android SDK can use an IDE to 'paint' forms and drag and drop controls and then I just write the code for events for each form element to do something?

Like say I want to write an app to read some integers and then report the average, mean, and median of the numbers. I'd have to have a main form, a data entry form to enter the numbers, and then a results form that displays the statistics I generated with an option to go back to the main form or the data entry form to enter new numbers? I still have to learn Activities, Fragments, Adapter and such?

I have a Samsung Galaxy S4, and a Nook HD. My son has an iPhone 5 and iPad 3. I've heard in the USA that iOS devices dominate but in the rest of the world Android devices dominate. Is that true?

Thanks for the advice, I just need to get back into the game eventually and then my programming mind will just kick right back in I hope.
