Publishing

You easily know enough to design your own app. You could even just make some modifications and add lots of new features to one of the apps from the book.

I decided not to do a step-by-step guide to publishing on Google's Play store because the steps are not complicated. They are, however, quite in-depth and a little laborious. Most of the steps involve entering personal information and images about you and your app. Such a tutorial would read something like the following:

1. Fill this text box.
2. Now, fill that text box.
3. Upload this image.
4. And so on.

Not much fun or use.

To get started, you just need to visit https://play.google.com/apps/publish and pay a modest fee (around $25) depending on your region's currency. This allows you to publish apps for life.

If you want a checklist for publishing, take a look at the following URL: https://developer.android.com/distribute/best-practices/launch/launch-checklist.html. You will find the process intuitive (if very drawn out).
