Best Android Book :
In this tutorial I thought it would be fun to make 2 apps. I make an app that grabs weather map data dynamically and displays it. I also make an app that shows how to use the camera, image picker and TinyDB with App Inventor.
I got the maps from the W Underground and weather.com. All together I show how to display images from the internet, take pictures, retrieve images from the gallery, store pictures in TinyDB, resize your app to fit any device and more. The blocks used can be found under the video below.
