Checkout my first App Inventor Android App : my own light
Using the tool “App Inventor” from MIT, I create a “light” application. Download it here.
Here is a screenshot of App Inventor running my own light application.
App Inventor is a free visual tool to create simple application.
The app is very simple : it features two buttons to change the color (white or red) and a slider to change the intensity (from grey to light or from maroon to red blood).
You can download the APK here. Remember that you have to allow installing non-safe application to install apk from another location than Google Play.
