App Inventor

App Inventor provides Android developers with a friendly environment for the creation of applications for the Android platform. It comprises a designer and a blocks editor for all the work behind the interface as well as an emulator for testing purposes. It also supports cloud-based storage of all your projects for easy access no matter where you might end up writing code and perform tests.

Use an incorporated blocks editors

There are a few steps to be taken in order to create Android apps with this utility and they include selecting the components to work with in the App Inventor Designer as well as the assembly of program blocks specifying the roles and behavior of the aforementioned components within the App Inventor Blocks Editor. This last operation is as visual as it can possible be with you putting blocks together just like in a puzzle game.

Connect your smartphone of use an incorporated emulator

Moreover, the emulator is always connected to the editor, thus adding a block and connecting it to another instantly shows the result in the emulated screen.
This can also be accomplished using a connected Android phone. The emulator alternative is constantly there though, just in case your mobile is not an option.

A last assessment

App Inventor can potentially turn you into an active, analytical contributor of the mobile community. Its toolset alongside the provided workbench make it a friendly environment to start your Android app projects in and develop them into publishable stand-alone applications.
The computer’s performance can be affected from time to time, yet the response time is good and our tests have not revealed any issues such as errors, freezes or crashes.
