Introducing the MIT App Inventor, a free tool that allows anyone who wishes to build Android applications without the knowledge of any programming language.
Just for that, developed at MIT free tool called MIT App Inventor allows beginners make their first steps in developing apps for Android, experimenting around light, color and Idodotit particular user, allowing each technical knowledge bases develop applications that work for anything Android, using the browser-only (preferably chrome) without establishing any development environment on your computer.
Developing a simple application for example
We get the Screen Designer, which represents what we actually see in our app:
Drag the controls that you want to simple applications we build now: a text box, a button (both are under the tab User Interface), and Text-To-Speech (found under the Media tab):
Now, the fun part
Let's think about what we want to get out of our app on the level of text:
If we press the button, take the text inside the text box, and say it using the control Text-To-Speech.
Click the Blocks button on the right side top of the screen, next to the Designer, to replace Blocks view. Go to our button, Button1, on which we want to apply the action, and look for appropriate action (when Button1.Click do):
Now, we need to set our little function what to do. What do we want? Cause the control to the Text-To-Speech in our "talk" to the value within the text box TextBox1. We will do this:
Build the APK fileNow all that's left is to run and test it. For this purpose we have two options: either run it on our Android device, or run it on your PC Emulator. Since Emulator does not work optimally on all computers and takes a long execution time, built the APK file we will install and run on the device, and even then sign and upload the file to Google Play.
Go to menu, select Build -> App - Save to my computer process takes a few seconds (up to a minute or so). Eventually you will get the following dialog box, and you will see the APK file (attached here) drops directly to your PC. To install it, move it to your phone, make sure that the security settings of the device Unknown Sources option is selected in V, and install it using a file manager such as ES File Explorer.
That's it! Finished design, build and run your first Android app on your Android device without the knowledge of any programming language or code tinkering. This is a great tool especially for children, who want to make their first steps in programming. Good Luck!
