As we have seen previously, Libgdx can target multiple platforms such as Windows, Android or Web browser with a single source.

For each platform there is a backend which is an output stage of an app, and which can produce the result of the source code implemented in the logic part.

Libgdx currently supports four backends :

      ·         LWJGL : Runs on Windows , Linux and Mac OS X,

      ·         JOGL : also Windows , Linux and Mac OS X.

      Currently LWJGL is preferred because it is more stable, especially when it comes to                   developing a full-screen app.

      ·         Android : Allows Android development.

      ·         HTML5 : We will not be interested in developing for this platform .

      ·         iOS : Enables iOS development

Libgdx consists of 5 modules

Application: To run the app and inform about events that occur in an apps such as window resizing. It is also the module allow the ​​logging functions.

File : This is the module which allow to read, write, even copy, move and delete files

Input: This is the module that allows us to detect user input such as mouse events (Desktop) / Touch (Android) and even the accelerometer.

Audio: This is the module that allows you to play sound effects and music streaming and allows direct access to the audio device, and even create sound effects.

Graphics : Includes everything concerning the manipulation and adjustment of video and graphics mode.

Access to the Libgdx modules

Libgdx modules described above can be accessed through Gdx class , it allows easy access to the module libgdx, for example :

To access the audio module we use Gdx.audio

For the File Module is used Gdx.file

For the application module is through Gdx.app

Example of source code:

AudioDevice AudioDevice GDx.audio.newAudioDevice = ( 44100 , false) ;

Others modules?

There are other functions that are not considered as the main module and that can be useful:

      ·         math: We can make various mathematical calculations using this function.

      ·         box2d: For physical manipulation in 2D.

      ·         utils: contains helpers classes, it can also allow to read and write in JSON format.
