First way to do this  <1st Mth> 

The installation of the Libgdx library is a very easy operation!

Download Library

First, go to the official site of Libgdx  

Download the latest version which is at the top:

Once the download is finished you must extract the format ". Rar" downloaded file.

We assumed that Eclipse and Android SDK are already available. If this is not the case check (link  article1 Solution pour développer des applications mobiles )

Create you first project with Libgdx.

Here are the steps to make a new project :

A- Prepare the environment for Desktop development

1 – On Eclipse, create a new Java project

Then name the project gdx-hello and click finish

Now your project is in the “package explorer “.

2 - Open it and create a file called libs in the src file of your project

Follow these steps beginning with a right click on the src file of the project

The file must be called libs as followings:

Then click finish

This folder (libs) will contain the format" .jar " library file of Libgdx.

3 - Create another file named assets

This file is to contain the resources (images , sounds, music ...) of the apps/game

Do you remember the file being downloaded, that I asked you to extract its contents. If you take a look at the file you will find:

• gdx.jar

• gdx -backend- jogl.jar

• gdx -backend- jogl - natives.jar

• gdx - natives.jar

Copy these format “.jar” files in the libs file that we created in our project gdx-hello

In this tutorial I chose the back-end JOGL that  why I use “gdx-backend-jogl.jar” and “gdx -backend- jogl - natives.jar” files   . But, if one opts for LWJGL it will be necessary to copy the format jar file of LWJGL : “gdx-backend-lwjgl.jar” and “gdx -backend-jogl-natives.jar”

Now we will add these files in the gdx-hello project

After a right click on your project make build path ​​---> Configure build path

On Library click Add JARs 

Then select the four format jar files that you will find in the libs file our project

Once the four files are selected click OK

Now, On source click Add Folder and add the assets file we created in our project

Click OK

Now your Desktop project is ready.

The only thing that remains is to write the source code.

B- Prepare the environment for Android Development

1 – First, create a new Android project :

  

Name it gdx-helloAndroid and click Next. Choose your emulator and then click Next.

Then enter the name of :

Your apps, I have named it gdx-helloAndroid

The package name, I have named it my.works.gdxhelloAndroid

And the name of the activity class I have named it main

Click finish

Now we will create a file called libs in our project.

After right click on the gdx-helloAndroid which now we can find in the “Package Explorer” make new ---> Folder

We must name it libs

Now we will put these format " jar " files that we can find in the folder you downloaded :

• gdx.jar

• gdx -backend- android.jar

• armeabi

• armeabi-v7a

3 - Now we will add the files  in our project.

After a right click on our project gdx-helloAndroid  make build path --- > configure build path

On source click ​​Add JARs , and select the two JARs files :

• gdx.jar

• gdx -backend- android.jar

Click on OK.

   

4 - Now we will import the Desktop project gdx-hello that we created

On Project click Add and select the project to import gdx-hello

It's over ! We have created a Libgdx project.

You will make the previous steps every time you when you create a new project
