LibGdx a cross-platform game development framework and a best way for beginners who turned into game development. Using LibGdx one can build 2D or 3D games with little efforts only you need to be familiar with the basic programming language. There is a core project that needs to create on java and some little coding needs to make it executable in different platforms like desktop, Android,IOS Html5 etc. We will focus on to develop android games. I am going to start with the very basics step that needs to be setup before the coding part. And then we build some Demo Projects and try to get understand that how the whole code is working. To work on LibGdx you need to install Java JDK, Android SDK and Ecllipse. There is a TroubleFire section in the blog where you will find solutions of the troubles that might come during your work.
