Create a new project:
First, we would create a new project using eclipse. In different steps of project creation, we will configure the application which will affect some of our project configuration files.
Step 1: File->new->project->android application project
Here, we have namedour application, package name under which the application will run; build sdk version and minimum sdk version. Minimum sdk version is required to make your application backward compatible, i.e. to run into previous android OS based device.
