Pre-Instructions for warming up Eclipse.

0. Install Eclipse and install ADT and CDT packages.

1. Import libcocos2dx project as new Android Application project. Steps:
    a. File->new->Project..->Android Project From Existing Code
    b. Click Browse button and open cocos2dx/platform/android/java directory

2. Set Path Variables for cocos2d-x root. Steps:
    a. Eclipse->Preferences->General->Workspace->Linked Resources
    b. Click the New button to add a variable called "COCOS2DX" and point it to the root cocos2d-x directory (Directory containing cocos2dx, external, scripting, tools etc.)
    c. Add "NDK_ROOT" variable for the root path to NDK from Eclipse->Preferences->General->C/C++->Build->Environment->Add

NOTE: These steps need to be done only once. After this you can import as many projects as need be, with no additional modifications

Now you can create new project using project creator, or open a sample project. 

Note: Open proj.android folder from File->New->Project..->Android Project From Existing Code
