How can I run proj.android for android?

I have developed an application by cocos2d JS. I can run it on brower, xcode. Everything is ok. But I don’t know how to run proj.android for android

I setup environment and try run like that:
http://www.cocos2d-x.org/wiki/How_to_build_and_run_HelloWorld_on_Android(gles20_branch)

But It can’t run. Someone help me. How can I run proj.android (Published-Android)?

Just setup Eclipse environment and deploy it with Run > Android Application

Here is full tutorial: http://2sa-studio.blogspot.fr/2013/04/setup-cross-platform-project-with.html

@Tobias S: I have set up. But when Run > Android Application. Have a bug:
Errors occurred during the build.
Errors running builder ‘Integrated External Tool Builder’ on project ‘Hocvancungbe’.
The builder launch configuration could not be found.
The builder launch configuration could not be found.

I don’t know hơ to fix it. I don’t have experience in developing with android :frowning:

1.Select the right project
2.Choose "project"on the tool bar -> Properties
3.Click “Builders” in the menus of the popped up window
4.Remove the missing builders
5. Clean and build your project again
