Cocoa availability on Android

Are the Cocoa libraries available on Android? If so, then how can I use them on Androi开发者_开发技巧d?

Nope. The NeXTSTEP, Cocoa and Cocoa-Touch libraries are proprietary to Apple.

GNUstep and OpenStep are projects that aim to create an open source clone of NeXTSTEP. These will not run on Android natively as far as I know, but since they are open source, you can find the project pages and mailing lists and find out if you can help out in any way. Who knows: Maybe someone else is interested in bringing them to Android?
