How do I upload my own library to Nexus one?

I'm porting my native C engine to android 2.1 using NDK r6, but I can't use the commands like: adb root or adb remout to my Nexus o开发者_StackOverflow社区ne. How should I do to upload my engine (.so file) to Nexus one?

Generally, you shouldn't add extra libraries on the phone (and rely on them). Your application should supply whatever extra libraries it needs packed within the apk and use them (and only them).
