Now, I create Android Application with Titanium sdk1.5.0, and when I launched my application on Android emulator, an error message like "[ERROR] Error generating R.java from manifest" appeared.
Please tell me what should I do?
1.5.0 is still a work in progress, and so it is expected that it is unstable. The latest build of 1.4.X available here has a lot of issues from 1.4.1 fixed, and it is what most people currently use.
SDK 1.5.0 has not been officially released. Use SDK 1.4.1
