A new version of the example Android Ant build environment has been posted. Use this link for the Release 3 of the Android Ant Build Environment.
The new version works with slightly updated Release 10 of the Android SDK (e.g. android-sdk_r10-linux_x86.tgz). It should meet your needs for Jenkins builds and other continuous integration systems.
Let us know if you have trouble getting these build environments to work. We’d be happy to provide support.
