What application are you trying to migrate? Android is different enough, that you will probably be better off rewriting the application in the SDK framework.
The NDK wasn't designed to write whole applications, depending on how large your app is it might be better to rewrite the whole thing. But perhaps another solution is to keep what you can, and change what you need. In any case, most of the time, dropping a few thousand lines of c++ into a mobile environment just doesn't make sense (i.e., the environment is different enough that structuring your app different might really be needed, and if it's a batch processing app it might not make sense to perform some of the operations in a mobile environment...)
