Getting android to run on SMP platform might be very different to actually run it to maximise the usage of available resources :) . Simple things like even a mutex (remember the SMP safe Mutex implementation is actually a spinlock!!!)takes on a whole different property if the code is used as is. Careful design and code changes( protection and parallelism ) would be ideally required to really benefit from the multiple cores. :)
