The Android OS is Linux, literally. So literally, it will have a Linux scheduler.
The switching generally happens based on time slices... The current scheduler used by *Linux* is the Completely Fair Scheduler.. http://en.wikipedia.org/wiki/Completely_Fair_Scheduler However, at the level of an *app* you don't see this as much. You interact with the Dalvik VM and other higher level facilities of the Android runtime system, not really the scheduler. Dalvik has a thread scheduler, or at least, what you might call a threading model. Within Dalvik, Threads are treated as actual pthreads (at least, the last time I checked). kris On Tue, Sep 25, 2012 at 5:55 PM, bob <[email protected]> wrote: > What causes the Android OS to switch to a different process? > > > Does it do a process switch after every x nanoseconds or so?
