Currently Ti.Worker only works on iOS, but this functionality would also be really really useful on Android. https://github.com/appcelerator-modules/ti.worker It has also been requested by other people https://github.com/appcelerator-modules/ti.worker/issues/12

Hello everyone. I'm glad we finally have some progress on ti.worker for Android. But there are some issues with the [PR](https://github.com/appcelerator-modules/ti.worker/pull/17), this ticket must be reopened. P.S. one more important thing to mention about Android implementation: it does not use separate js context (looks like iOS does).

And most important thing is that with <property name="run-on-main-thread" type="bool">true</property> Android implementation of ti.worker also runs code on UI thread.
