Comments on: Will I Switch from iPhone to Android ? https://www.stormacq.com/two-weeks-with-android-switching-from-iphone/ Some not-so random thoughts about this small IT World Mon, 25 Jan 2016 12:47:01 +0000 hourly 1 https://wordpress.org/?v=4.9.1 By: sst https://www.stormacq.com/two-weeks-with-android-switching-from-iphone/comment-page-1/#comment-179 Wed, 30 Jun 2010 22:14:23 +0000 https://www.stormacq.com/?p=305#comment-179 @Olivier : that’s not entirely true. iPhone OS has preemptive multitasking from day #1, it’s a BSD kernel underneath. The UI did restrict application entering in background mode, which is now possible. When the user press the Home button, the application is sent in background, pretty much like what happens on Android. The big difference is that applications have to explicitly ask iOS to continue to receive notifications and be given some CPU time, otherwise it will stay frozen “to spare on resources”.
It’s a matter of three lines of code to add into your application to request permission to execute in background, not a big deal.

Hence, I do agree with Apple Marketing : iOS 4 allows to runs applications in background. Moreover, it is a fully preemptive multitasking kernel, but that’s not new. It was there since day #1

[UPDATE] This blog entry gives a very good comparison of Android vs iOS implementation of multi tasking

Big difference, although Apple and all the media wants to sell the “multitasking” tag 🙁
