Little more than a few days ago, there was word from the guys behind Paranoid Android that they were working on a new feature called Halo. Similar in form and function to the “chat heads” feature of Facebook Home, Halo was intended to bring a new level of multitasking to Paranoid Android ROMs by allowing the user to receive notifications from apps and act on them from a floating or “windowed” version of the app in question.
Despite still being at an early stage with a lot of development still to be done, the PA guys have clearly been hard at work over the past few days and decided to release some test builds featuring Halo for public consumption. This is by no means a final version and there will be bugs, some of which are mentioned in a recently posted FAQ for this new feature. There now seems to be a build available for most of the devices officially supported by PA, which now includes the Oppo Find 5. For those of you without an officially supported device, I doubt you will have to wait very long before this makes its way into many of the unofficial Paranoid Android ROMs that are out there.
All that remains now is to see how this functionality holds up in the long run, specifically in regard to playing havoc with Play Store apps, which may not take kindly to being manipulated in this way. There does not appear to be any sort of white list for completely compatible apps in place with Halo, and as to whether or not that results in the same challenges faced by the CyanogenMod after attempting to integrate Cornerstone remains to be seen. For the time being though, Halo seems to be very well received by PA fans.
These most recent builds can be downloaded from either the Google+ post linked above or from the relevant forum threads here on XDA which are linked below. Please note that there is currently no forum thread available for the Oppo Find 5.
