kinda curious about the crystal ball for the android market that you seem to have. first thing is the treble project is only for android 8 and above. next thing is android 8 requires a specific set of hardware in order for a device to be able to run it. there is a whole set, perhaps the majority of the current devices, that are not open to get the oreo update and so treble project don't mean jack for those devices.. does your crystal ball show that rock64 can run android 8? read this and then check back in,

"Specific set of hardware" "majority of current devices" "random document that is only sort of related" 

So negative. May I suggest some vitamin D? Also can the rock64 run android 8 in the future? Sure, this comes from someone who has ported android to a myriad of various devices that weren't "supported". Will it be alot of work? Yes. 

I mean even android 7.1.2 isn't fully running on the rock64 today. That doesn't mean that with effort from the community we can't get there.

not negative, just realistic. it's obvious you did not read the linked document so your comprehension is affected no doubt. but hey, let's just wait and see. oh, one last thing, the main thrust of the post was the treble project, well the treble project is based on the full build so probably little chance it relates to the rock64.

see, here is just a sample of the requirements, maybe someone can read it to you, i fully expect you to mention the rock64 is not a handheld device, perhaps, but the majority of android devices are handheld thus the requirement for the full build. if you take the not handheld track just skip down to the tv box set of requirements. now, show everyone how smart you are by quoting the whole post, Smile

Damn son, I'm thinking something stronger maybe in order for that mood disorder. All I was trying to say was pointing out some doc and saying its impossible because of a capital "must" is silly and really not needed. 

It is truly magical what a line of code here and there can accomplish. You must believe that, else why would you be here hacking on this relatively new SBC.

That's all I will feed to the troll. Seriously though relax. You'll live longer.  Cool
