Mobile IL2CPP Android

It does not like the NDK being in program files folder FYI you'll get:

clang++.exe: error: no such file or directory: 'Files'
clang++.exe: error: no such file or directory: '(x86)\Android\android-ndk-r10b/platforms/android-9/arch-arm'

Quick fix is to move the NDK to the root of your drive, I put it in a nice Android folder, as long as there are no spaces it works fine. But the bad news is currently you have to install Unity in a Path also with no spaces :S

 

Hows is the Android performance, any chance u checked?
So far in earlier builds not good as per many threads on Android section forum.
Black Screens and FPS drops?

 

So far, just getting a black screen...so not so good! Might be a 3rd party plugin or something just in the process of removing them.

 

Okay so my Mali-400 Device...BlackScreen just minimises so I can't test.

Samsung S6 edge:

Unity 5.2B -> IL2CPP build 45 fps
Unity 5.2B -> Mono build 43 fps
Unity 5.1.1p3 -> 37fps

So performance is vastly improved, but the BlackScreen is back... IL2CPP not sure how much difference it's making, but my project pushes graphics way more than scripts so, it might be I don't see to much.

BlackScreen bug reported: (Case 711221) BlackScreen then minimises on Mali-400 GPU

 

Thanks for doing the tests and posting some results + the bug reports.
Nice post

 

Hi All
Why I need r10b to compile Il2cpp? Why not latest version?

 

I would guess thats the version they was using during dev, the new version would probably work, but I would say safer to stick with r10b for the moment.

 

I could not find r10b. Where can I download it?

 

Go to Edit->Preferences->External Tools

Next to NDK is a download button

 

Preferences window changed thanks

 

Update for Unity 5.2B2...

Works again on my Mali-400...but...performance has regressed hugely.

I'm now getting very low framerates, same test as above on same device but on B2:

Unity 5.2B -> IL2CPP build 15 fps

Doh!

Strangely rebuild with Open GL 2.0 only

Unity 5.2B -> IL2CPP build 30 fps

Still much slower than B1...

 

I'll re-install 5.2 B1 and profile both on the S6, see if there is an obvious difference, I was trying to knock up a repro to file a report. I'll post some details tomorrow.

 

Okay I created a test project:

Beta 1: 33.0 FPS
Beta 2: 33.0 FPS

Set Pass 14
Draw Calls 525

Standard shader on all the objects, realtime shadows, procedural skybox...so very strange as thats very good!

I re-pushed mine...45 FPS...so not sure why the earlier test was so slow. I will have to investigate, possibly a background process killing it.

 

Device went into Power Saving mode! One to watch, it limits CPU and GPU usage.

 

One question:
similar to how IL2CPP brought ARM64 IOS support..does Android IL2CPP in 5.2 brings currently or will bring soon ARM64 support for Android and also all other 64bit support to other archs like 64 bit x86 support and MIP64 support?
thanks..

 

Well there is only 32 bit support in the build, but IL2CPP should open up 64 bit, I assume they want to get it stable before exposing that though.

 

You have results for Beta 3 Jonny Roy?

 

Beta 3 just crashes at the moment, it worked for a while with good performance. I'm submitting a bug report, I'll keep you posted, Beta 4 might fix the crash...hopefully!

 

Just FYI Beta 4 still just crashing so no more testing for the moment... bug reported friday last week: 714758

Basically it just crashes as soon as it opens, so I don't think it likes my project :S.

 

The joys of threading and shadow maps. We should be landing a fix in b5 that hopefully should address this.

 

Alex, that would be amazing, it's not holding up my project as I'm continuing in 5.1, just my testing

Thanks for coming back though.

 

Beta 5 is now out, no mention of any Mobile changes, but hope it dont crash this time, have fun Jonny

 

Hi Alex,

FYI the scene still just crashes in Unity 5.2 b5 unfortunately.

Thanks,

Jon

 

Yes, it was bug: 714758

I got confirmation that it was reproducible too, so should be all good!

 

Very unfortunate. We'll take a look.

 

Thanks Alex.

 

Hi Alex.

Latest patch fixed my crash thank you.

Jon

 

Referring back to the first post about spaces causing compile to fail, it still has problems in b6. You can now have spaces in the Unity install path but you still can't have spaces in managed DLL file names.

 

Are there any noticable performance improvements with Android IL2CPP yet?

 

I'll post some more tests soon, I'm nearly finished stage one and so it's a bit more script heavy now, but I'm also leaving on holiday for a week today, so as soon as I get back I'll do a build of each and post the results.

All I can say is on my Mali-400 device I'm now hitting 25 FPS compared to a max of around 14 FPS on 5.1, but I have been working on various elements relating to Physics which might have improved general performance.
