Sample and logs from customer
From this enterprise desk case:
## Customer Description
AOT support is not working anymore on Android using the areabi-v7a ABI, while it works properly with x86. Changing the LLVM build option does not change anything. Tested as not working with the latest 4.0 Stable (attached version log) and the latest Alpha, using Visual Studio.
Running the package on an ARM device will show the following in the logs:
> 01-12 14:06:36.129: D/Mono(9987): AOT: module App64.dll.so is unusable: compiled against LLVM.
The environment file in the APK contains the following flags:
This feature is critical to make applications relevant in the marketplace, in terms of performance.
I was not able to reproduce the issue in my tests, however I was also not able to replicate all the customer's conditions precisely. I tested the issue in a LG Volt running API 19, as well as on some similar devices in Test Cloud.
The user reported the issue by testing on Android Visual studio simulator (x86) and a Galaxy Note 3 (ARMv7s running Android 5.0). I was unable to find a precise match for the Galaxy Note 3 running Android 5.0; the closest I found where Note 3 devices running Android 4.4.2 & 4.3; and Galaxy S5s running Android 5.0: https://testcloud.xamarin.com/test/app64_311aebe3-24da-4d27-91f0-726f37716e29/?step=0_0_0
