Question Trying to create an .apk for android, using the ECS, but the build crashes due to Burst.

Hello, I'm new to DOTS, I mainly started using it because of the determinism in its physics, which are needed for a project I'm working on.
Because I'm new I started working on a new project in Unity 2019.3.14f1 and added the Entities, Jobs, Unity Physics and Burst Packages.
And the scene in itself is just a couple of geometries with physical bodies, but when building the .apk to test on a device the process crashes and trhow these errors:


But when I dsable the Burst Compilation in the AOT settings, the errors stop and the build is done succesfully.
Still I want to know why the errors happen because Burst maybe helpfull down the road.

I found in a thread that maybe uncheckin and checking the Android NDK helps, but it doesn't do it form.
Thanks.

 

I don’t know what the error means, but for me everything works with burst on Android. I’m using the latest version of Dots packages: Burst, Entities .... I’m using the latest Unity editor version in 2019.4.x .
Try this config and see if it works.
If not, try reconstructing your entire project by creating a new one using your Assets folder, this may take a lot of time depending on your project size but at least you will be sure it’s not coming from some package cache or project wrong data files.

 

The thing is that I need to work with 2019.3.14f because of some other packages that I'm using that would have issues if I update the project version. I'll give the reconstrucion a try, thanks.

 

Here's the log, hope it helps shine a light to this.
Also I think I didn't mention it before, but because I'm not using the latest unity3D version, I'm also not using the newest packages (Physics, Entities, etc) I'm using previous ones from around May 2020
