Build Error when using il2cpp for Android

Hi,
I have encountered a problem when building my app using IL2CPP on Android. When the message on top of the progress bar says that it's Building native binary with IL2CPP... then it crashes and prints this:

Spoiler: Error 1

I am using Unity 2019.1.3f1. Thanks.

​

 

Thanks for the response and fortunately that was the cause of the error (the NDK for some reason wasn't installed properly).

 

And so, how you did fix the problem?
Reinstall unity android pack with sdk ndk included? Has installed an android studio or ....?
Or what...? I have the same issue and tired fight with it a 3rd day

 

- OK, so, I've downloaded NDK from here https://developer.android.com/ndk/downloads - for windows x64
- Have unpacked it to MyDocuments
- In Unity 2019.1.4f1, in settings, in NDK path I uncheck "Use recommended" and type the full path to it.
- Click build
- Same error
What I am doing wrong ?

 

So, it seems the Unity android NDK from installator is corrupted.
After renaming an NDK folder from Android Player and click Build, Unity asks me to choose the path to NDK, I have chosen the new downloaded one, and it built the project. It is strange, but when I want to specify a custom folder by myself, it doesn't do anything. No popped up dialog.
