I am working on a React-Native project using Unity (asmadsen/react-native-unity-view). The code is working properly on both Android and iOS and build is also being generated for both the platforms respectively. But now I am trying to make the build through Appcenter for Android doing all the necessary setup process but it's failing all the time. But when I am doing the same for a demo React-Native project, the build is successful on the Appcenter.

The error logs as found on the Appcenter is :

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/runner/work/1/s/android/UnityExport/unityLibrary/build.gradle' line: 66

* What went wrong:
Execution failed for task ':UnityExport:BuildIl2CppTask'.
> Location specified by ndk.dir (/Applications/Unity/Hub/Editor/2020.3.16f1/PlaybackEngines/AndroidPlayer/NDK) did not contain a valid NDK and couldn't be used

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 3m 56s

Can anyone has any idea and help me over the same. Thanks in advance.

It's seem that you haven't valid NDK on your computer, for unity 2018 you must install android-ndk-r16b and for unity 2020 you must install android-ndk-r19.

depend on your OS and unity version download and install valid NDK from NDK.

  • only extract it and in unity **Edit> Preferences... > External Tools ** change the NDK path to extracted folder – eager Oct 12 '21 at 21:33
