I ran into similar problem before but i don't remember the solution. It could be missing execution permisions on your gradle file

Your project is using a deprecated configuration property. Remove the ndk.dir line from android/local.properties if one is present, and remove it from YOUR_UNITY_EXPORT/local.properties. That will configure the android build to use NDK from your project modules, which is the modern way to configure it.

Edit: Sorry, I got confused myself, the rest of the comment refers to android SDK version, not NDK

In case you get NDK version errors after that: you can change the NDK version in Android Studio under File -> Project Structure -> Modules not under SDK location! Depending on your project you might need to configure it only for the unityLibrary module or the entire app. In case of React Native NDK is configured with an environment variable for the entire app and I would not recommend changing it. Usually you can change the NDK version unityLibrary requires to build in YOUR_UNITY_EXPORT/unityLibrary/build.gradle in

// ...

android {
    // ...

    defaultConfig {
        minSdkVersion 21
        // ...
    }
}

Unity will overwrite this file every time you export unless you remove the comment on line 1 of that file.
