Issue
Probably this is not the first time you see a question like this. I'ven looking into some explanations and realized that this is related to the Gradle Plugin not downloading the default version of SDK, and since in CI you usually have a machine set up that might not have exactly the same default version installed, then it would fail.

- Android: No version of NDK matched the requested version
My question is to finally understand what is actually goin on, I am curious about WHY IT FAILS ON CI ONLY AND NOT LOCALLY IF I DO NOT EVEN HAVE ANY NDK VERSIONS INSTALLED LOCALLY
So, I ran the same command than in CI (./gradlew assembleDebug), and I end up with only a warning like this (Build was successful):
> Task :app:stripDebugDebugSymbols UP-TO-DATE
WARNING: Compatible side by side NDK version was not found for android.ndkVersion '21.3.6528147'
Compatible side by side NDK version was not found for android.ndkVersion '21.3.6528147'
However, the same command in CI end up with this result:
2020-06-25T01:45:32.2616030Z > Task :app:mergeDebugNativeLibs
2020-06-25T01:45:32.3617430Z > Task :app:stripDebugDebugSymbols FAILED

2020-06-25T01:45:32.8622201Z 148 actionable tasks: 148 executed
So, I would like to understand what would be the difference, or what would cause CI to have a different behavior than my local setup.
My local setup:
- OSX Catalina 10.15.4
- No SDK installed
- Android Studio 4.0
CI Configuration:
- GitHub Actions Android (ubuntu-18.04)
Project configuration:
- Gradle Android plugin: 4.0.0
- Gradle version (using wrapper to make sure both commands were executed with same version): 6.1.1
- Build tools: 29.0.3
Any advice is welcome, thanks in advance!
Solution
This is https://issuetracker.google.com/148189425.
The logic for selecting NDKs changed to make builds more reproducible. Changes were made to relax that when the NDK is only used for stripping dependencies, but it incorrectly only relaxes the restriction when no NDK is installed.
As to how to fix your problem, just set android.ndkVersion
to whatever you have available on CI in your build.gradle.
