Android NDK CI using Bitbucket Pipelines

Question

I am trying to build an NDK Android project using Bitbucket Pipelines continuous integration using ndk-build (not the newer CMAKE). But I am getting the following error when calling ./gradlew assembleDebug:

The ANDROID_NDK_HOME path seems correct as I can ls the folder and it looks correct. The permission on ndk-build also looks correctly set...

The error was that I was missing file in the apt-get install dependencies.

Here is the working bitbucket-pipelines.yml.

(I also managed to reduce the overall apt-get dependencies)
