@huydhn @kirklandsign we're trying to add android build in this unit test (also a new docker image). Do we need to add these lines

executorch/.ci/docker/ubuntu/Dockerfile

Lines 76 to 79 in f9dc6ef

	# Install lintrunner if needed
	COPY ./common/install_android.sh install_android.sh
	RUN if [ -n "${ANDROID_NDK_VERSION}" ]; then bash ./install_android.sh; fi
	RUN rm install_android.sh

to have android installed?

[kirklandsign]

to have android installed

Yes, if you need NDK build (which is true in this case right?)

[cccclai]

I think you need to add the install ndk lines here https://github.com/pytorch/executorch/blob/f9dc6ef56d305f5b9d127ce551582cea9db9cfed/.ci/docker/ubuntu/Dockerfile#L85C1-L86C1

[kirklandsign]

Also need ANDROID_NDK_VERSION=r27b here?

executorch/.ci/docker/build.sh

Lines 48 to 51 in bcea345

	executorch-ubuntu-22.04-mediatek-sdk)
	MEDIATEK_SDK=yes
	CLANG_VERSION=12
