I'll add that to my TODO list

ENV ANDROID_PREFIX /opt/android
ENV ANDROID_TOOLS commandlinetools-linux-6200805_latest.zip
ENV PATH $ANDROID_PREFIX/cmdline-tools/tools/bin:$PATH
ADD $ANDROID_TOOLS android-packages /tmp/
RUN mkdir -p $ANDROID_PREFIX/cmdline-tools \
    && unzip -d $ANDROID_PREFIX/cmdline-tools/ /tmp/$ANDROID_TOOLS \
    && echo 'y' | sdkmanager --install \
        $(cat /tmp/android-packages | grep -v -e '^#' -e '^$')

I have comments in my package file, not sure if it's supported or not.
If you don't, then you can use:
echo 'y' | sdkmanager --install /path/to/requirements/file

Similarly, i do:
RUN /tmp/install-qt.sh \
        --version $QT_VERSION \
        --directory $QT_PREFIX \
        --target $QT_TARGET \
        --toolchain $QT_TOOLCHAIN \
        $(cat /tmp/qt-packages | grep -v -e '^#' -e '^$')

Thank you so much for that script!
Mandatory nitpicks:
- use of http, not https
- no integrity checks (sha1, but that's what piss me off, see below)
- can't install cmake/ninja/conan... (you wouldn't like my patch: "The
repository structure is a mess. Try different URL variants")

I never understood why they don't have a master checksum file.
Downloading gazillion of tiny sha1 files kills the MaintenaceTool
friendliness when you're in New Zealand downloading from Japan.
Your script makes the process blazing fast (but unsafe).
Thanks for that <= odd statement
