Instructions for building the Android package from source

In a Container

The easiest way to build a .apk package for Android is to use our own docker image that has all of the build components pre-assembled.

All it takes is this:

export GIT_AUTHOR_NAME=<your name>
export GIT_AUTHOR_EMAIL=<email to be used with github>

cd /some/path
git clone https://github.com/subsurface/subsurface
cd subsurface
git submodule init
git submodule update
./packaging/android/docker-build.sh

Caveat: With this build script libdivecomputer is pulled from git in the version specified in the submodule, so if you have changed libdivecomputer make sure to commit any changes and update the git submodule version before building.

This will result in Subsurface-mobile-VERSION.apk to be created in /some/path/subsurface/output/android/.

On a Linux host

alternatively you can build locally without the help of our container.

Setup your build environment on a Ubuntu 20.04 Linux box

I think these packages should be enough:

sudo apt-get update
sudo apt-get install -y \
    autoconf \
    automake \
    cmake \
    git \
    libtool-bin \
    make \
    wget \
    unzip \
    python \
    python3-pip \
    bzip2 \
    pkg-config \
    libx11-xcb1 \
    libgl1-mesa-glx \
    libglib2.0-0 \
    openjdk-8-jdk \
    curl \
    coreutils \
    p7zip-full

sudo mkdir /android
sudo chown `id -un` /android
cd /android
wget https://dl.google.com/android/repository/commandlinetools-linux-6858069_latest.zip
unzip commandlinetools-linux-*.zip

git clone https://github.com/subsurface/subsurface

# now get the SDK, NDK, Qt, everything that's needed
bash /android/subsurface/scripts/docker/android-build-container/android-build-setup.sh

Once this has completed, you should have a working build environment.

bash -x subsurface/packaging/android/qmake-build.sh

should build a working .aab as well as a .apk that can be installed on your attached device:

./platform-tools/adb  install ./subsurface-mobile-build/android-build/build/outputs/apk/debug/android-build-debug.apk

Note that since you don't have the same signing key that I have, you'll have to uninstall the 'official' Subsurface-mobile binary in order for this to work. And likewise you have to uninstall yours before you'll be able to install an official binary again.
