Instructions to build QGC for Android arm64

Note that generally the source of truth is CI, in this case: https://github.com/mavlink/qgroundcontrol/blob/Stable_V4.4/.github/workflows/android_release.yml

Qt

Download Qt for Open Source and install Qt 5.15.2 into ~/Qt. Make sure Android is included.

Android SDK and NDK

For these steps, choose Java 17 (or similar):

sudo apt install openjdk-17-jdk
sudo update-alternatives --config java

Install sdkmanager using Command line tools only to ~/Android.

Install Android SDK 33:

cd ~/Android
cmdline-tools/latest/bin/sdkmanager "platforms;android-33" "platform-tools" "build-tools;33.0.0"

And NDK:

cmdline-tools/latest/bin/sdkmanager "ndk;21.3.6528147"

Gstreamer

cd your-qgc-repo
wget https://gstreamer.freedesktop.org/data/pkg/android/1.18.6/gstreamer-1.0-android-universal-1.18.6.tar.xz
mkdir gstreamer-1.0-android-universal-1.18.6
tar xf gstreamer-1.0-android-universal-1.18.6.tar.xz -C gstreamer-1.0-android-universal-1.18.6

Build

For this step, switch to Java 11

sudo apt install openjdk-11-jdk
sudo update-alternatives --config java

Set Android SDK and NDK environment variables:

export ANDROID_SDK_ROOT=~/Android/
export ANDROID_NDK_ROOT=~/Android/ndk/21.3.6528147

Configure:

cd your-qgc-repo
mkdir -p build-android-arm64-qt5 && (cd build-android-arm64-qt5 && ~/Qt/5.15.2/android/bin/qmake -r ../qgroundcontrol.pro -spec android-clang CONFIG+=DailyBuild CONFIG+=installer ANDROID_ABIS="arm64-v8a")

And build:

(cd build-android-arm64-qt5 && make -j$(nproc))
