Deploying Linux to Android - therecipe/qt GitHub Wiki

Docker deployment

Install Docker: https://store.docker.com/search?offering=community&type=edition or using a package manager
If necessary run docker as root
Pull the target image

docker pull therecipe/qt:android

Deploy your application

qtdeploy -docker build android

qtdeploy -docker build android-emulator

You should find your deployed application inside the deploy subfolder.

Regular deployment

Install the [official version of Qt](/therecipe/qt/wiki/Installation-on-Linux#official-version-with-android-support)
Download the Android SDK: https://dl.google.com/android/repository/sdk-tools-linux-4333796.zip
Extract the Android SDK tools to

$HOME/android-sdk-linux/tools

If you have to, you can also define a custom location with ANDROID_SDK_DIR

Use the Android sdkmanager to download the necessary dependencies

$HOME/android-sdk-linux/tools/bin/sdkmanager "platform-tools" "build-tools;28.0.3" "platforms;android-28"

Download the Android NDK: https://dl.google.com/android/repository/android-ndk-r18b-linux-x86_64.zip
Extract the Android NDK to

$HOME

If you have to, you can also define a custom location with ANDROID_NDK_DIR

Install the Java Development Kit: https://adoptopenjdk.net/index.html?variant=openjdk8; If you have to, you can also define a custom location with JDK_DIR
If you haven't already, run the setup for android

qtsetup full android && qtsetup full android-emulator

Deploy your application

qtdeploy build android

qtdeploy build android-emulator

You should find your deployed application inside the deploy subfolder.

Signing your application

If you want to have your *.apk signed automatically, then you just need to create an jks_alias, jks_pass and an project_name.jks inside the android or android-emulator subfolder of your project's root directory.

project_name
├── android
│   ├── project_name.jks
│   ├── jks_alias
│   └── jks_pass
└── android-emulator -> ./android/

qtdeploy will then automatically build in release mode and sign your *.apk with the provided keystore using the credentials from within jks_alias and jks_pass

You can find more info about app signing and how to create a *.jks keystore here
