rosdep update && rosdep install --from-paths src --ignore-src -y
colcon build
source install/local_setup.bash
ros2 run micro_ros_setup create_firmware_ws.sh android generic
ros2 run micro_ros_setup configure_firmware.sh

Additional information

The following environment variables are set:

export ANDROID_HOME='~/android_sdk/'
export ANDROID_NDK='~/android_sdk/ndk/25.2.9519653'
export ANDROID_NATIVE_API_LEVEL=android-31
export ANDROID_ABI=arm64-v8a

Comece pelo CMakeLists.txt de micro_ros_demos_rclc na linha 6 e pela configuração do microcdr registrada em firmware/mcu_ws/install; rastreie por que o build do Android rejeita a versão instalada do microcdr. Execute novamente build_firmware.sh com o ambiente Android listado e confirme que o pacote, incluindo micro_ros_demos_rclc, é compilado com sucesso.
