Contributor guide
Research direction
Start by running `ros2 run micro_ros_setup create_firmware_ws.sh android generic` followed by `ros2 run micro_ros_setup build_firmware.sh`. Inspect the undefined references from `uros/rcl/rcl/src/rcl/graph.c` and compare with the related issue 548; done means the Android generic firmware build completes without linker errors.
