wrong in Building the container and cross-compiling
I want to build native ROS nodes using the Android NDK, and firstly I built native ROS packages, however, when I went to the third step('Building the container and cross-compiling') and run the './do_docker.sh', something wrong. It couldn't fetch sources from the link: https://dl-ssl.google.com/android/rep... and https://dl-ssl.google.com/android/rep... . Is that matter?
Please edit your question to include a link to the tutorial that you're following.
this sounds like an connection issue when the script is trying to download the android sdk. Can you run the do_docker.sh script again?
