To set up a minimal SDK installation without Android Studio, here's what I did:
mkdir ~/sdk
cd ~/sdk
wget https://dl.google.com/android/repository/tools_r25.2.5-linux.zip
unzip tools_r25.2.5-linux.zip
After successfully unpacking the zip file, I'm having a problem while updating:
tools/bin/sdkmanager --update
I get the following:
Warning: File /home/xxxx/.android/repositories.cfg could not be loaded.
done
I was hoping to get some assistance with this. Thank you.
