I am building an android app with the facebook api and I need to import the facebook android sdk. When I want to import this file from github it throws the .."can not list the available branches..'can not open git-upload-pack'"...the detailed error was now:
https://github.com/facebook/facebook-android-sdk/: cannot open git-upload-pack
java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
Please, how can I resolve this?"
