Actually you need to provide the complete role name like below;
my role:
role c5XXXXtrial.hanainstance.ETATracker.ETATrackerBL.roles::newrole {
}
sql call:
call "HCP"."HCP_GRANT_ACTIVATED_ROLE"('c5XXXXtrial.hanainstance.ETATracker.ETATrackerBL.roles::newrole')
It worked for me and this should also work for you 
, make sure all the files are saved and activated.
