Retrofit 2 - URL Query Parameter

Question

I am using a query parameters to set the values needed by the Google Maps API   The issue is I do not need the  amp  sign for the first query parameter    GET   maps api geocode json        Call lt JsonObject gt  getLocationInfo  Query  address   String zipCode                                                Query  sensor   boolean sensor                                                Query  client   String client                                                Query  signature   String signature     Retrofit generates     amp address 90210 amp sensor false amp client gme-client amp signature signkey   which causes the call the fail when I need it to be  address 90210 amp sensor false amp client gme-client amp signature signkey   How do I fix this

If you specify  GET  foobar a 5    then any  Query  b   must be appended using  amp   producing something like foobar a 5 amp b 7   If you specify  GET  foobar    then the first  Query must be appended using    producing something like foobar b 7   That s how Retrofit works   When you specify  GET  foobar     Retrofit thinks you already gave some query parameter  and appends more query parameters using  amp    Remove the    and you will get the desired result
