Retrofit: How to send a POST request with constant fields?

Question

I want to sent a simple POST request with one actual parameter:

@POST(\"/token\")
@FormUrlEncoded
void extendSession(@Field(\"refresh_token\")final String refres

It is matter of your approach. If you have the constants you can build a default Map of values required for your call. @FieldMap will be suitable for building a Map with all your required fields

private void extendSession(String token){
   Map params = buildDefaultParams();
   params.put("refreshToken", token);
   getRestAdapter().create(MyApi.class).extendsSession(params);
}
private Map buildDefaultParams(){
   Map defaults = new HashMap();
   defaults.put("client_id", CLIENT_ID);
   defaults.put("client_secret", CLIENT_SECRET);
   defaults.put("grant_type", GRANT_TYPE);
   return defaults;
}
  /**then you change your interface to this **/ 
    @POST("/token")
    @FormUrlEncoded
    void extendSession(@FieldMap() Map refreshToken);
