android - VKRequest after VKSdk.authorize() throws error "invalid user id". One after another? -

i make request user profile info clicking button. debugged , when opened app , clicked on button onerror callback worked , said "invalid user id". if press button second time works fine. experiments understood app didn't complete authorization, that's why request denied. pressing button calls method code:

vksdk.authorize(vkscopes.email); vkrequest request = vkapi.users().get(vkparameters.from(vkapiconst.fields,     "user_id,first_name,last_name,sex,bdate,city,photo_200_orig")); request.secure = false; request.usesystemlanguage = true; request.executewithlistener(new vkrequest.vkrequestlistener() {      @override      public void oncomplete(vkresponse response) {          super.oncomplete(response);          //do stuff      }      @override      public void attemptfailed(vkrequest request, int attemptnumber, int totalattempts) {           super.attemptfailed(request, attemptnumber, totalattempts);           log.d("vkdemoapp", "attemptfailed " + request + " " + attemptnumber + " " + totalattempts);     }     @override     public void onerror(vkerror error) {          super.onerror(error);          log.d("vkdemoapp", "onerror: " + error);     }     @override     public void onprogress(vkrequest.vkprogresstype progresstype, long bytesloaded, long bytestotal) {          super.onprogress(progresstype, bytesloaded, bytestotal);          log.d("vkdemoapp", "onprogress " + progresstype + " " + bytesloaded + " " + bytestotal);     } }); 

i tried add if(vksdk.wakeupsession()) , passed through, cuz user not authorized yet. found in example callback ontokenexpired part of listener, i'll authorize user if needed, when added said "is never used".

how can wait until vksdk.authorize() finish working , after send request? in advance!

this line in oncreate()

vksdk.initialize(sdklistener, activity.getresources().getstring(r.string.vk_app_id)); vkuihelper.oncreate(this); 

vksdklistener

vksdklistener sdklistener = new vksdklistener() {     @override     public void onacceptusertoken(vkaccesstoken token) {     }      @override     public void onreceivenewtoken(vkaccesstoken newtoken) {         //requesting code @ top (request)         //excluding line vksdk.authorize(vkscopes.email);     }      @override     public void onrenewaccesstoken(vkaccesstoken token) {     }     @override     public void oncaptchaerror(vkerror vkerror) {     }     @override     public void ontokenexpired(vkaccesstoken vkaccesstoken) {     }     @override     public void onaccessdenied(vkerror vkerror) {     } }; 

and in onclick() there line vksdk.authorize(vkscopes.email);

note vksdklistener's callbacks not being called after initialize(), called after authorize(). don't know why, behavior of awful. great see working example gotten user's email , other things listed above.

i wrong, try change "user_id" "id". answer second question (how fetch data after authorize) simple. vksdk has listener abstract methods (and should) override.
