Cannot import Google client after updating Android Studio -

after updating android studio 2.3 appears can not use code cloud endpoints

class endpointsasynctask extends asynctask<pair<context, string>, void, string> {     private static myapi myapiservice = null;     private context context;      @override     protected string doinbackground(pair<context, string>... params) {         if(myapiservice == null) {  // once             myapi.builder builder = new myapi.builder(androidhttp.newcompatibletransport(),                     new androidjsonfactory(), null)                 // options running against local devappserver                 // - 10.0.2.2 localhost's ip address in android emulator                 // - turn off compression when running against local devappserver                 .setrooturl("http://10.0.2.2:8080/_ah/api/")                 .setgoogleclientrequestinitializer(new googleclientrequestinitializer() {                     @override                     public void initialize(abstractgoogleclientrequest<?> abstractgoogleclientrequest) throws ioexception {                         abstractgoogleclientrequest.setdisablegzipcontent(true);                     }                 });                 // end options devappserver              myapiservice = builder.build();         }          context = params[0].first;         string name = params[0].second;          try {             return myapiservice.sayhi(name).execute().getdata();         } catch (ioexception e) {             return e.getmessage();         }     }      @override     protected void onpostexecute(string result) {         toast.maketext(context, result, toast.length_long).show();     } } 

the problem arises importing androidhttp , androidjsonfactory. used work click-alt-enter import, not now. can copy import manually

import com.google.api.client.extensions.android.http.androidhttp; import com.google.api.client.extensions.android.json.androidjsonfactory; import com.google.api.client.googleapis.services.abstractgoogleclientrequest; import com.google.api.client.googleapis.services.googleclientrequestinitializer; 

but highlights 'client', cannot resolve symbol client. gradle file has dependency compile project(path: ':backend', configuration: 'android-endpoints') , have synched.

rather trying rollback versions, there different import need use or configure differently? code on google cloud page outdated?

i added these dependencies in endpoints build.gradle file:

compile group: 'com.google.api-client', name: 'google-api-client', version: '1.22.0' compile group: 'com.google.api-client', name: 'google-api-client-android', version: '1.22.0' 

i don't know why needed, solved adding these dependencies missing packages.
