android - google play sevice mainactivity -


i've implemented google play services demo code found @ url:

https://github.com/kpbird/google-play-service/blob/master/src/com/kpbird/googleplayservice/mainactivity.java

and works. if function getaccountnames() called within oncreate, application momentarialy flashes before loading set content view. it's there 2 activity views being initiatied.

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     txtaccount = (textview) findviewbyid(r.id.txtaccount);     txttoken = (textview) findviewbyid(r.id.txttoken);     getaccountnames(); }

why placing getaccountnames() in oncreate create visual effect when application launches.
