google cloud messaging - Android Studio doesn't recognize InstanceID class -

i want implement gcm client on android. following guide here https://developers.google.com/cloud-messaging/android/client
have downloaded configuration file , copied google-services.json file app/ directory of project.

i have added dependencies in project's build.gradle

classpath 'com.google.gms:google-services:1.3.0-beta1'

and plugin in app level build.gradle

apply plugin: 'com.google.gms.google-services'

i have included google play services sdk

compile 'com.google.android.gms:play-services:6.+'

to registration token, when use following code

instanceid instanceid = instanceid.getinstance(this);

android studio not recognize class. "cannot resolve symbol 'instaceid'". reason why happening?

update play services sdk

compile 'com.google.android.gms:play-services:7.5.0'

then clean project.

worked me. hope works too!
