pubnub / android-quickstart-platform Goto Github PK

I'm sure it’s something basic, but I've cloned this repo, opened it in Android Studio, replaced the keys, and get this error message on line 22 of MainActivity.java:

/.../android-quickstart-platform/app/src/main/java/com/pubnub/android/pnquickstart/MainActivity.java:22: error: cannot find symbol
import com.pubnub.api.models.consumer.pubsub.objects.PNMembershipResult;
                                                    ^
  symbol:   class PNMembershipResult
  location: package com.pubnub.api.models.consumer.pubsub.objects

I'm getting a similar warning for all three of these import statements:

import com.pubnub.api.models.consumer.pubsub.objects.PNMembershipResult;
import com.pubnub.api.models.consumer.pubsub.objects.PNSpaceResult;
import com.pubnub.api.models.consumer.pubsub.objects.PNUserResult;

Also, on line 48 I'm receiving:

/.../android-quickstart-platform/app/src/main/java/com/pubnub/android/pnquickstart/MainActivity.java:48: error: <anonymous com.pubnub.android.pnquickstart.MainActivity$1> is not abstract and does not override abstract method file(PubNub,PNFileEventResult) in SubscribeCallback
        pubnub.addListener(new SubscribeCallback() {
                                                   ^

I'm assuming that there is something basic that I’m overlooking. Any guidance you can offer would be greatly appreciated.
