Android Studio에서는 이렇게 해야한다.
Google Play Service 연결하기
- 이클립스 – Windows – Android SDK Manager 를 연다.
- 목록의 제일 아래쪽에 Goole Play Services 선택한다.
- 오른쪽 아래의 Install 버튼을 누른다.
- 설치가 끝나면 이클립스의 프로젝트 목록에서 오른쪽 클릭해서 import 메뉴를 선택하고,{sdk}/extras/google/google_play_services/ 를 선택한다.
- 작성할 프로젝트의 오른쪽 클릭 메뉴 – properties – Android – Library – Add… 버튼을 누른다.
- google-play-services_lib 를 선택한다.
Manifest 편집
kr.mint.testgcm 이라고 적힌 부분은 실제 패키지 경로로 바꿔야 함.

Registration ID 복사해두기
정상적으로 등록이 됐다면 logcat 에 RegID가 나올텐데, 이걸 복사해뒀다가 송신 서버 만들 때 쓰자.
Error – SERVICE_NOT_AVAILABLE
도움받은 곳 : http://aroundck.tistory.com/2353
java.io.IOException: SERVICE_NOT_AVAILABLE at com.google.android.gms.gcm.GoogleCloudMessaging.register(Unknown Source) at com.mintshop.candibox.activities.MainActivity$3.doInBackground(MainActivity.java:151) at com.mintshop.candibox.activities.MainActivity$3.doInBackground(MainActivity.java:1) at android.os.AsyncTask$2.call(AsyncTask.java:288) at java.util.concurrent.FutureTask.run(FutureTask.java:237) at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:231) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1112) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:587)
이런 에러가 나오면 다른 방법으로 regId를 받아와야한다.
<receiver
android:name=".receiver.GcmBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" /> <!-- add this line -->
<category android:name="kr.susemi99.testgcm" />
</intent-filter>
</receiver>
menifest.xml 에 저 부분을 추가하면 broadcast receiver에서 regId를 받아올 수 있다.
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
Log.i("GcmBroadcastReceiver.java | onReceive", "|" + "=================" + "|");
Bundle bundle = intent.getExtras();
for (String key : bundle.keySet())
{
Object value = bundle.get(key);
Log.i("GcmBroadcastReceiver.java | onReceive", "|" + String.format("%s : %s (%s)", key, value.toString(), value.getClass().getName()) + "|");
if (key.equalsIgnoreCase("registration_id"))
{
String regId = bundle.getString(key);
PreferenceUtil.instance(context).putRedId(regId);
}
}
Log.i("GcmBroadcastReceiver.java | onReceive", "|" + "=================" + "|");
// Explicitly specify that GcmIntentService will handle the intent.
ComponentName comp = new ComponentName(context.getPackageName(), GcmIntentService.class.getName());
// Start the service, keeping the device awake while it is launching.
startWakefulService(context, intent.setComponent(comp));
setResultCode(Activity.RESULT_OK);
}
}
preference에 저장하는 부분을 여기서 하면 된다.
