(Android) 새롭게 바뀐 구글 GCM Client 어떻게 바뀌었나?

안녕하세요.

시원한물냉입니다.

저번 GCM 1탄(?) 초기버전 포스팅에서는 불펌(?) 논란이 있었죠.. 한자 한자 열심히 적었는데 말이죠.

오늘은 언제부턴가(?) 바뀐 GCM Client 정보를 가져왔습니다.

몇버전부터 바뀐건지 아시는분은 댓글로좀 알려주세요 !  ^^

우선 참고할 사이트는

http://developer.android.com 입니다. 안드로이드 API사이트이구요.

여기에 Google Could Message  GCM 찾아보시면 아주 잘 설명되어있습니다.

우선 이전과 달라진점중에 제일 큰건 regID 즉 푸시키를 받아오는 소스가 엄~~청 길어졌다는겁니다.

아마도 이전에는 gcm.jar 에 들어있던게 모두 밖으로 풀어헤져진게 아닌가 싶은데요.

아래 모든 소스의 패키지명은 com.google.gcm 으로 정하였습니다.

Manifest 로 가서 permission 부터 설정해줍니다.

<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.GET_ACCOUNTS" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <uses-permission android:name="android.permission.VIBRATE" />   <permission     android:name="com.google.gcm.permission.C2D_MESSAGE"     android:protectionLevel="signature" />   <uses-permission android:name="com.google.gcm.permission.C2D_MESSAGE" />

다음으로는 

<receiver     android:name=".receiver.GcmBroadcastReceiver"     android:permission="com.google.android.c2dm.permission.SEND" >     <intent-filter>         <action android:name="com.google.android.c2dm.intent.RECEIVE" />         <category android:name="com.google.gcm" />     </intent-filter> </receiver>   <service android:name=".GcmIntentService" />   <meta-data     android:name="com.google.android.gms.version"     android:value="@integer/google_play_services_version" />

meta-data 라는 새로운게 생겼는데요. 이거 안넣으면 어플 실행이 안됩니다. 꼭 넣어주세요.

MainAcitvity입니다. 이전버전과는 다르게 또 이건 Activity로 실행됩니다.

Loading 정도에서 startActivity 한번 하면 될듯합니다.

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()) + "|");       }       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);    } }

그리고 GCMIntentService -> GcmIntentService

소대문자만 바뀐거같다.. 내용은 다바뀌었고

이상 여기까지입니다. 이전에는 소스 10줄 내외로 끝나던 regID 받아오던게 이렇게 소스가 길어졌네요... 모바일은 정말 최신버전이 나올때마다 개발자는 API바뀔까바 두근두근하는거같네요 휴 오늘도 그럼 즐코딩하세요!
