私はGCMを使いたいです。クライアント側で次のことを試しました：

アクティビティ：
package com.example.test;
import com.google.android.gcm.GCMRegistrar;
import android.os.Bundle;
import android.app.Activity;
import android.app.PendingIntent;
import android.content.Intent;
import android.util.Log;
import android.view.Menu;
import android.view.WindowManager;
import android.widget.Toast;
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
gcmRelated();
}
private void gcmRelated() {
GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
final String regId = GCMRegistrar.getRegistrationId(this);
Toast.makeText(this, regId, 10000).show();
if (regId.equals("")) {
GCMRegistrar.register(this, "609612932495");
} else {
Log.v("Register", "Already registered");
}
}
}
GCMintentService.java:
package com.example.test;
import com.google.android.gcm.GCMBaseIntentService;
import com.google.android.gcm.GCMRegistrar;
import android.content.Context;
import android.content.Intent;

import java.util.logging.Logger;
public class GCMIntentService extends GCMBaseIntentService
{
private static PowerManager.WakeLock sWakeLock;
private static final Object LOCK = GCMIntentService.class;
private static final String GCM_SENDER_ID = "609612932495";
private static final String GCM_INTENT_FILTER = "com.example.test.GCM_MESSAGE";
private static final String MESSAGE_TYPE = "Type";
private static final String MESSAGE_CONTENT = "Body";
private static Logger log = Logger.getLogger(GCMIntentService.class.getName());
public GCMIntentService()
{
super(GCM_SENDER_ID);
}

{
if (sWakeLock == null)
{
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
sWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,"sc_wakelock");
}
}
sWakeLock.acquire();
intent.setClassName(context,GCMIntentService.class.getName());
context.startService(intent);
}
@Override protected void onRegistered(Context context,String registrationId)
{
log.warning("From GCMIntentService: Device successfully registered as "+registrationId);
}
@Override protected void onUnregistered(Context context,String registrationId)
{
log.warning("From GCMIntentService: Device successfully unregistered");
}
@Override protected void onMessage(Context context,Intent messageIntent)
{
log.warning("From GCMIntentService: Game update notice received");
}
@Override protected void onDeletedMessages(Context context,int total)
{

}
@Override public void onError(Context context,String errorId)
{
log.warning("From GCMIntentService: Error "+errorId);
}
@Override protected boolean onRecoverableError(Context context,String errorId)

}
}
エラーは表示されません。GCMRegistrar.getRegistrationId(this)は常に" "(空の文字列)を返します。そのため、常に登録しようとしますが、registerId を取得できませんでした。
やるべきことはありますか？
また、サーバー側のコードを実装する際に、この登録 ID を送信し、すべての ID をデータベースに保存して送信する必要がありますか?
