我想使用GCM。我试着在客户端跟进：

的活动：

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 android.os.PowerManager;
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);
    }

    static void runIntentInService(Context context,Intent intent)
    {
        synchronized(LOCK)
        {
            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)
    {
        log.warning("From GCMIntentService: Server deleted "+Integer.toString(total)+" pending messages");
    }

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

    }

    @Override protected boolean onRecoverableError(Context context,String errorId)
    {
        log.warning("From GCMIntentService: Recoverable error "+errorId);
        return(super.onRecoverableError(context,errorId));
    }
}

它没有显示任何错误。 GCMRegistrar.getRegistrationId（this）始终返回“”（空字符串）。所以，它总是试图注册，我从来没有registerId。

还有什么要做的吗？

此外，在实现服务器端代码时，是否需要发送此寄存器ID并将所有ID保存在数据库中并发送它们？
