我正在使用 GCM 为我的项目推送通知，但我一直在获取唤醒锁。

日志消息：

09-03 17:04:05.003: V/GCMBroadcastReceiver(5772): onReceive:com.google.android.c2dm.intent.REGISTRATION
09-03 17:04:05.003: V/GCMBroadcastReceiver(5772): GCM IntentService class: example.pro.GCMIntentService
09-03 17:04:05.049: V/GCMBaseIntentService(5772): Acquiring wakelock

下面是我的清单文件：

GCMIntentService----> 这个类文件在com.thinkappz.advancedtictactoe包里面，但是我的 R.java 文件是在里面生成的example.pro。我不知道为什么。

package com.thinkappz.advancedtictactoe;

import javax.management.Notification;

public class GCMIntentService extends GCMBaseIntentService {

    private static final String TAG = "GCMIntentService";

    public GCMIntentService() {
        super(SENDER_ID);
    }

    /**
     * Method called on device registered
     **/
    @Override
    protected void onRegistered(Context context, String registrationId) {
        Log.i(TAG, "Device registered: regId = " + registrationId);
        displayMessage(context, "Your device registred with GCM");
        Log.d("NAME", GcmMainActivity.name);
        ServerUtilities.register(context, GcmMainActivity.name,
            GcmMainActivity.email, registrationId);
    }

    /**
     * Method called on device un registred
     * */
    @Override
    protected void onUnregistered(Context context, String registrationId) {
        Log.i(TAG, "Device unregistered");
        displayMessage(context, getString(R.string.gcm_unregistered));
        ServerUtilities.unregister(context, registrationId);
    }

    /**
     * Method called on Receiving a new message
     * */
    @Override
    protected void onMessage(Context context, Intent intent) {
        Log.i(TAG, "Received message");
        String message = intent.getExtras().getString("price");
        displayMessage(context, message);
        // notifies user
        generateNotification(context, message);
    }

    /**
     * Method called on receiving a deleted message
     * */
    @Override
    protected void onDeletedMessages(Context context, int total) {
        Log.i(TAG, "Received deleted messages notification");
        String message = getString(R.string.gcm_deleted, total);
        displayMessage(context, message);
        // notifies user
        generateNotification(context, message);
    }

    /**
     * Method called on Error
     * */
    @Override
    public void onError(Context context, String errorId) {
        Log.i(TAG, "Received error: " + errorId);
        displayMessage(context, getString(R.string.gcm_error, errorId));
    }

    @Override
    protected boolean onRecoverableError(Context context, String errorId) {
        // log message
        Log.i(TAG, "Received recoverable error: " + errorId);
        displayMessage(context,
            getString(R.string.gcm_recoverable_error, errorId));
        return super.onRecoverableError(context, errorId);
    }

    /**
     * Issues a notification to inform the user that server has sent a message.
     */
    private static void generateNotification(Context context, String message) {
        int icon = R.drawable.ic_launcher;
        long when = System.currentTimeMillis();
        NotificationManager notificationManager = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification(icon, message, when);
        String title = context.getString(R.string.app_name);
        Intent notificationIntent = new Intent(context, MainActivity.class);
        // set intent so it does not start a new activity
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
            | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        PendingIntent intent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);
        notification.setLatestEventInfo(context, title, message, intent);
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        // Play default notification sound
        notification.defaults |= Notification.DEFAULT_SOUND;
        // notification.sound = Uri.parse("android.resource://" +
        // context.getPackageName() + "your_sound_file_name.mp3");
        // Vibrate if vibrate is enabled
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notificationManager.notify(0, notification);
    }
}

我也试过<service android:name="example.pro.GCMIntentService" />但是注册时给我一个错误，说它无法实例化服务。

您正在使用com.google.android.gcm.GCMBroadcastReceiver来自 Google GCM 客户端库的广播接收器。此类期望 Intent 服务位于您的应用程序的主包 ( example.pro) 中，但您的 Intent 服务位于不同的包中 - com.thinkappz.advancedtictactoe. 这就是接收方找不到服务的原因。

您应该将 移动GCMIntentService到应用程序的主包，或覆盖GCMBroadcastReceiver.
