我使用GCM为我的项目推送通知，但我坚持在收购之后锁定。

I am using GCM for push notifications for my project, but am stuck at acquiring wake lock.

GCMIntentService ---->此类文件里面 com.thinkappz.advancedtictactoe 包，但我的R.java文件里面例子.PRO 。我不知道为什么。

GCMIntentService----> This class file is inside com.thinkappz.advancedtictactoe package, but my R.java file is generated inside example.pro. I don't know why.

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);
    }

    /**

    @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＆LT;服务机器人：名称=example.pro.GCMIntentService/＆GT; 但后来它给我一个错误，而登记，说它无法实例化的服务。

I also tried <service android:name="example.pro.GCMIntentService" /> But then it is giving me an error while registering, saying that it can't instantiate service.

推荐答案

您正在使用的谷歌GCM客户端 com.google.android.gcm.GCMBroadcastReceiver 广播接收器图书馆。此类预期的目的服务，在您的应用程序的主包（ example.pro ），但你的意图的服务是在不同的包 - COM .thinkappz.advancedtictactoe 。这就是为什么接收机无法找到该服务。

You are using the com.google.android.gcm.GCMBroadcastReceiver broadcast receiver from the Google GCM client library. This class expects the intent service to be in the main package of your app (example.pro) but your intent service is in a different package - com.thinkappz.advancedtictactoe. That's why the receiver can't find the service.

您应该要么移动 GCMIntentService 您的应用程序，或覆盖 GCMBroadcastReceiver 的主包。

You should either move the GCMIntentService to the main package of your app, or override GCMBroadcastReceiver.
