我正在使用 GCM 为我的项目推送通知，但一直无法获取唤醒锁。
日志消息：

GCMIntentService---->这个类文件在里面com.thinkappz.advancedtictactoe包，但我的 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);
}
}
我也尝试过<service android:name="example.pro.GCMIntentService" />但随后它在注册时给我一个错误，说它无法实例化服务。
