我在我的项目中使用推送通知，它工作正常，但是当我的应用未运行时它无法正常工作。它仅在我的应用程序打开时显示。
这是我的 GCMIntentService.java ：
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) {
Toast.makeText(getApplicationContext(), "on res", 11).show();
Log.i(TAG, "Device registered: regId = " + registrationId);
displayMessage(context, "Your device "+registrationId);
ServerUtilities.register(context, "", "", registrationId);
}
/**
* Method called on device un registred
* */
@Override
protected void onUnregistered(Context context, String registrationId) {
Toast.makeText(getApplicationContext(), "on fail", 11).show();
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);
PowerManager.WakeLock sWakeLock;
//int pm = PowerManager.FromContext(context);
// sWakeLock = pm.NewWakeLock(WakeLockFlags.Partial, "GCM Broadcast Reciever Tag");
//sWakeLock.Acquire();
WakeLocker.acquire(getApplicationContext());
displayMessage(context, message);
/*if (extras.getString("message").length() != 0) {
createNotification(context, extras);
}*/
generateNotification(context, message);//registration id on gcm device registratio
// notifies user
WakeLocker.release();
}
/**
* 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, Login.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);
}
}

尝试在Android Manifest文件中授予WAKE_LOCK权限
<uses-permission android:name="android.permission.WAKE_LOCK" />
如果手机进入睡眠状态，它会让CPU唤醒
