当应用未在android中运行时，推送通知未显示

Question

我在项目中使用了推送通知，它工作正常，但是当我的应用未运行时，它不工作。 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，它将使CPU唤醒
