我有一个与此非常相似的问题。当用户收到推送通知时，我希望他们能够单击它以打开我的应用程序中的页面。这是我目前无法使用的代码。
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, ActivityPersonalRewardsGfits.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;
// Vibrate if vibrate is enabled
notification.defaults |= Notification.DEFAULT_VIBRATE;
notificationManager.notify(0, notification);
}
目前，消息已生成并调用此方法，但它不会向我的 ActivityPersonalRewardsGfits 类开放。不，这不是一个错字，程序员实际上是这样拼写礼物的。
如何让我的应用程序向该课程开放？
编辑：我的通知启动应用程序，但随后抛出此错误：
