我正在使用此代码显示本地通知，当通知出现时，单击通知时想要启动 ListActivity，但在 Google Nexus 设备上 ListActiviy 在单击通知时不会启动，而是在此代码运行良好的其他设备。

    Intent notificationIntent = new Intent(context,
            ListActivity.class);
    notificationIntent.putExtra("clicked", "Notification Clicked");
    notificationIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |   Intent.FLAG_ACTIVITY_SINGLE_TOP);   // To open only one activity on launch.
    PendingIntent pIntent = PendingIntent.getActivity(context, reqCode,
            notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationManager nM = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    NotificationCompat.Builder notify = new NotificationCompat.Builder(
            context);

    notify.setContentIntent(pIntent);
    notify.setSmallIcon(R.drawable.app_icon);
    notify.setContentTitle("Hello World");
    notify.setContentText("");
    notify.setAutoCancel(true);
    Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    notify.setSound(alarmSound);
    notify.setLights(Color.BLUE, 500, 1000);
    nM.notify(reqCode, notify.build());

在activity未启动时添加logcat:

最佳答案

这是 kitkat 4.4 报告的问题，单击通知时未打开 Activity ，这是一个问题 url

http://code.google.com/p/android/issues/detail?id=61850

建议的解决方法是取消现有的 PendingIntent，或使用 PendingIntent.FLAG_CANCEL_CURRENT

或

试试下面

在AndroidManifyt.xml中的Activity中添加一个标志

android:exported="true"
