android - 为什么我的 Intent 在我的应用程序的设置中打开应用程序信息，而不是我传递给它的 Activity 类？

Question

我有一个 Activity ，它通过通知启动前台服务。如果相关，服务也可以设置为开机启动，即。我希望它也能够在没有 Activity 的情况下启动。

我希望它是这样的，如果我点击通知，然后我会转到我的 Activity ，在那里我可以停止服务、更改设置等。

我将带有 Activity 类的 Intent 提供给 PendingIntent 以用于前台服务的通知。

如果我点击通知，它会在我的应用程序的系统设置中打开应用程序信息(您可以在其中强制停止、卸载等)，而不是 Activity 本身。我怎样才能让它做后者？

这是在服务启动时创建通知的代码:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Context con = getApplicationContext();
    String chanID = "com.blah.MyApp";
    NotificationChannel chan = new NotificationChannel(chanID, getString(R.string.app_name), NotificationManager.IMPORTANCE_NONE);
    NotificationManager manager = (NotificationManager) con.getSystemService(Context.NOTIFICATION_SERVICE);
    manager.createNotificationChannel(chan);

    PendingIntent penitent = PendingIntent.getActivity(con, 1, new Intent(getBaseContext(), MyApp.class), 0);
    Notification notif = new NotificationCompat.Builder(con, chanID).setContentIntent(penitent).build();

    startForeground(1, notif);
...

我也尝试过创建 Intent

 Intent.makeMainActivity(new ComponentName("com.blah", "MyApp"));

同样的结果。我想知道问题是否与上下文有关？

编辑:我也无法更改通知上的文本。

我还应该提到这是 LineageOS Android 风格。谢谢。

Answer 1

如果我设置了一个我还没有制作的图标，这是可行的，因为艺术缺陷。 Unlike this question在这种情况下不需要先设置图标。

就好像它忽略了传递给 startForeground 方法的通知并提供默认通知，除非它包含图标。

一旦我通过 setSmallIcon(R.drawable...) 添加了所有按预期工作。
