推荐答案

如果更新活动启动另一个安装活动，那么你可能要重写无效onActivityResult（INT申请code，INT因此code，意图意图）的更新活动，并提供以下实施。此外，当更新活动启动安装活动，就应该这样做与 startActivityForResult（意图，INT），无法与 startActivity（意向）。

If the update activity is launching another installation activity, then you may want to override void onActivityResult(int requestCode, int resultCode, Intent intent) in the update activity, providing the following implementation. Also, when the update activity launches the installation activity, it should do so with startActivityForResult(Intent, int), not with startActivity(Intent).

  @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent intent)
  {
    super.onActivityResult(requestCode, resultCode, intent);
    finish();
  }
