我为设备制造商开发了一个应用程序，它将作为系统应用程序预加载到设备中。设备制造商已预加载系统应用程序，并且在设备的系统映像中可用。现在客户端的要求是通过 Play 商店更新这个系统应用程序，就像更新 Google Play 服务一样。我在 Google Play 商店上传了更高版本的应用程序，一旦我更新了应用程序，最初应用程序崩溃并且更新不会反映在设备上，直到设备重新启动。但是，Google Maps、Google Play Services 等预加载应用程序会在从 Play 商店下载后立即更新。

我已按照 Google 支持更新系统应用程序中提到的步骤进行操作：通过 Play 商店更新系统​​应用程序（滚动到页面最后）如果有人对此有任何想法，请告诉我。

我得到的崩溃日志如下：
