我正在关注谷歌示例以在我的应用程序中使用动态交付功能。我的示例应用程序在 pie 上运行良好，但在 marshmallow 6.0.1 自定义 rom 上崩溃，因为我的选项卡在 kitkat 4.4.4 之后不支持官方更新。我在内部测试中上传了应用程序（.abb），从我的手机（os pie）和我的标签（os marshmallow）上的Play商店下载，我在两者上运行应用程序，下载动态模块，成功下载后，我启动模块，模块在 Pie 上启动，但在 Marshmallow 上崩溃，找不到资源异常。经过一些研究，stackoverflow中有人说我只是更新版本代码并重新上传应用程序，它工作正常，所以我尝试修改版本代码并测试它在棉花糖上工作正常。
有人可以帮我看看我在这里缺少什么吗？
