如何修复Android兼容性警告 [英] How to fix Android compatibility warnings

问题描述

我有一个针对Android 9的应用程序，我在Google Play的预发布报告中注意到一个名为"Android兼容性"的新部分.此新部分列出了与使用不受支持的API有关的警告或错误.以下是问题之一，并被列为灰名单API.有人可以在这种情况下解释不支持的API吗?用法似乎来自Android支持库，而不是我的代码.

I have an app that is targeting Android 9 and I noticed in the Google Play prelaunch report a new section called Android compatibility. This new section lists warnings or errors related to the usage of unsupported APIs. The following is one of the problems and is listed as a greylisted API. Can someone explain which is the unsupported API in this case? The usage seems to be coming from the Android support library and not my code.

推荐答案

我想我们现在无能为力，只是等他们解决了AndroidX中的这些问题(因为支持库将不再更新).br>如此处所述，方法使用反射，所以为什么要发出警告.

I suppose there nothing we can do right now, just to wait that they fixed these issues in AndroidX (as Support Library won't be updated anymore).
As mentioned here the methods use reflection, so why the warning.
