Question

我最近在Play商店上发布了我的应用程序，引起了我的注意，该应用程序在某些设备上崩溃了。我已经对自己进行了多次测试，完全没有问题。

我没有太多阅读日志的经验，我自己也无法弄清楚问题所在。我知道该错误位于某个特定位置，但是我怎么知道导致此错误的原因呢？

以下是发生错误的类中的代码：

Answer 1

布局xml文件中有错误。请验证您的布局文件。

Answer 2

问题是，最低支持SDK为22，但是由于某种原因，我使用的可绘制图标仅受SDK 24支持。因此，SDK 22或23上的任何设备在启动时都会崩溃，因为它们无法在其中加载可绘制对象。

通过使用Android Studio中的内置矢量资源替换自定义可绘制图标来解决。
