android - 在牛轧糖以下的操作系统版本上获得运行时异常

Question

我的应用程序在 android 7 版本以下的手机上崩溃了。这是我申请的链接 https://play.google.com/store/apps/details?id=comdhanusharea.wixsite.benitinhere.phonebook .

我不知道为什么我会收到此崩溃报告。当我尝试在低于 Android 版本 7 的手机应用程序中安装我的应用程序时崩溃并向我展示

Unfortunately,Application is stopped

我在我的开发者帐户上收到了这份崩溃报告。

我的问题不是 Unfortunately MyApp has stopped. How can I solve this? 的重复问题我的问题与此不同，因为在编译我的项目时，我没有遇到任何类型的崩溃或错误。

我认为您的图像在 drawable-v24 或其他文件夹中，将其移动到 drawable 文件夹并再次测试。
