应用程序在android 8虚拟设备上运行良好，但在android 6.0.1硬件设备上崩溃并强制关闭。该应用程序的MinSDK版本是API21 android 5。虚拟设备应用程序功能数据库连接一切正常，但是当我尝试在硬件设备上运行应用程序时，它只显示启动画面，然后它自行关闭显示错误应用程序停止工作并在logcat中显示很多错误，我正在了解它们。我已经提供了我在应用程序内使用的所有Java代码，以便您更好地理解

真正的错误是这个：
资源 "com.example.tanishqshastri_mppolice.jansunwai：drawable/roundstatus" (7f070082( 不是可绘制对象(颜色或路径(： TypedValue{t=0x1/d=0x7f070082 a=-1 r=0x7f070082}
此可绘制对象的定义中的某些内容与Android 6不兼容，如果没有有关该可绘制资源的更多详细信息，我无法为您提供更多
帮助如果您的应用程序在 android 8 模拟器中运行良好，则不能假设它在每个以前的 android 版本上都能正常工作！如果您使用 android 6 模拟器图像，该应用程序将像真实设备一样崩溃
我将drawable-v24重命名为drawable-xxhpi，我的应用程序可以在Android 6上运行。
