问题：
由于类膨胀错误，应用程序崩溃
邵研
我正在开发一个应用程序，当我在Android6.0.1上运行时，它运行得非常好，但当我在Android4.4.2上运行时，该应用程序突然崩溃，并显示“类膨胀错误”。请帮帮我。我搜索并对我的代码做了很多修改，但没有任何帮助。一些解决方案包括在依赖项中使用multidex，以及通过stackoverflow使用少数其他解决方案。

该应用程序也在拥有android 6.0.1的LeEco mobile上崩溃，因为它在模拟器中运行，并且很少有其他设备运行相同的版本。

它的崩溃是因为添加到EditText中的可绘制的左和可绘制的开始。显然低于4.4的Android系统对该属性有问题。您可以为不同的版本使用两个xml文件，也可以使用EditText旁边的ImageView来显示您的绘图。请注意，您的代码将在任何大于4.4的设备上工作
