我的Android项目有问题，我的项目很大，有很多方法，所以最近我试图在我的XMl文件中添加一个TextView，它可以工作，但当我试图为TextView添加ID时，我的应用程序崩溃了，所以我更改了TextView的ID，但它仍然崩溃，当我删除TextView的ID时，我应用程序工作，
然后我读了日志Cat:

所以我尝试了这个解决方案，但我的应用程序仍然崩溃，那么问题出在哪里呢，我该怎么解决这个问题？
如果您的代码中实现了Application类(如果没有创建它(。使用MultiDexApplication进行扩展。
MyApplicationClass extends MultiDexApplication
并在清单应用程序标签-中添加应用程序类的名称
android:name="your.package.name.MyApplicationClass"
