Android Studio 常见错误总结

1  编译的时候出现类似 

 

this is error msg：
Cannot cast object 'com.android.build.gradle.internal.pipeline.TransformTask$2$1@35560a46' with class 'com.android.build.gradle.internal.pipeline.TransformTask$2$1' to class 'com.android.build.gradle.internal.pipeline.TransformTask'

是因为AS 的版本太高，我现在的版本是3.6.3 版本，比较高，所以会出现这个问题

解决办法换低版本的AS，那样成本比较高，可以直接修改配置

 dependencies {
        classpath 'com.android.tools.build:gradle:3.5.3'
    }

直接修改低于3.6.0 版本

 

2 在开发时候遇到这种编译异常

从log 上显示应该是资源文件报错了，但是是哪个文件报错，从log 没有办法直接判断，自己是在开发组件的时候，出现的问题

在网上查阅了下资料

我遇到的问题就是在Eclipse 项目在异动到AS 中，文件要去dom 格式，具体做法就是在右键选中，选中remove bom 问题解决！
