Android Studio编译报错“java.lang.OutOfMemoryError: GC overhead limit exceeded”

解决方法：

1.在build.gradle添加脚本指定编译堆内存

 如果在整个工程中生效，则在build.gradle中增加如下配置：

dexOptions {    incremental true    javaMaxHeapSize "4g"}

//这里的incremental true可以不添加,老版优化代码用的，新版studio已经不需要了……

 2.也可以添加gradle的配置文件指定堆内存

    在gradle.properties中修改build环境中的jvmargs参数大小：

    在项目根目录新建gradle.properties文件内容为：
