本文介绍了解决在使用ProGuard进行代码混淆过程中遇到的内存溢出错误的方法。通过调整JVM内存分配参数，可以有效避免因项目规模增大导致的打包失败问题。

如果项目比较大代码较多，在打包时，可能会出现

java.lang.OutOfMemoryError: Java heap space

解决方法：\sdk\tools\proguard\bin\proguard.bat

java -jar "%PROGUARD_HOME%"\lib\proguard.jar %*

添加-Xmx1024m -Xms1024m参数，调高JVM 的使用内存；即变成

java -Xmx1024m -Xms1024m -jar "%PROGUARD_HOME%"\lib\proguard.jar %*
