Ubuntu下gradle运行卡住，出现Exception in thread "png-cruncher_xxx"错误的解决办法

ubuntu下用GRADLE 编译android应用，一直卡住，看了一下错误日志：

Thread(png-cruncher_14) has a null payload

原因是，我是64位的系统，系统缺少32位的相关依赖库。

打开终端依次运行以下命令，重新编译就可以了

1. sudodpkg--add-architecturei386
2. sudoapt-getupdate
3. sudoapt-getinstalllibncurses5:i386libstdc++6:i386zlib1g:i386
