apktool 反编译 Input file was not found or was not readable.问题解决方案

apktool反编译时经常会出现下面的信息
1.Input file was not found or was not readable.
2.Destination directory (C:\Users\user\a) already exists. Use -f switch if you want to overwrite it.
3.Exception in thread "main" brut.androlib.AndrolibException: Could not decode ars c fil..........
解决方案:
1和2是因为apktool升级到2.0以上时,使用方式已经替换,格式为:apktool d [-s] -f <apkPath> -o <folderPath>,参数具体的意思可以直接打apktool回车(windows)查看帮助
3是因为apktool版本过低导致,请升级到最新版本,地址:https://bitbucket.org/iBotPeaches/apktool/downloads
