最近使用APKtool工具反编译APK老是提示不成功，错误如下：

Exception in thread "main" brut.androlib.AndrolibException: Could not decode ars

ources.java:491)

还以为是APK做了优化升级导致呢，一直没在意。。今天又遇到这个问题，网上找了下，原来是APKTool版本不是最新的导致。。

Quick Check
Apktool 2.x (Versions after 1.5.2)
Is Java 1.7 installed?
Does executing java -version on command line / command prompt return 1.7?
If not, please install Java 7 and make it the default.
Apktool 1.x (Versions prior to 1.5.2)
Is Java 1.6 or higher installed?
Does executing java -version on command line / command prompt return 1.6 or above?
If not, please install Java 6 or Java 7.
