The past few weeks I have been fighting apktool, smali, backsmali tasks going between KitKat and Jellybean. The newer SDK 19 compiled apps require newer versions of apktool. The newer versions of apktool require Java 7. Using Java 7 breaks the older apk manager tools. See where I am going here?
I have taken the existing apk-multi-tool scripts, tools, etc.. and updated it to work properly with Java 7. Now you will no longer have to jump back and forth between Java 7 and Java 6 and getting errors installing frameworks. You will need Java 7 to use this tool.
