When I try to run the apktool to decompile my apk it gives off an error:

I followed this guide. http://www.adventuresofanentrepreneur.net/creating-a-mobile-appsgames-company/how-to-unpack-pack-an-apk-file

Am I missing some files it needs to operate?

Answer 1

I checked all the other solution but now I found i was using jdk1.6 which was preinstalled on my machine. Maybe a java update might solve this problem. The apktool documentation explicitly mentions that it needs minimum of jdk 1.7. More info here: https://code.google.com/p/android-apktool/

Answer 2

try unzip your apk file first

apk is a zipfile the message said it cannot unzip the apk first

so try your self to unzip the apk file to find whether it is a real apk

Answer 3

This error means Apktool cannot open the Zipfile to read the files it wants ( classes.dex in this case). Try using a regular Zip program (Like 7zip or Winrar ) and try and unzip the apk. If this works, then apktool is at fault and you should report a bug. However, I believe it will fail, in which case you need to figure out why that is. It could be any of the following reasons:

1. Apk utilizes the "general access bit" hack, which no longer runs on Android, thus apktool removed support for it.
2. Apk has a password on it.
3. Apk was improperly downloaded, thus not complete
