dexexception: not support version

Question

I was trying to convert apk to source code. When I entered below command

./d2j-dex2jar.sh classes.dex

I got this exception:

com.googlecode.d2j.DexException: not support version.
at com.googlecode.d2j.reader.DexFileReader.<init>(DexFileReader.java:151)
at com.googlecode.d2j.reader.DexFileReader.<init>(DexFileReader.java:211)

at com.googlecode.dex2jar.tools.BaseCmd.doMain(BaseCmd.java:288)
at com.googlecode.dex2jar.tools.Dex2jarCmd.main(Dex2jarCmd.java:32)

Version of my apk is Oreo and dexcompiler is dex2jar-2.0. As much as I Know this dexcompiler supports upto N version (correct me if I am wrong). I have searched about this exception, but I didn't find any answers.

Please help me to resolve this exception

Answer 3

I me the same problem.

Use the link from @john will work under android 8.

However my device is android 10 ( this is quit common ) .

In my experience, just change the header content of dex file (039 -> 036 or other supported version) sometimes ok, sometimes failed. it depends your apk uses new Java grammar or so.
