Looks WAI to me, other than maybe the large number of messages in this case. An invalid debug offset is an obfuscation technique meant to exploit a bug in previous versions of baksmali, in order to prevent disassembly.

As you can see, it no longer prevents disassembly :)

Yes but application force close ???

Jun 26 '17 19:06 ghost

I don't see anything about a force close in your original bug description :). What is the exception+stack trace?

Jun 26 '17 19:06 JesusFreke

The long and enormous If you can test decompile then recompile Installed the application it will not launch

Jun 26 '17 19:06 ghost

No, I'm not installing a random untrusted apk from the web :)

Jun 26 '17 19:06 JesusFreke

Ok I'm copying the complete decompile

Jun 26 '17 19:06 ghost

I have no idea what that means. All I asked for was the exception and stack trace.

Jun 26 '17 19:06 JesusFreke

The application does not start And here is the logcat logcat.txt

Jun 26 '17 20:06 ghost

That... is not logcat. See https://developer.android.com/studio/command-line/logcat.html

obfuscators can add code to check the signature or other properties of the APK and FC if tamper is detected, and this has nothing to do with correctness of smali.
