Rebuild error

Prerequisites

• Installed the tool in a way described in the readme and ran python3 -m obfuscapk.cli --help without any errors
• Ran the tool using only Rebuild, NewSignature and NewAlignment obfuscators to verify that the app is not using anti-repackaging techniques
• Ran the tool using --ignore-libs to exclude third-party libraries from the obfuscation
• Checked that the issue isn’t already filed: https://github.com/issues?utf8=✓&q=is%3Aissue+repo%3AClaudiuGeorgiu/Obfuscapk

Description

Steps to Reproduce

Expected behavior:

As expected, “ClassRename” option only rename class name.

Actual behavior:

But somehow, It has added more methods to dex file.

Hi guys, I’m having the same problem.

The tool is excellent, most commands work correctly. The apk is crashing when using “ClassRename”. Maybe the mapping of the renamed classes is not being done correctly. Has anyone made the apk work with this command?
