ValueError: 4 is not a valid HiddenApiClassDataItem.DomapiApiFlag

[taylor00541]

Describe what you wanted to do

Parse the dex-es in this framework.jar file, taken from a lineageos custom rom.

1. Download lineage-20.0-20240126-nightly-lynx-signed.zip from here.
2. Extract system.img from the OTA, and then get /system/framework/framework.jar
   framework.jar.zip
3. Use androguard.misc.AnalyzeDex to analyze any of the .dex inside this jar.
4. An exception is raised there, either ValueError: 4 is not a valid HiddenApiClassDataItem.DomapiApiFlag or ValueError: 6 is not a valid HiddenApiClassDataItem.DomapiApiFlag.

System Information

• Androguard Version: 4.0.2, tried also with master.
• Python Version: 3.11
• Operating System: Windows 11, tried also with Ubuntu 22
