Workaround: remove-keepattributes localvariable*table This configuration item in the configuration file.

2. Reference library is normal, the code of the library is mixed with jar package after running error unable to execute dex:multiple Dex files define:

Unable to execute Dex:multiple Dex files define Lcom/glblong/socshare/r$anim

Workaround: The project refers to different versions of the jar package, and if the jar package versions in Libs are consistent, the problem may be caused by inconsistencies in the jar package versions introduced when using Proguradgui. That is, in the process of obfuscation, the jar packages introduced are consistent with the jar files used in the project.
