Apktool 2.4.1 NullPointerException

Question

今天当我使用apktool反编译一些apks时，我得到了以下错误：

I: Using Apktool 2.4.1 on 025A.apk
I: Loading resource table...
I: Decoding AndroidManifest.xml with resources...
I: Loading resource table from file: C:\Users\potter\AppData\Local\apktool\framework\1.apk

但同时，我可以使用aapt2 dump badging 025A.apk来获取包名。

根据this issue的说法，通过实验，降级到2.4.0可以缓解这个问题。
