dex2jar only includes class files in the converted jar

[AriaMoradi]

I have this apk: tachiyomi-zh.copymanga-v1.3.48.zip

The contents are:

$ unzip tachiyomi-zh.copymanga-v1.3.48.apk 
Archive:  tachiyomi-zh.copymanga-v1.3.48.apk
  inflating: META-INF/com/android/build/gradle/app-metadata.properties  
  inflating: classes.dex

  inflating: simp.txt                
  inflating: simplified.txt          
  inflating: AndroidManifest.xml

 extracting: res/D2.png

  inflating: META-INF/CERT.SF        
  inflating: META-INF/CERT.RSA       
  inflating: META-INF/MANIFEST.MF 

Part of the code inside the apk is using this library: https://github.com/luhuiguo/chinese-utils/blob/master/src/main/java/com/luhuiguo/chinese/Converter.java#L49 and the stacktrace is available at Suwayomi/Suwayomi-Server#512 (comment)

That library requires to load resource file /simp.txt or /simplified.txt but these are not included in the converted jar.

We are converting dex2jar via this function: https://github.com/Suwayomi/Tachidesk-Server/blob/master/server/src/main/kotlin/suwayomi/tachidesk/manga/impl/util/PackageTools.kt#L53

Is there something we can do to make dex2jar include non-class files as well?

I don't think, it's possible as of now. A short workaround would be to either use APKTool for that (if some of them are encoded, such as AndroidManifest.xml) or just unzipping them using Java APIs for that, such as ZipOutputStream
