android index.android.bundle file

Question

I downloaded an app from Raccoon. I got these files:

com.company.name-3423.apk
config.ar-3423.apk
config.armeabi_v7a-3423.apk
config.en-3423.apk
config.iw-3423.apk
config.ru-3423.apk
config.xhdpi-3423.apk

I used apktool to get the smali code from com.company.name-3423.apk. I searched for a string that I saw in the app's UI. I found it only in the index.android.bundle file.

1. Are the apk files I downloaded part of an AAB file? If so, how do I build an AAB file from them?

2 - what is the index.android.bundle file? Is there a way to make it more readable so I can edit it and sign the app again?

Answer 1

You can try Android's bundletool. As Google explains, on building an AAB with bundletool, it may be helpful "to convert your app's compiled code and resources into app bundles".
