Dexter VS smali

dexter (Apache 2.0);

In the past I've used 2 different methods. First was simply modifying the smali code to change values to what I want. For instance, instead of saving media to the internal SD card, I would save it to the external (for a 4WD GPS), or change the maximum amount of downloads from 10000 to 1000000.

If you access the smali github wiki, you will find this definition:

Next we need to decode/decompile the APK. So navigate to where you downloaded the APK and using Apktool decode Smart Audiobook Player using the decode argument. So our command will be apktool decode ak.alizandro.smartaudiobookplayer_2021-06-06.apk It will make a folder called ak.alizandro.smartaudiobookplayer_2021-06-06 which will contain all of the smali code (the 'assembly' language for DEX files - someone correct me with a better explanation please), the manifest.xml file of the APK, and all of the resources needed to compile our app back into a working APK file.

If interested in reversing, you’ll need tools such as (https://ibotpeaches.github.io/Apktool/ ) and dex2jar (https://github.com/pxb1988/dex2jar) and jd-GUI (http://java-decompiler.github.io/) and I also highly recommend using smali (https://github.com/JesusFreke/smali) rather than trying to analyze the machine code if jd-GUI fails to recompile something back to the pseudo-Java. There’s actually a very good LinkedIn learning video on how to use all these tools together called Learning Android Malware Analysis, just get the trial or w/e and do the course then cancel.
