JADX is a powerful used for decompiling Android APK files, transforming DEX bytecode into human-readable Java source code. By providing a user-friendly GUI and command-line interface, JADX makes it easier for users to explore and analyze the internal logic and structure of Android applications. It is widely utilized for reverse engineering, malware analysis, and security auditing, offering a quick and efficient way to gain insights into an app’s source code.

Here’s a sample of how JADX is used: 

First, run ‘-h’ command.

Next, extract the zip file and simply run the command:
