In this challenge, you will download an Android application (Android01.apk) and use apktool to extract its contents. The main objective is to retrieve a key that is hidden within the application's configuration files. First, you will extract the apk file using the command `apktool d Android01.apk`, which will decode the apk and provide access to its internal files.

You will then explore critical files such as AndroidManifest.xml and res/values/strings.xml. These files often store essential information about the application and its functionalities. By examining these files, particularly strings.xml, you will find the key needed to complete this exercise. This lab is an excellent introduction to the basics of Android application analysis and reverse engineering.
