# APK Reverse Engineering to get Source code of Android Application

Reverse engineering is a technique called **decompiling** that involves examining a mobile app’s source code for analysis. The binary is examined by decompiler software, which transforms the contents from a low-level abstraction to a higher-level abstraction.

Reverse engineering is the act of disassembling anything in order to figure out how it operates, whether it’s a lock or, in this instance, a mobile application.

An Android binary is called an APK, which stands for Android Package Kit. The APK contains application data in the form of **zipped Dalvik Executable (.dex) files.**

> A decompiler is a tool that uses the APK’s contents to try to reveal the original code that was used to create the app’s many capabilities. The decompiler may occasionally fail to reverse a tiny portion of the program, even though this procedure is generally consistent.

***Getting Started with APK Reverse Engineering :***

**Step 1:** Get the APK for the application you just deployed.

**Step 2:** You must now visit the specified website to determine if the APK has been decompiled or not.

**Step 3:** You may enter **apk decompile** and select the first link, as seen in the image below.

Upload and Decompile

**Step 7:** You must now wait until the procedure is finished, as shown in the screenshot below.
