What is APK Decompiler?

Android users frequently hear the word 'APK'. 'APK' is short for Android Package Kit, and this is a file format that the Android system uses to distribute and install apps in an organized manner. This file package contains all the required elements for an Android application to function properly. An APK is an archive, like ZIP files or TAR files, and contains multiple files, including the file which contains vital metadata about the application. When you download an APK file on your Android device, and install it, the Android system installs the application, without error, due to the mannerisms of the APK file. Sometimes, you might wonder what is actually inside an APK file. An APK de-compiler is the perfect tool to help you uncover the contents of an APK file.

The UnboxAPK de-compiler is one of the best tools for uncovering the contents of an APK file and understand how an APK allows the application to operate correctly. To decompile any APK file, all you have to do is upload your APK file to the platform above, where it says 'Upload'. The de-compiler will take care of the rest, and start unraveling the contents of the APK file. Depending on the size and the contents inside the APK file, the time required to complete the de-compilation process varies. If the size of the APK file is small, the de-compilation process will take only a few seconds. The maximum size limit (at the moment) for the de-compiler is 100 MB.

Once the APK has been de-compiled, you can download the zipped file containing the de-compiled files through the UnboxAPK API. There are various ways to view the de-compiled files, and one of the best ways is to use Android Studio.

Currently, the UnboxAPK website only supports de-compiling Android applications. The capability to de-compile iOS applications will soon follow. The UnboxAPK decompile is powered by jadx.
