The APK file is used by the Google Android operating system to save installation packages for applications. The APK package store compiles the Android application. It also contains all the resources needed to run Android applications. This can include compilation code, images, text, videos, manifests, certificates, and more.
For general instructions on opening APK files and viewing content, see this guide. Or just change the APK file extension to ZIP or JAR and open it with WinZip, WinRar, 7-Zip or other Unarchiver. Please note that no application from the APK file will be installed. You can only see the internal structure of the APK file.
If you need to install the APK file on Android, Windows or Mac OS, follow these instructions. The APK file cannot be opened on an iOS device. You must find the appropriate application on the Apple App Store or get the application from the developer using the IPA file.
To open an APK file and view individual files, you can use an application that matches the extracted file format. Some resources, such as images, manifests, and XML files, can be easily viewed using your standard Windows or Mac software. However, some, such as compiled source code, libraries, and certificates, require special applications that target this file extension.
Don’t open an APK file from a website that you don’t trust. This allows you to install malicious software on your device.
The APK file format comes from Java Archive File or JAR. For more information about JAR archives, see the JAR file article.
To compress data, the APK file uses the same algorithm as the ZIP file.
APK files are similar to MSI files on the Microsoft Windows platform, DMG files on the Mac OS platform, and IPA files on iOS. All file formats above are used to install software in packages.
