What Is an APK and How Does It Work?
Learn what an APK file is, what it contains and why Android uses APK packages to install applications.
What does APK mean?
APK stands for Android Package Kit. It is a package format used to distribute and install Android applications.
An APK contains application components and information required by Android to install the application.
What can an APK contain?
An APK can contain application code, resources, assets, configuration information and a manifest describing important application details.
The package is signed so Android and distribution systems can identify and verify the application publisher and release.
Should you download APK files from anywhere?
No. APK files obtained from unknown or untrusted sources can create security and privacy risks.
Whenever possible, use the official app store or the application developer’s official distribution channel.
