What is MIME type "application/vnd.android.package-archive"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

The MIME type application/vnd.android.package-archive defines a package used to install Android apps. It bundles all the code, assets, and resources needed for an app to run on an Android device.

Apps are built into a single file container. This container is recognized by Android as a package ready for installation. It is the standard format for side-loading apps outside the official app stores.

Install Android apps: The browser or file manager identifies the package and prompts the installation process.
Distribute apps: Developers use this format to release apps for testing or direct download.
Update management: It can be used to update app components on devices.

The most common file format associated with this MIME type is APK. Other variations that serve similar purposes include XAPK, APKS, and APKM. These variations may include additional data like expansion files or support for multi-APK deployments.

FAQ

What is a MIME type?

A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.

MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.

MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.

How do I find the MIME type for a file?

You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.

Why are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
