Apk Extractor

Apk Extractor takes an application already installed on an Android device and writes its installation package back out as a file. Android keeps the APK of each installed app on the filesystem, and the tool locates that copy and saves it where the user can reach it. Nothing is downloaded in the process; the source is the package the system installer already placed on the device.

The working pattern is a list of the applications present on the device, followed by extraction to storage. That covers cases such as keeping a copy of a version before it updates, moving an application to a device without a store connection, or handing a package to another tool for inspection.

It is Android-only and bounded by what the platform allows an ordinary app to read, so packages the system does not expose may be out of reach and results vary between Android versions. The code is under the MIT license.
