How to open .AAR files on Android
To open .AAR files on Android, android typically won’t “open” AARs as apps; to inspect contents, move it to a desktop and open it as a ZIP, or use it only as a library dependency in an Android development environment.
Step-by-step instructions
- Android typically won’t “open” AARs as apps; to inspect contents, move it to a desktop and open it as a ZIP, or use it only as a library dependency in an Android development environment.
Common issues
It won’t open (or opens in the wrong app)
Many systems don’t associate .aar with a viewer. An AAR is a ZIP-based library package, not a document or installer, so double-click behavior is inconsistent.
- Make a copy of the file and rename the extension from .aar to .zip.
- Open/extract it using any ZIP-capable archive tool, then inspect files like AndroidManifest.xml, classes.jar, and res/.
Expecting an app installer or executable
AAR is a library distribution format for Android builds; it is not an APK and cannot be installed or launched on a device.
- If you need to install something on Android, you likely need an .apk, not an .aar.
- If you are developing, add the AAR as a dependency in your Android Studio/Gradle project per Android’s library documentation.
The file looks like a ZIP but tools complain it is corrupted
Because AAR is a ZIP container, partial downloads or modifications can break the archive structure and cause extraction errors.
- Re-download or re-copy the AAR to ensure the transfer completed successfully.
- Try extracting with a different ZIP tool; if multiple tools fail, the archive is likely damaged.
Security note
An AAR is a ZIP-based archive and can bundle compiled code (for example, classes.jar). Treat AARs from untrusted sources like any third-party library: using them in a build can introduce untrusted code into your app.
