XAPK (Android bundle)
Also known as: XAPK file, .xapk, Android split APK bundle, APK with OBB
An XAPK is a packaging format used by third-party Android app sites to bundle an APK together with its extra data — split APKs or large OBB asset files — in a single download. It is not an official Google format.
- Bundles an APK with split APKs or OBB data
- Unofficial format from third-party app stores
- Needs a special installer; sideload with caution
Why XAPK exists
Some Android apps and games ship as more than one piece: a base APK plus split APKs or large OBB expansion files holding graphics and assets. A plain APK download alone would be incomplete.
XAPK wraps all those parts into one archive so third-party app stores can offer a single file that installs everything together.
Installing XAPK files
XAPK is not supported by Android directly; you need a dedicated installer app from the store that provides the file. It unpacks the APKs and places the OBB data where the app expects it.
Only install XAPKs from sources you trust, since they sideload apps outside Google Play.
