How to Install XAPK, APKS & Split APK Files on Android

Downloaded an .xapk or .apks file and Android won't open it? That's normal — the built-in installer only handles plain .apk files. This guide shows the fastest way to install XAPK, APKS, APKM, OBB and split APK files in one tap, on any Android phone, TV or tablet — no root and no PC required — plus fixes for when an XAPK won't install.

What is an XAPK file?

An XAPK is a ZIP-style bundle that packs an app's base APK together with its split APKs (extra code, languages or screen-density resources) and, for many games, an OBB expansion file holding large assets. Modern apps on Google Play are delivered this way through the Android App Bundle, so when you download an app outside the Play Store you often get an .xapk or .apks file instead of a single .apk.

The catch: Android's built-in package installer only understands a single .apk. Hand it an XAPK and nothing happens. To install one, you need a small helper app that unpacks the bundle and installs every part into the right place — that's what an XAPK installer does.

How to open an XAPK or APKS file

For these files, "open" and "install" are the same action. Tapping an .xapk in your file manager gets you nowhere on its own — Android registers no default handler for the format, so the system has nothing to hand it to. What you actually see varies: on a stock Pixel you get an Open with sheet listing apps that can't install anything (Google, Google Wallet); other phones show "Can't open file", and some fall back to a ZIP viewer, which unpacks the parts but installs none of them.

To actually open one, give it to an app that understands the bundle:

• From the installer — open SAI+ (or any split-APK installer), browse to the file and tap it there. This is the route that always works.
• From a file manager — long-press the .xapk or .apks file, choose Open with, and pick the installer. If it isn't offered, the installer hasn't registered for that file type on your device; use the route above instead.
• Just to look inside — rename the file to .zip and open it with any archive app. You'll see the base APK, the split APKs and any OBB folder — but nothing is installed this way.

Opening an .apks or .apkm file works exactly the same way — see APKS, APKM & split APKs below.

The easy way: install an XAPK in one tap

The simplest method is a dedicated installer that reads the whole bundle and does the work for you. We build a free one called SAI+ (Split APKs Installer) — it installs XAPK, APKS, APKM, AAB, OBB and split APK files with a single tap, works fully offline, needs no root or PC, and shows only a small banner ad rather than the full-screen ads most installers push.

Step-by-step: install an XAPK file

1. Download the .xapk (or .apks) file

   Save it to your phone — the Downloads folder is fine. Note where it lands so you can find it in the next step.

2. Install a free XAPK installer

   Get SAI+ (or any trusted installer) from Google Play and open it.

3. Allow "Install unknown apps"

   When prompted, let the installer install apps. On Android 8 and newer this is a per-app switch under Settings → Apps → Special access → Install unknown apps.

4. Select your file and tap Install

   In the installer, browse to the .xapk file (or just tap the file in your file manager and choose the installer). It unpacks the base APK, split APKs and OBB data automatically.

5. Open the app

   When it finishes, tap Open. That's it — no PC, no root, no manual unzipping.

Install an XAPK on Android TV, Fire TV or Firestick

Streaming devices run Android too, so the same idea works — you just need a way to move the file over and a file browser. On Fire TV / Firestick, enable Settings → My Fire TV → Developer options → Apps from Unknown Sources, use a sideloading tool (such as the Downloader app) to fetch the file, then open it with an installer that supports split APKs. On Android TV / Google TV, enable unknown sources for your file app under Settings → Apps → Security, then install as above.

Installing APKS, APKM and split APK files

These are close cousins of XAPK and install the same way:

• .apks — the output of Google's bundletool; a set of split APKs zipped together. Open it with a split-APK installer.
• .apkm — APKMirror's bundle format. Most modern installers, including SAI+, read it directly.
• split APK folder — sometimes you get loose base.apk + config.*.apk files. A split-APK installer lets you select them together and installs them as one app.

The key point: all of these contain multiple APK parts, which is exactly why the stock installer refuses them and a bundle-aware installer is needed.

Can't install XAPK? Common fixes

If an XAPK won't install, work through these in order — one of them almost always solves it:

• "Install unknown apps" is off — turn it on for the specific installer app (not just globally). This is the number-one cause.
• Missing storage permission — grant the installer access to files/storage so it can read the bundle and write OBB data.
• An older version is already installed — if the existing app was signed with a different key, uninstall it first, then install the XAPK.
• Corrupted or partial download — re-download the file; an interrupted download produces an invalid ZIP that fails to unpack.
• Not enough free storage — XAPKs with OBB data can be several GB once extracted. Free up space and retry.
• "App not installed" on Xiaomi/MIUI — disable MIUI optimization in Developer options, and turn off the "scan apps before installing" prompt during the install.
• Wrong architecture — a split APK built only for arm64 won't install on a 32-bit device. Get the build that matches your phone.

Errors you might see, word for word

If your installer or the download page showed one of these exact messages, here is what it means:

• "You have to select at least one architecture split file" — the bundle ships several ABI splits (arm64-v8a, armeabi-v7a, x86_64) and none of them was ticked, so the app would be installed without any native code. In SAI+, open the file, expand the split list and select the ABI that matches your phone — arm64-v8a on almost every device made in the last several years — along with your screen density and language.
• "Attention! You are downloading an (APKS / APK split / Android App Bundle) file. Please read the installation instructions." — this is the notice APKPure and similar sites show before the download starts. It is not an error and nothing has failed: it only means the file is a multi-part bundle rather than a plain .apk, so Android's built-in installer can't open it. Finish the download, then open the file with a split-APK installer as described above.

Is it safe to install XAPK files?

The XAPK format itself is safe — it's just a container, no more dangerous than a ZIP. What matters is where the app inside came from. An installer unpacks and installs the bundle; it does not scan the app or make an untrusted APK safe. So the honest rule is simple:

• Only install XAPKs from a developer or store you already trust.
• Be wary of "mod", "premium unlocked" or cracked builds — that's where malware usually hides, not in the format.
• Keep Google Play Protect enabled; it scans sideloaded apps as an extra layer.

A trustworthy installer keeps out of your way: no account, minimal permissions, and it doesn't quietly install anything extra.

XAPK vs APK: what's the difference?

An .apk is one complete package, and Android installs it on its own. An .xapk is that same APK plus everything Google Play would normally deliver alongside it — the split APKs (extra languages, screen densities and CPU code) and, for large games, the OBB data — all zipped into a single file. Same app, more parts.

That one difference explains the rest: because an XAPK holds several pieces, the stock installer refuses it and you need a bundle-aware installer to unpack and place each part correctly. Nothing about the format makes the app itself different, bigger or less safe — it is packaging, not content.

Also: APKS vs APKM vs AAB

In short: .apk installs on its own; .xapk, .apks and .apkm all need a bundle-aware installer; and .aab is meant for developers, not end users.

Installing an XAPK on PC or iPhone?

XAPK is an Android format. You can't run it on an iPhone or iPad — iOS uses a completely different app system. On a Windows PC or Mac, an XAPK only runs inside an Android emulator (such as one built on Android); on a Chromebook with Play Store support you'd install it through the Android subsystem. For an actual phone or tablet, the one-tap method above is all you need.
