Question 1

What is an XAPK file?

Accepted Answer

An XAPK is an Android package format originating from APKPure that bundles a standard APK together with its OBB data assets in one archive. Installing an XAPK delivers the complete app — base APK, language splits and large game data — in a single step, without copying OBB files separately.

Question 2

What is an APKM file?

Accepted Answer

An APKM is APKMirror's archive format for multi-architecture, multi-language Android app bundles. It packs several split APKs (one base plus per-architecture, per-density and per-language parts) into one container so the right slices for your specific device install from a single file.

Question 3

What is an APKS file?

Accepted Answer

APKS is the file extension used by SAI (Split APKs Installer) and Android App Bundle exports. It is a ZIP-like container holding the base APK plus its configuration split APKs — the same format Play Store delivers but packaged for offline sharing.

Question 4

Is it safe to install XAPK files?

Accepted Answer

Yes, when installed through a trusted tool like X-Installer. XAPKs are installed via Android's official PackageInstaller API, so the system performs signature and permission checks. Only install XAPKs from reputable sources such as APKPure or APKMirror, and avoid files modified by unknown third parties.

Question 5

How large is a typical XAPK file?

Accepted Answer

Most XAPKs range from 40 MB to 1.5 GB. The base APK itself is usually 10–50 MB; the bulk is OBB data for games and heavy assets. Utility apps often ship as XAPKs in the 40–200 MB range; large 3D games can exceed 2 GB.

Question 6

XAPK vs APK — what is the difference?

Accepted Answer

A plain APK is a single installable package, ideal for small apps. An XAPK bundles that APK with its OBB data and split APKs so very large or multi-architecture apps install cleanly in one step. Android's PackageInstaller handles APKs natively; XAPKs need a helper like X-Installer.

Question 7

What is X-Installer?

Accepted Answer

X-Installer is a modern Android app installer supporting APK, XAPK, APKS, APKM, ZIP formats. It uses official Android APIs, is secure and reliable, and requires no root access.

Question 8

What file formats are supported?

Accepted Answer

X-Installer supports APK (standard Android package), XAPK (APKPure format), APKS (SAI format), APKM (APKMirror format), and ZIP (archives containing APKs).

Question 9

Does it require root access?

Accepted Answer

No. X-Installer uses Android's official PackageInstaller API and does not require root access to install apps.

Question 10

Is it safe?

Accepted Answer

Yes. X-Installer uses official Android APIs, complies with Google Play policies, is open source for code review, doesn't collect personal info, and contains no malicious code.

Question 11

Is the app open source?

Accepted Answer

Yes! X-Installer is open source under MIT License.

Question 12

Why does installation fail?

Accepted Answer

Possible reasons include: app incompatibility with your device architecture or Android version, corrupted package, insufficient storage space, or an existing app with the same package name.

Question 13

Why does it need storage permission?

Accepted Answer

X-Installer needs storage permission to access package files. We use two methods: (1) Single File Selection (SAF) — when you manually pick a file, we only access that specific file. (2) Device Scanner — to help you find scattered packages (like XAPKs), we scan shared storage. On Android 11+, this requires "All Files Access". We search for packages locally only and never upload your private data.

Question 14

How to enable "Unknown sources" installation?

Accepted Answer

Android 8.0+: Try installing an APK, tap "Settings", then enable "Allow from this source". Android 7.0: Go to Settings → Security → Enable "Unknown sources".

Question 15

How to use device scanning?

Accepted Answer

Open X-Installer, tap "Scan Device for Packages", wait for the scan to complete, select a package from the list, then tap install.

Question 16

What languages are supported?

Accepted Answer

X-Installer supports 18 languages: English, 简体中文, Español, Français, العربية, हिन्दी, Português, Русский, 日本語, 한국어, Deutsch, Italiano, Türkçe, Tiếng Việt, ไทย, Polski, Nederlands, and Bahasa Indonesia.

Question 17

How to change language?

Accepted Answer

X-Installer automatically uses your system language. To change: go to Settings → System → Languages, select your language, then restart X-Installer.

Question 18

What data is collected?

Accepted Answer

We DO NOT collect personal identification, location, contacts, or SMS/call logs. We collect device info (model, OS version), crash reports, and advertising data through AdMob, AppLovin, Pangle, and Yandex.

Question 19

How to opt-out of ads?

Accepted Answer

Go to Android Settings → Google → Ads → Enable "Opt out of Ads Personalization", or visit Google Ads Settings at adssettings.google.com.

Question 20

What are the minimum requirements?

Accepted Answer

Android 7.0 (API 24) minimum, Android 10.0+ (API 29+) recommended. Supports ARM, ARM64, x86, x86_64 architectures. About 10 MB storage needed.

Question 21

What devices are supported?

Accepted Answer

X-Installer supports all devices running Android 7.0+, including phones, tablets, foldables, and Chromebooks (Android app mode).

Question 22

Does it support batch installation?

Accepted Answer

Not in the current version. This is a planned feature for a future release.

Question 23

Can developers integrate X-Installer into their own app?

Accepted Answer

Yes. X-Installer exposes a public deeplink protocol (xinstaller://install?uri=…) that any Android app can call to hand off split-APK installation. We provide a copy-paste Kotlin helper class with FileProvider setup, format detection and a fallback to Google Play if the user has not installed X-Installer yet.
