APK Files on Android

The full process for installing an app from a downloaded .apk file instead of the Play Store -- enabling installs from unknown sources, running the installer, and what to do if Android blocks it.

Target: Android 8.0+AndroidSideloadingOfficial homepage ↗Official docs ↗
This guide is synthesized from APK Files on Android's own official documentation, linked above — always cross-check exact package/version names there before running these commands on a production server, since distro and project versions move over time.

  1. 1Download the APK to your device

    Use your device's own browser (not a desktop browser) so the file lands directly on the phone/tablet -- if you downloaded it on a computer, transfer the .apk file over first (USB cable, or send it to yourself another way).

  2. 2Allow installs from this source

    Android 8.0+ grants the "install unknown apps" permission per app (e.g. per your browser or file manager), not as one global toggle. Tap the downloaded APK -- Android will prompt you directly to allow it for that app if it isn't already.

    Settings > Apps > Special app access > Install unknown apps

    You only need to allow this for the ONE app you're installing through (your browser or file manager) -- there's no need to leave it enabled for apps you don't recognize.

  3. 3Tap the APK file and confirm the install

    Android shows the permissions the app requests before installing -- review them, then tap Install.

  4. 4If Google Play Protect blocks or warns about it

    See the separate "Understanding Google Play Protect warnings" guide in this section for what these warnings actually mean and how to check whether it's safe to proceed.
