How to Share and Install APK Files Safely
Last updated: October 26, 2026
An APK is the installer file for an Android app. People share APKs to move an app to
a phone without Play Store access, to test their own builds, or to keep an older version.
Because an APK can run code on the receiving phone, it deserves more care than a photo.
For the sender
- Only share APKs you built yourself or have the right to distribute. Redistributing
paid or copyrighted apps breaks our Terms and usually the law.
- Use a one-time link with a pairing code so the file can't be picked up by
anyone else who sees the QR.
- Tell the receiver the app's version number so they can check what they got.
For the receiver
- Know the source. Install only APKs from someone you trust.
- Check integrity. AndroidDrop's browser receiver verifies every file's
SHA-256 hash after download, so you know the file wasn't corrupted in transit.
- Allow the install for one app only. Android asks you to allow
"Install unknown apps" for the app that opens the APK (your browser or file
manager). Turn it back off afterwards in Settings → Apps → Special
app access.
- Let Play Protect scan it. Keep Google Play Protect enabled; it scans
sideloaded apps before install.
- Review permissions. A flashlight app has no reason to read your SMS.
AndroidDrop never installs an APK automatically. Installing is
always your decision.
