Can’t Install Tachiyomi on Android? 9 Quick Fixes That Work

Having trouble installing Tachiyomi on your Android device? Don’t stress. Use the step-by-step fixes below, plus a pro tip at the end to avoid future install headaches.

Before you start: Make sure you’re installing a compatible and up-to-date build of Tachiyomi or a fork.

• Download the latest stable build: Tachiyomi v0.15.3
• Prefer a fork? Follow this: Tachiyomi J2K Installation Guide (2025)
• Need the main APK hub? Go to the Tachiyomi APK homepage

Why Tachiyomi Won’t Install (And How to Fix It)

1) Check Your Storage Space

• Go to Settings > Storage and ensure you have at least 200–500 MB free.
• Clear Downloads, large videos, or unused apps if you’re low on space.

2) Clear Package Installer and/or Play Store Cache

• For sideloaded APKs: Settings > Apps > Show system apps > Package Installer (or “Android Package Installer”) > Storage > Clear cache and Clear data.
• If you’re installing via Play Store (for other apps/forks): Settings > Apps > Google Play Store > Storage & cache > Clear cache and Clear data.

3) Allow Installs from Unknown Sources (APK Sideloading)

• Android 8.0+: Settings > Apps & notifications > Special app access > Install unknown apps > choose your Browser or Files app > Allow from this source.
• Android 7.1 or lower: Settings > Security > Unknown sources (enable). Remember to disable it after installation for safety.

4) Check App Compatibility (Android Version + CPU Architecture)

• Some builds require newer Android versions. Compare your device version with the notes on Tachiyomi v0.15.3.
• If you’re using split APKs (APKM, APKS, XAPK), install with a split-aware tool (see the Bonus Tip below).

5) Remove Conflicting or Previously Signed Builds

“App not installed” often appears if a different build with the same package name is already installed (signed with a different key).

• If you can open the old app: back up first (Tachiyomi > Settings > Backup & Restore).
• Uninstall the conflicting version, then install the new APK.
• If you prefer a fork with a different package name, see: Tachiyomi J2K Installation Guide (2025)

6) Restart Your Phone

A simple reboot clears temporary installer issues and background lockups.

7) Re‑download the APK from a Trusted Source

• Corrupted or incomplete downloads cause installation failures.
• Re-download from your trusted source or your preferred release page. You can also start from the Tachiyomi APK homepage.

8) Temporarily Disable Play Protect (Optional, Advanced)

If Play Protect flags the APK:

• Open Google Play > Profile > Play Protect > Settings > turn off “Scan apps with Play Protect.”
• Install Tachiyomi, then re-enable Play Protect immediately.

9) Use a Third‑Party Installer or ADB (Advanced)

• Third‑party installers like APKMirror Installer or Aurora Store handle split APKs and give clearer error logs.
• ADB method (for power users): Enable Developer options + USB debugging, then use “adb install yourfile.apk” from a computer.

Bonus Tip: Use a Third-Party App Manager

If you install APKs frequently, a reliable app manager can:

• Validate APK integrity and compatibility
• Handle split APKs
• Show readable error logs
  Tools like APKMirror Installer or Aurora Store can save time and reduce install errors.
