How to install SQL Reference v2.3 on Android API 7+
Takes about 2 minutes. You'll need roughly 927.6 KB of free storage.
- Grab com.a4droid.sql_reference_8.apk — hit the Download button above (927.6 KB). If your browser warns about APK files, choose Keep or Download anyway — that warning fires on every APK, not just this one.
- Trust your browser to install — on Android 8+ go to Settings → Apps → Special access → Install unknown apps, pick the app you downloaded with (Chrome, Firefox, Files, etc.), and flip Allow from this source. On older Android, toggle Unknown sources under Security.
- (Optional) Verify the file — compute the MD5 of the downloaded APK and make sure it matches 61b130f533cf5bdc…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find com.a4droid.sql_reference_8.apk in your Files app under Downloads, then tap it. Android's package installer will appear.
- Check the signer — the install screen will name the publisher. For this build it should read CN=Sergey Ivanov, O=A4DROID, L=Moscow, C=RU. If it doesn't match, cancel — you have the wrong file.
- Review permissions & tap Install — scroll the permission list, then confirm. If Play Protect flags it, tap Install anyway (this APK was scanned as WARNING).
- Done — open SQL Reference — tap Open on the install screen, or find the SQL Reference icon in your app drawer.
Common install errors for SQL Reference
