How to install Construction Industry Helpline v4.0.0 on Android 5.0 Lollipop+
Takes about 2 minutes. You'll need roughly 58.7 MB of free storage.
- Grab com.coins_global.buildingbuddy_39.apk — hit the Download button above (58.7 MB). 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 9bae768940e6dcf6…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find com.coins_global.buildingbuddy_39.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=Ana Lameira, OU=COINS-Mobile, O=COINS, L=London, ST=London, C=UK. 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 TRUSTED).
- Done — open Construction Industry Helpline — tap Open on the install screen, or find the Construction Industry Helpline icon in your app drawer (this build targets x86-64/arm64-v8a devices).
