How to install Building Construction game v1.1.2 on Android 4.4 KitKat+
Takes about 2 minutes. You'll need roughly 39.9 MB of free storage.
- Grab by.alfasoft.ConstructionGame_200050.apk — hit the Download button above (39.9 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 3c11dcf9abc2e2f5…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find by.alfasoft.ConstructionGame_200050.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=Vladimir Tanakov, OU=Alfasoft BY, O=Alfasoft BY, L=Minsk, ST=Minsk, C=BY. 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 Building Construction game — tap Open on the install screen, or find the Building Construction game icon in your app drawer (this build targets arm64-v8a devices).
Common install errors for Building Construction game
- "App not installed" — usually means an older or differently-signed version is already on your device. Uninstall it first, then retry. Your data may be lost unless you back it up.

- Works on one phone but not another — this build ships arm64-v8a native code. Devices with a different CPU will reject it.
