How to install Learning Polish language (less v15 on Android 4.4 KitKat+
Takes about 2 minutes. You'll need roughly 10.3 MB of free storage.
- Grab polish.courses.offline_15.apk — hit the Download button above (10.3 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 46872ac6370a1e69…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find polish.courses.offline_15.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=Android, OU=Android, O=Google Inc., L=Mountain View, ST=California, C=US. 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 Learning Polish language (less — tap Open on the install screen, or find the Learning Polish language (less icon in your app drawer.
