How to install C3A, Council for Third Age v1.7.15 on Android 5.0 Lollipop+
Takes about 2 minutes. You'll need roughly 12.2 MB of free storage.
- Grab sg.org.nsa.courseapp_33.apk — hit the Download button above (12.2 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 9a8ff3c720910ac3…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find sg.org.nsa.courseapp_33.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=Vinova, OU=Vinova, O=Vinova, L=Ho Chi Minh, ST=Ho Chi Minh, C=84. 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 C3A, Council for Third Age — tap Open on the install screen, or find the C3A, Council for Third Age icon in your app drawer.
