Open the APK inside an Android app
- Check Android app support. Open Settings → Apps → Manage Google Play preferences. If that option is absent, use the Crostini tab for the Linux app instead.
- Install an Android file manager. Open the Google Play Store and install AnExplorer.
- Open the downloaded APK. Launch AnExplorer, open Downloads, and select
Conways-Game-Of-Life-Lab-3.0-ChromeOS.apk. Open it inside AnExplorer rather than the ChromeOS Files app. - Allow this source if offered. If the Android installer asks, choose Settings and enable Allow from this source for AnExplorer. You may also find it in Manage Android preferences → Apps → Special app access → Install unknown apps; labels vary by Android version.
- Install and open. Return to AnExplorer, select the APK again, and choose Install. Open the app from the ChromeOS Launcher when installation finishes.
