- `apt-android-7` variant will set `minSdkVersion=24` (Android `7.0`) and bootstrap installation will fail if installing on Android `< 7`. Normally, APK installation will fail with `INSTALL_FAILED_OLDER_SDK` if trying to install on an old version, or if APK is manually installed in `/data/app`, it should fail to run and app will be disabled/removed on reboot.
- `apt-android-5` variant will set `minSdkVersion=21` (Android `5.0`) and `maxSdkVersion=23` (Android `6.0`) and bootstrap installation will fail if installing on Android `>= 7`. Android does not care for `maxSdkVersion` value and will still allow installation on higher Android versions as the OS provides backward compatibility for apps, but Termux packages do not provide that, so must not be installed on higher Android versions.
This should solve the issue for `0.119.0*` releases showing on F-Droid for Android `5`/`6` users as previously the `apt-android-7` variant was still using `minSdkVersion=21`. Android `5`/`6` releases with `apt-android-5` variant are only to be provided from GitHub.
