Does the app check android version and give a unsupported message?
For the beta, even if you had the package file, it wouldn't install on anything less than 4.4, giving some sort of spurious error such as 'parse error'. I'm sure that the Google Play Store will not let you select and install the app if its not compatible with your device.
