Since a couple of years Google is offering beta testing for Android apps. With this feature companies or developers have the chance to release Android beta apps to mobile testers via the Google Play Store. This feature is integrated into the Google Play Developer Console and is very easy to use. All you have to do is to upload your beta apk file to the developer console and to publish the app to the known beta testers.
Mobile development teams are able to create their own beta testing community with the help of G+ communities or Google groups. Since last week, Google is offering two more options to improve the beta testing even further. With this update, mobile tester and developer are able to create a public beta tester group without the need of the G+ community or a Google group. All you have to do, is to enable this option in the developer console and to send the beta testing URL to possible testers.
The URL has the scheme: https://play.google.com/apps/testing/com.package.name. Whenever a tester is clicking this link he or she can become a beta tester of the app. After clicking the link, the beta tester will get an update of the app in the Google Play Store and is able to download the beta version.
