android update play store -

I have a private app that is not on the Google Play store and will not be released.

I need an instrument to renew an app when the update is released, is there a library that makes over-the-air (OTA) updates easier to push from my server?

I have been looking for the simplest solution so far on my search I have not found any helpful results.

I can think that the best approach is a PHP that does DB lookup. Every time you release a new version, you store this new version. Then your web server may have a scheduled task to run PHP scripts that do DB lookup and if a new version is found then Google sends information to the user through cloud messaging (GCM), so that your app Listens to display notification

Simple solution, if you do not want to worry about using GCM, a PHP script again, which is your end Can post Oid app, say every day, and PHP script lookup and returns gives a new version and the URL for the new version of your app can ask the user whether to download the app.
