android apk non-market install update notification

We have users with android app installed from non-market install(manual apk inst开发者_如何学运维all)

Also we have updated app on market place.

Will Android market send notification to user saying "new version available" on phones where app is installed manually?

The answer is NO. Applications which are not installed from Android Market will not get update notification from Android Market. You must implement your own update notification mechanism within your app.

If user opens market and search for the app it shows as upgrade, market checks if the version installed on the device is same as what is there on the market. I am not sure about the automatic notification behaviour, i think it does but i saw this behaviour randomly sometimes it comes up after a hr , sometimes in a day.
