An app can receive updates if it's installed on a user’s device and is available
according to the Device's policy.
If an app is removed from the
Device's policy, this device will
no longer receive updates for that app.
On-device update settings
You can enforce the update preference by setting policy.autoUpdatePolicy in
the Device's policy.
If you set policy.autoUpdatePolicy to choiceToTheUser or leave it unset,
then the device user can
set update preferences
for their apps from the managed Google Play app. The recommendation is for users
to leave auto updates enabled for all their apps. Note that devices check for
auto updates daily. Because auto updates are optimized for battery life, data
usage, and user experience, it can take up to a few days for a device to receive
an update automatically.
Push updates immediately
If an update to an app is urgent, you can push the update by setting
policy.productPolicy[].autoInstallPolicy.minimumVersionCode in the
Device's policy. If the installed
version has a version code lower than the version code in the policy, an update
to the latest version will be triggered immediately.
