Subject: Restoring provider behavior for reloading app on old devices   > For
 older devices, launcher will only reload in case of inserts with specific
 query parameters   > For older devices, launcehr will notify content
 observers of any internal inserts   > Chaning TAG for Launcher provider as
 max logging tag is only 23 characters
