"ANDROID 101"

Android 101 keeps apps up to date.
Android has had automatic updating of apps through the Play Store,and it's a simple process to get set up.
head to the GOOGLE PLAYStore on your device, hit the menu button and go to "settings". If it isn't already set by default, go ahead and tap the "Auto-update apps" setting and choose the most appropriate setting for your needs -- no updates, updates only on Wifi, or all updates. Most people with limited data buckets will be best-off with the "Auto-update apps over Wifi only" option. Once you have turned on automatic updates of either kind, you can always turn off automatic updates for a particular app by navigating to its Play Store listing (from the "My apps" area) and tapping the menu button, then un-checking the "Auto-update" box.
