DEVELOPMENT
Update Schedule
• Google provides major updates, incremental in nature, to Android every six to nine months, which most devices are capable of receiving over the air.
Android is developed in private by Google until the latest changes and updates are ready to be released, at which point the source code is made available publicly.
• When an Android app is no longer in use, the system will automatically suspend it in memory. while the app is still technically
"open," suspended apps consume no resources (e.g. battery power or processing power) and sit idly in the background until needed again.
This source code will only run without modification on select devices, usually the Nexus series of devices
Memory management
• Android devices are usually battery-powered, Android is designed to manage memory (RAM) to keep power consumption at a minimum, in contrast to desktop operating systems which generally assume they are connected to unlimited mains electricity.
Linux
• Android consists of a kernel based on Linux kernel version 2.6 and, from Android 4.0 (Ice Cream Sandwich) onwards, version 3.x
• The latest major update is Android 4.3 Jelly Bean, released on July 24, 2013; 7 days ago
• The new Nexus 7, Google's in-house Android tablet, is shipping next week with the 4.3 version of system software and features preinstalled
