And with the new technologies, new computer code and operative systems area unit needed.

Operating Systems have developed plenty in last fifteen years. ranging from black and white phones to recent good phones or mini computers, mobile OS has come back isolated. particularly for good phones, Mobile OS has greatly evolved from Palm OS in 1996 to Windows pocket laptop in 2000 then to Blackberry OS and humanoid.
One of the foremost wide used mobile OS of late is humanoid. humanoid could be a software system bunch comprising not solely software however conjointly middleware and key applications. humanoid INC was supported in Palo Alto of CA, U.S. by Andy Rubin, Rich miner, Nick sears and Chris White in 2003. Later humanoid INC. was non heritable by Google in 2005.
once original unharness there are variety of updates within the original version of humanoid.
Features & Specifications

• every element performs a unique role within the overall application behavior, and every one may be activated one by one (even by alternative applications)
• The manifest file should declare all parts within the application and will conjointly declare all application necessities, like the minimum version of humanoid needed and any hardware configurations needed
• Non-code application resources (images, strings, layout files, etc.) ought to embody alternatives totally different|for various} device configurations (such as different strings for various languages)

Google, for software system development and application development, had launched 2 competitions ADC1 and ADC2 for the foremost innovative applications for humanoid. It offered prizes of USD ten million combined in ADC1 and a pair of. ADC1 was launched in Jan two008 and ADC 2 was launched in might 2009. These competitions helped Google plenty in creating humanoid higher, additional user friendly, advanced and interactive.
