Description
Technical field
The present invention relates to digital education technical field, particularly relate to a kind of education based on android mutual
The method realized and system thereof.
Background technology
The Ruan Yin operator etc. of Apple, Amazon Company and Japan is carrying out energetically at present
Panel computers such as iPad/Kindle, and carry out pilot in education sector, in the U.S., some are little at present
/ middle school has been achieved with greater advance；The company such as Google utilizes cloud computing technology to wish books simultaneously
Shop, book contents are all put on cloud, thus Formation education cloud, books cloud and courseware cloud etc., mesh
Front Google company has been proposed that digital library's business.Additionally France of Japan is utilizing new model terminal
The industry such as digital art, digital education is advanced with cloud computing technology.
Android is the shifting of increasing income based on Linux platform that Google announced on November 05th, 2007
The title of dynamic operating system, this platform is by operating system, middleware, user interface and application software group
Become.It uses the framework of software stack layers (Software Stack has another name called software lamination), is broadly divided into
Three parts.Bottom, based on linux kernel works, is developed by C language, is provided only basic function；
Intermediate layer includes function library Library and virtual machine Virtual Machine, C++ develop.The superiors
Being various application softwaries, including voice procedure, note program etc., application software is then by each company voluntarily
Exploitation, using Java as a part for coding.There is not any conventional obstruction and move re-invent industry
Patent rights obstacle, being known as is the first real open and complete mobile software made for mobile terminal.
Google by with other each side concerned such as soft and hardware developer, equipment manufacturers, telecom operators
Form the partnership relation of profound level, it is desirable to soft by Criterion, open mobile phone
Part platform, forms an open ecosystem in mobile industry.Android is as Google
The important component part of corporate strategy, will be pushed further into " providing information for everyone whenever and wherever possible " this
The realization of business goal.The plurality of mobile phone user in the whole world is currently in use various based on Android
Phone.The target of Google is to allow (mobile communication) not rely on equipment even platform.For this
Purpose, Android will supplement, without substituting the mobile development strategy that Google follows for a long time: logical
Cross mobile-phone manufacturers and mobile operator with all parts of the world and form affiliate, develop the most useful but also have
The Information Mobile Service of captivation, and promote these products.
Making a general survey of the development path of Internet industry, TV, newspaper, library, marriage are situated between by it
Continue institute, department store, service for life etc. all moves on network, and next step is exactly these network industries
Business is put in pocket (mobile Internet), it is achieved all things in Mobile, thus realizes whenever and wherever possible
Mobile business.Therefore, all trades and professions are installed to mouth by the development trend of whole Internet industry exactly
In Dai, Novel mobile terminal and cloud computing is utilized to carry out industrial integration.Therefore, the mobile Internet epoch
Novel intelligent terminal technology and cloud computing technology brought new business opportunity and choosing for education industry
How war, realize the integration of education industry based on android technology and cloud computing technology and industry translated
Through becoming one of topic of educational circles and Internet circles' terminal care.The interconnection networking of education industry and shifting
Dynamic the Internet is inevitable development trend, and it has the wireless wide market space and development opportunity, and
And industry development at present is scarcely out of swaddling-clothes.How to realize andriod technology to the mutual span of interaction,
Also need to design a kind of new technology mode enter in interactive mode.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, the invention provides a kind of based on
