Android is an open and free operating system based on Linux, which is mainly used for mobile terminals, such as smart phones and panel computer. It is developed by Open Handset Alliance composed of more than 30 technology companies and mobile phone companies. Android tries to allow users experience the best service quality, and allow developers get a more open level for more convenient software developing. Thus mobile applications with more convenient functions can be developed via Android. This paper firstly presents the architecture of Android platform, including the classes and methods in developing. Then we takes audio/video file procurement as an example to introduce the Android program design and development, including classes application, program design, development and analysis. Water is one of the most important commodities which man has exploited than any other resource for sustenance of life . Most of the water on this planet is stored in oceans and ice caps which is difficult to be recovered for our diverse need . The total amount of water on surface of earth is 3.5* 10^20 gallons of which is 97 % is found in sea water while fresh water is only 37 million km^3 . Of this 0.8% occurs in polar ice water while percolates in ground is called ‘Ground Water ’ and it emerges on surface of earth as liver or lake . These are the calculations of amount of water or water sources available for humans . But even though we aren’t able to use this whole water as there is factor of pollution also . The common sources of water pollutions can range from purely natural to several man-made sources like discharge of domestic wastes , industrial wastes(e.g. waste due to sugar factory , Dairy Industry , pulp and paper industry , Textile industry , petroleum Refining , fertilizers , Metal Plating Industry , tanneries , Distilleries , pharmaceuticals , rubber industry , coal washeries) , agriculture wastes etc . Inspite of all these things we are wasting water heavily . The aim of these application is to aware the people about water wastage and to give them information about their water meter number , water timings , pressure and to raise query regrading their water supply digitally using the platform of this application . So that they can use the water in efficient way without wasting it.
