Title Realization of Mobile Phone Power Measurement
Method Based on Android Operating System
Abstract
Along with the development of society, the number of mobile phone users has exceeded the number of PC machines in the Globe.And the number of mobile phone users is growing fast. Intelligent mobile phone accounts for the proportion to grow with each passing day. And the emergence of mobile phone based on android opration system brings a breakthrough in the field of intelligent mobile phone.Because Android is based on the Linux kernel and has the feature of open source, free of charge, it quickly get the the support of users and vendors. So learning the development of application software based on Android opration system is necessary and conform to the trend of the time.
This paper first study the four components of android system, and then
leran the development of applications in detail with the example of designing and realizing a power measurement app. This application is realized using the Java programming and Eclipse editing tools, and can run independently in the AVD and Android moblie phone. At the same time, the paper also presents detailed process of designing, part of the interface diagram and main operation flow chart. This power measurement software achieves not only realizes the real-time statistical energy function, but also shows the details of cell.
