【正文】 to obtain information. Services of mobile Phone will have great development space,Phone Guardian is one of them. Android platform offers users very convenient Campus Information the function， This will be for Phone Guardian the design and implementation of service provides a better addition, Android platform is basically opensource and free, so can effectively reduce the software costs, Finally let each user will be free to get information, Also for the popularization of mobile phone Campus Information the service contribution. This paper discusses the present application of Symbian, Windows Mobile, MacOSX and RIM situation of such platform are analysed and pared. Further research and analysis of the Android platform system architecture and the ponent model, then analyzes the important Android API and the application form, with Intent and life cycle mechanism, on this basis, design and development of mobile phone Phone Guardian the software based on the Android platform. This system friendly interface, Convenient operation, Has good expansibility and maintainability。在此基礎(chǔ)上，基于 Android平臺設(shè)計(jì)和開發(fā)的手機(jī)衛(wèi)士軟件。 本文對目前應(yīng)用的 Symbian、 WindowsMobile、 MacOSX 和 RIM 等平臺的現(xiàn)狀進(jìn)行了分析與比較。 Android 平臺提供給用戶非常方便的數(shù)據(jù)查閱功能，這將為手機(jī)安全衛(wèi)士軟件的設(shè)計(jì)與實(shí)現(xiàn)提供了更好的平臺。 畢業(yè)設(shè)計(jì)（論文） 說明書 論文名稱： 基于 android的手機(jī)衛(wèi)士的開發(fā) 2020 年 10 月 I 摘 要 隨著智能手機(jī)一步步走進(jìn)普通人的生活，它將成為人們獲取信息的主要設(shè)備。因此，手機(jī)的娛樂應(yīng)用服務(wù)將會有很大的發(fā)展空間，手機(jī)衛(wèi)士就是其中之一。另外， Android 平臺基本上是開源、免費(fèi)的，所以能夠有效降低軟件的成本，最終讓每個用戶能夠自由地獲取信息，也為手機(jī)軟件服務(wù)的普及做出貢獻(xiàn)。進(jìn)而研究分析了 Android 平臺的系統(tǒng)架構(gòu)和組件模型，接著解析了 Android中的重要 API 和應(yīng)用構(gòu)成，以 Intent 和生命周期的機(jī)制。本系統(tǒng)界面友好、操作便捷，具有良好的可擴(kuò)展性和可維護(hù)性；系統(tǒng)經(jīng)過測試，可以穩(wěn)定運(yùn)行，能夠滿足手機(jī)用戶的基本需求。 after test of system, can stable operation, To meet the basic needs of mobile phone users.
