【正文】 更多的手機(jī)軟件開發(fā)企業(yè)已經(jīng)或者籌備著將公司進(jìn)行轉(zhuǎn)型 從其方向的開發(fā)轉(zhuǎn)向到 Android 的開發(fā)。底層以 Linux 內(nèi)核作為基礎(chǔ)，由 C 語言開發(fā)，只提供基礎(chǔ)功能。本文概括的介紹了 Android 的 GPS 軌跡記錄軟件設(shè)計 開發(fā)的流程，并重點(diǎn)的介紹了基于 Android 的 GPS 軌跡記錄軟件 平臺 的 開發(fā)過程。這也預(yù)示著GPS 未來在中國的航空、海路、鐵路、建筑、電信、電力等領(lǐng)域的應(yīng)用都會有很大的發(fā)展空間。由于 預(yù)算壓縮， GPS 計劃不得不減少衛(wèi)星發(fā)射數(shù)量，改為將 18 顆衛(wèi)星分布在互成 60 度的 6 個軌道上。 GPS 不僅用于導(dǎo)彈、飛船的導(dǎo)航定位，更是廣泛用于飛機(jī)、汽車、船舶的導(dǎo)航定位，公安、銀行、醫(yī)療、消防等用它建立監(jiān)控、報警、救援系統(tǒng)，企業(yè)用它建立現(xiàn)代物流管 理系統(tǒng)，農(nóng)業(yè)、林業(yè)、環(huán)保、資源調(diào)查、物理勘探、電信等都離不開導(dǎo)航定位，特別是隨著衛(wèi)星導(dǎo)航接收機(jī)的集成微型化，出現(xiàn)各種融通信、計算機(jī)、 GPS 于一體的個人信息終端，使衛(wèi)星導(dǎo)航技術(shù)從專業(yè)應(yīng)用走向大眾應(yīng)用，成為繼通信、互聯(lián)網(wǎng)之后的 IT 第二個新的增長點(diǎn)。由于衛(wèi)星定位顯示出在導(dǎo)航方面的巨大優(yōu)越性及子午儀系統(tǒng)存在對潛艇和艦船導(dǎo)航方面的巨大缺陷。 在網(wǎng)上查找 GoogleMap 相關(guān)的應(yīng)用，查看程序邏輯，是否適合自己的課 題，了解別人的優(yōu)缺點(diǎn)。完成一個這樣有實(shí)用價值的作品，對我以后步入社會后的工作也很有幫助。 在此過程中，不僅調(diào)用了系統(tǒng)提供的控件，也使用了自定義控件。 2,基于 andrion 的 GPS 軌 跡記錄 軟件 設(shè)計 修改 的 Java 虛 擬機(jī) Dalvik， 是基于Apache Harmony 虛擬機(jī)版本進(jìn)行改良而來，能夠提供極高的執(zhí)行性能。s investigation, designs a set of user experience good contact surface. In this process, not only transferred the system to provide controls, also used has controlled from the after the data and the contact surface design, started the system the article, emphatically from the system stability, in the andrion GPS localization, the data lasting and so on the characteristic functions to path recording software development has carried on the brief introduction based on android the platform , after pletes the system the development, has carried on the related issued the system Google android market makes an offering the user downloading the feedback which provides according to the user to this system makes the corresponding the development based on the android GPS path recording software design, understood android moves the 14 platform the performance history and Google android moves the platform the characteristic, develops the process through this contact and the familiar software. The handset has already bee in the life the essential munication equipment, sometimes did not have the handset to be able to let the human think the difficult handset will be separated from the tradition to telephone, to send the short note and so on the basic function, but and might expand ability based on the andrion handset formidable handling ability, based on the 3G work high speed data transmission, more and more many functions and the service is developed and the largescale radical in this, when world vision focusing in this time, GPS in November 5, 20xx announced promotes opens the source handset operating system based on the Linux platform, is known as first for the mobile termination making true development and integrity motion software Android. Android is based on the Linux essence software platform and the operating system, the early time by the Google development, latter (Open Handset Alliance) develops by the opening handset has used the software level (software stack, also names folds level by software) skeleton, mainly divides into three first floor by the Linux essence underlie, by the C language development, only provides the foundation intermediate level including function storehouse Library and virtual machine Virtual Machine, develops by C+.The uppermost layer is each kind of application software, including the voice procedure, the short note procedure and so on, the application software voluntarily develops by various panies, by Java pilation. Not only Android an operating system, it has included: 1, passes through the andrion tailor and evolutionary Linux Kernel, the equipment hardware has provided the outstanding support regarding the palm is undeniable in Linux aspect application ability, andrion Corporation all several hundred thousand servers are pletely oneself has revised the Linux operating systems. 2, Java which revises based on the andrion GPS path recording software design virtual machine Dalvik, is virtual machine edition carries on the improvement based on Apache the Harmony to e, can provide extremely high carries out the the andrion virtual machine, the majority of Java core class storehouse all already might move directly. 3, massive immediately available kind of storehouse and application software, for example browser Webkit, database SQLite, lets you be possible to develop the setoff easily in the tabletop application order of plexity handset software. 4, andrion already developed the good massive readymade application software, simultaneously 15 might use Google to be very many directly the online service. 5, andrion has provided based on the Eclipse integrity development environment, the simulator, the documents, helps, the demonstration will be enormous impels the Android fast promotion and the on the Android GPS path recording software design multitudinous merits, revolved Android to form a motion handset alliance, main ha
