????根據(jù)應(yīng)用程序分析公司Flurry的說法，開發(fā)者開發(fā)iOS應(yīng)用程序的時(shí)間僅為安卓的一半。而在回報(bào)方面，他們從iPhone用戶身上取得的收入是安卓用戶的足足四倍。Flurry指出，這樣的差距舉足輕重，“如果開發(fā)者社區(qū)選擇投向一個(gè)平臺，那么開發(fā)者們所打造的軟件將能無限提升其用戶體驗(yàn)價(jià)值，這將給予該平臺顯著優(yōu)勢。”

????安卓不僅面臨著由于開發(fā)繁瑣，開發(fā)者紛紛逃離的問題，而且，伴隨RIM旗下黑莓的衰敗， iPhone正侵入企業(yè)市場。高德納最近的報(bào)告指出，由于需要管理眾多設(shè)備和不同版本的操作系統(tǒng)，安卓在大企業(yè)的應(yīng)用“嚴(yán)重受限”。

????當(dāng)然，谷歌大部分收入來自廣告。安卓的用處在于它提供了一個(gè)現(xiàn)成的平臺，來展示這些廣告。但正當(dāng)谷歌在其它平臺面臨新威脅之時(shí)，安卓似乎正在變?nèi)?。本周，蘋果與其開發(fā)者召開會議，在會上推出了自己的針對iPhone的地圖應(yīng)用，以取代谷歌。蘋果還將Facebook功能融入iOS 6，這可能會打擊谷歌在社交網(wǎng)絡(luò)方面的努力。

????這并非意味著安卓氣數(shù)已盡。雖然IDC預(yù)測安卓的市場份額將下降，但該公司也承認(rèn)安卓在未來幾年仍將是領(lǐng)先的移動平臺。不過，安卓明顯面臨諸多挑戰(zhàn)，會減緩其在過去幾年令人印象深刻的增長勢頭。如果出現(xiàn)這種情況，谷歌從智能手機(jī)用戶身上賺錢的錢計(jì)劃可能會碰釘子，該公司將不得不在移動互聯(lián)網(wǎng)領(lǐng)域另起爐灶。

????According to app-analytics firm Flurry, developers build two iOS apps for every Android app they create. In return, they make four times as much revenue from iPhone users than from Android users. That discrepancy is crucial because, as Flurry noted, "If the developer community embraces one platform over the other, developers will build the software that infinitely extends the value of the consumer experience, giving a platform a meaningful edge."

????And it's not just developers put off by the complexity of working with Andriod. while the iPhone has made inroads into the enterprise market -- at the expense of Research-in-Motion's (RIMM) Blackberry -- a recent report by Gartner showed Android is "severely limited" in large companies because of the work involved in managing these same variations in devices and OS versions.

????Of course, Google makes most of its money from ads. Android is helpful insofar as it provides a ready-made platform for serving those ads. But Android seems to be peaking just as Google is facing new threats on other platforms. As Apple holds a conference with its own developers this week, it's expected to announce its own mapping app for iPhones, displacing Google. Apple may also integrate Facebook functionality into iOS 6, which could sideline Google's efforts in social networking. (Follow along with Apple's announcements live.)

????None of this means Android is going away. IDC, which predicts a falling market share for Android, still sees it at the leading mobile platform for years to come. But there are enough clear challenges before Android to slow its impressive momentum of the last few years. If that happens, Google's plans to make money from smartphone users could hit a snag, and the company will have to get creative about the mobile web.
