問題描述
當(dāng)您在 Eclipse 中創(chuàng)建一個(gè) android 項(xiàng)目時(shí)，您必須選擇使用哪個(gè)平臺(tái)進(jìn)行編譯.您可以選擇 API 17 (Android 4.2) 或 Google API (API 17).
When you create an android project in Eclipse, you have to choose which platform to compile with. You can choose API 17 (Android 4.2) or Google APIs (API 17).
據(jù)我了解，Google API 是 API 17 (Android 4.2)，但具有地圖庫支持和 USB 開放庫.那么如果 Google API 和 Android 一樣，但功能更多……為什么不每次都選擇它呢?
From my understanding, Google APIs is API 17 (Android 4.2), but has the maps library support and usb open library. So if Google APIs is the same as Android, but with more features... why wouldn't you choose it everytime?
Google API 有缺點(diǎn)嗎?我看到的每個(gè)在線教程，他們都使用 API 17(非 Google API).我一直很好奇為什么他們手動(dòng)將其更改為那個(gè)，而不是只使用其中包含更多內(nèi)容的那個(gè).
Is there a downside to Google APIs? Every tutorial online I see, they use API 17 (Non Google APIs). I'm always curious as to why they manually change it to that instead of just using the one that has more in it.
推薦答案
當(dāng)您使用 Google API 運(yùn)行時(shí)，您的應(yīng)用將構(gòu)建為在已安裝 Google 服務(wù)(地圖、USB 等)的設(shè)備上運(yùn)行.如果您絕對(duì)需要這些服務(wù)，則應(yīng)針對(duì) Google API 構(gòu)建，但您的應(yīng)用將無法在未經(jīng) Google 認(rèn)證的設(shè)備上運(yùn)行(即未安裝 Google Play).
When you run with Google APIs, your app is built to run on a device which has the Google services installed on it already (Maps, USB etc). If you absolutely require these services, you should build against Google APIs, but then your app will not run on device which aren't certified by Google (that is, don't have Google Play installed).
如果您確實(shí)想在沒有 Google Play 的設(shè)備上運(yùn)行，并且您的應(yīng)用不需要任何 Google 服務(wù) 100% 存在，那么您應(yīng)該針對(duì)普通的 Android API 進(jìn)行編譯.
If you do want to run on device without Google Play, and your app does not require any of the Google Services to be 100% present, then you should compile against the normal Android APIs.
請(qǐng)參閱此文檔了解更多關(guān)于 Google 對(duì)認(rèn)證設(shè)備的期望.
See this document for a bit more on what Google expects from certified devices.
這篇關(guān)于為什么在 Eclipse 的 SDK 中選擇 Android API 而不是 Google API?的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
