2、編譯前的準(zhǔn)備工作，配置JDK1.5環(huán)境(使用最新的JDK1.6反倒是編譯不過去)
在Android中使用谷歌自己開發(fā)的Java虛擬機內(nèi) 核技術(shù)(JVM),稱為Dalvik,該Java虛擬機在Android手機上執(zhí)行Java程序. 谷歌表示,即使在手機的限制性硬件上,Dalvik也能使Java程序運行得很快.與我們通常使用的Java虛擬機的一個顯著的區(qū)別就是, Android并不屬于Sun公司在1999年成立的Java標(biāo)準(zhǔn)制定組織(Java Community Process, 簡稱JCP)的一部分. JCP負(fù)責(zé)處理和審批各種Java技術(shù)和技術(shù)規(guī)范,將新的Java特點系統(tǒng)化為應(yīng)用程序編程接口(API). 在android/dalvik/libcore/dom/src/test/java/org/w3c/domts下有很多java源文件，這意味著編譯Android之前需要先安裝JDK。 下載jdk 1.5的地址 http://java./products/archive/j2se/5.0_06/index.html 如果使用jdk1.6的版本將會出現(xiàn)如下的提示。 Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ -->============================================ Checking build tools versions... ************************************************************ You are attempting to build with the incorrect version of java.
