有關android工程的構建指令碼（build.xml）的學習

Android指令碼UIXML

學習【android-sdk-linux根目錄】/tools/ant/build.xml，覺得如下幾點很有用，記錄之

1）ant指令碼中屬性值是於前置定義優化的原則，即屬性發生重複定義時，前面定義的值不會被後面定義的覆蓋；

2）需要注意javac的交叉編譯引數（-bootclasspath <路徑>        覆蓋引導類檔案的位置），注意到它可能很容易理解在J2SE平臺下編譯android平臺的類檔案是怎麼做到的；

這裡有介紹該引數的文章：http://docs.oracle.com/javase/6/docs/technotes/tools/solaris/javac.html#options

3）可利用ant -debug的引數來研究android的build.xml（這個強烈推薦使用），可以檢視更多的日誌輸出，於便檢視target執行時的引數；

使用事列：ant -debug release

如下為部份log

 

-compile:

    [javac]     /home/luogw/dev-tool/sdk/android-sdk-linux/tools/helloworld/gen/com/luo/R.java

4）//TODO

 


注：目前我有個需求：想替換build.xml指令碼中的-bootclasspath的值

但它不是一個屬性值，不能通過前置定義的方式替換，暫時沒有想到解決方案
