[ant]經過Android命令自動編譯出build.xml文件

用途: 作自動集成編譯環境.

環境搭配我就不說了(SDK/環境變量等).
進入cmd界面.
進入項目目錄.


輸入: android.bat list target  來查詢咱們現有的版本list有哪些.



記住這個ID號碼,下的代碼面會用到.
輸入: android update project -n ButtonDemo -t 1 -p E:\workspace\android\ButtonDemo

-n 對應的是項目名稱
-t 就是咱們以前查詢的SDK版本對應的ID,你們根據本身的項目版本作出選擇便可,我這個是android-8 因此用ID 1 .
-p就是生成的路徑
成功後顯示:


好了如下是生成的build.xml代碼段:

<?xml version="1.0" encoding="UTF-8"?>

<project name="ButtonDemo" default="help">

 

    <!-- The local.properties file is created and updated by the 'android' tool.

         It contains the path to the SDK. It should *NOT* be checked into

         Version Control Systems. -->

    <loadproperties srcFile="local.properties" />

 

    <!-- The ant.properties file can be created by you. It is only edited by the

         'android' tool to add properties to it.

         This is the place to change some Ant specific build properties.

         Here are some properties you may want to change/update:

 

         source.dir

             The name of the source directory. Default is 'src'.

         out.dir

             The name of the output directory. Default is 'bin'.

 

         For other overridable properties, look at the beginning of the rules

         files in the SDK, at tools/ant/build.xml

 

         Properties related to the SDK location or the project target should

         be updated using the 'android' tool with the 'update' action.

 

         This file is an integral part of the build system for your

         application and should be checked into Version Control Systems.

 

         -->

    <property file="ant.properties" />

 

    <!-- The project.properties file is created and updated by the 'android'

         tool, as well as ADT.

 

         This contains project specific properties such as project target, and library

         dependencies. Lower level build properties are stored in ant.properties

         (or in .classpath for Eclipse projects).

 

         This file is an integral part of the build system for your

         application and should be checked into Version Control Systems. -->

    <loadproperties srcFile="project.properties" />

 

    <!-- quick check on sdk.dir -->

    <fail

            message="sdk.dir is missing. Make sure to generate local.properties using 'android update project'"

            unless="sdk.dir"

    />

 

 

<!-- extension targets. Uncomment the ones where you want to do custom work

     in between standard targets -->

<!--

    <target name="-pre-build">

    </target>

    <target name="-pre-compile">

    </target>

 

    /* This is typically used for code obfuscation.

       Compiled code location: ${out.classes.absolute.dir}

       If this is not done in place, override ${out.dex.input.absolute.dir} */

    <target name="-post-compile">

    </target>

-->

 

    <!-- Import the actual build file.

 

         To customize existing targets, there are two options:

         - Customize only one target:

             - copy/paste the target into this file, *before* the

               <import> task.

             - customize it to your needs.

         - Customize the whole content of build.xml

             - copy/paste the content of the rules files (minus the top node)

               into this file, replacing the <import> task.

             - customize to your needs.

 

         ***********************

         ****** IMPORTANT ******

         ***********************

         In all cases you must update the value of version-tag below to read 'custom' instead of an integer,

         in order to avoid having your file be overridden by tools such as "android update project"

    -->

    <!-- version-tag: 1 -->

    <import file="${sdk.dir}/tools/ant/build.xml" />

</project>
