使用ant自动编译、打包生成apk文件

    上次使用命令行生成apk文件 《Android 命令行编译、打包生成apk文件》，学习命令行生成的目的是为了编写ant打下基础。

一、 ant环境

下载ant包，配置环境变量

二、ant编译Android项目

          <exec executable="aapt">
              <arg value="package" />
              <arg value="-m" />
              <arg value="-J" />
              <arg value="gen" />
              <arg value="-S" />
              <arg value="res" />
              <arg value="-M" />
              <arg value="AndroidManifest.xml" />
              <arg value="-I" />
              <arg value="${android-jar}" />
              <arg value="--auto-add-overlay" /> <!-- 覆盖资源 -->
          </exec>

          <javac  target="1.5" destdir="bin/classes" bootclasspath="${android-jar}">
              <src path="src" />
              <src path="gen" />
          </javac>

3. dx 命令，把class文件转换为.dex文件

转换为ant为：

          <exec executable="dx.bat" failonerror="true"> 
               <arg value="--dex" /> 
               <arg value="--output=${project-dir}\bin\classes.dex" /> 
            <arg path="${project-dir}\bin\classes" />
          </exec> 

转换为ant为：

          <exec executable="aapt">
               <arg value="package" />
               <arg value="-f" />
               <arg value="-M" />
               <arg value="AndroidManifest.xml" />
               <arg value="-S" />
               <arg value="res" />
               <arg value="-A" />
               <arg value="assets" />
               <arg value="-I" />
               <arg value="${android-jar}" />
               <arg value="-F" />
               <arg value="bin\resources.ap_" />
               <arg value="--auto-add-overlay" />
          </exec>

转换为ant为：

          <exec executable="apkbuilder.bat">
               <arg value="${project-dir}\bin\unsigned.apk" />
               <arg value="-u" />
               <arg value="-z" />
               <arg value="${project-dir}\bin\resources.ap_" />
               <arg value="-f" />
               <arg value="${project-dir}\bin\classes.dex" />
          </exec>

转换为ant为：

          <exec executable="jarsigner">
               <arg value="-keystore" />
               <arg value="${project-dir}\release.keystore" />
               <arg value="-storepass" />
               <arg value="antPassword" />
               <arg value="-keypass" />
               <arg value="antPassword" />
               <arg value="-signedjar" />
               <arg value="${project-dir}\bin\signed.apk" />
               <arg value="${project-dir}\bin\unsigned.apk" />
               <arg value="release" />
          </exec>

三、完整build.xml文件

<?xml version="1.0" encoding="utf-8"?>
<project default="main">

     <property name="android-jar" value="D:\android-sdk-windows\platforms\android-8\android.jar" />
     <property name="project-dir" value="D:\ProjectDemo" />

     <target name="init">
        <echo>start initing ... </echo>

        <mkdir dir="gen" />
        <delete>
            <fileset dir="gen"></fileset>
        </delete>
        
        <mkdir dir="bin/classes" />
        <delete>
            <fileset dir="bin/classes"></fileset>
        </delete>

        <echo>finish initing. </echo>
    </target>
    
    <target name="main" depends="init">
        <echo>generating R.java for project to dir gen (using aapt) ... </echo>
          <exec executable="aapt">
              <arg value="package" />
              <arg value="-m" />
              <arg value="-J" />
              <arg value="gen" />
              <arg value="-S" />
              <arg value="res" />
              <arg value="-M" />
              <arg value="AndroidManifest.xml" />
              <arg value="-I" />
              <arg value="${android-jar}" />
              <arg value="--auto-add-overlay" /> <!-- 覆盖资源 -->
          </exec>

          <javac  target="1.5" destdir="bin/classes" bootclasspath="${android-jar}">
              <src path="src" />
              <src path="gen" />
          </javac>
         
       
         
          <echo>packaging class files (include the third-party jars) to calsses.dex ... </echo>
          <exec executable="dx.bat" failonerror="true"> 
               <arg value="--dex" /> 
               <arg value="--output=${project-dir}\bin\classes.dex" /> 
            <arg path="${project-dir}\bin\classes" />
          </exec> 
         
         
          <echo>packaging resource (include res, assets, AndroidManifest.xml, etc.) to res.zip ... </echo>
          <exec executable="aapt">
               <arg value="package" />
               <arg value="-f" />
               <arg value="-M" />
               <arg value="AndroidManifest.xml" />
               <arg value="-S" />
               <arg value="res" />
               <arg value="-A" />
               <arg value="assets" />
               <arg value="-I" />
               <arg value="${android-jar}" />
               <arg value="-F" />
               <arg value="bin\resources.ap_" />
               <arg value="--auto-add-overlay" />
          </exec>
         
          <echo>building unsigned.apk ... </echo>
          <exec executable="apkbuilder.bat">
               <arg value="${project-dir}\bin\unsigned.apk" />
               <arg value="-u" />
               <arg value="-z" />
               <arg value="${project-dir}\bin\resources.ap_" />
               <arg value="-f" />
               <arg value="${project-dir}\bin\classes.dex" />
          </exec>
         
          <echo>signing the unsigned apk to final product apk ... </echo>
          <exec executable="jarsigner">

          </exec>
         
    </target>
