这篇文章对android打包过程的每个步骤做了详细的解释,这里我给一个Maven简单版本作为概括

第一步, aapt,如果pom依赖中有apklib,将会先解压,与原文件一起产生aidl r等文件。
第二步, aidl,javac,编译, 和传统maven编译一样, 需要解决依赖, 包冲突等还有scope。
第三步, proguard,混淆,发布包需要,会把所有依赖的jar包放一起处理, 形成混淆后的单一jar包
第四步, Dex, 混淆后的jar包, 处理成delvik认识的classes.dex。
第五步, apkbuilder,打APK,将把所有资源文件, 和dex, 打包成为apk。
​第六步, 有maven插件支持,将替换相应的资源文件和配置项, 最后再次调用aapt打包。
最后  , jarsigner,ziplign就是类似签名,对齐等操作不表

​渠道包的关键是在第六步, 注意是一次编译class,一次混淆。便可打出n多个渠道包。

​每一步都是过程明确,产出目标明确,可以使用maven。

如下引用原文:


1.Android程序编译、打包、签名、发布的三种方式:
方式一:命令行手动编译打包
方式二:使用ant自动编译打包
方式三:使用eclipse+ADT编译打包

2.Android编译、打包的步骤:
2.1第一步 生成R.java类文件:
Eclipse中会自动生成R.java,ant和命令行使用android SDK提供的aapt.ext程序生成R.java。

2.2第二步 将.aidl文件生成.java类文件:
Eclipse中自动生成,ant和命令行使用android SDK提供的aidl.exe生成.java文件。

2.3第三步 编译.java类文件生成class文件:
Eclipse中自动生成,ant和命令行使用jdk的javac编译java类文件生成class文件。

2.4第四步 将class文件打包生成classes.dex文件:
Eclipse中自动生成,ant和命令行使用android SDK提供的dx.bat命令行脚本生成classes.dex文件。

2.5第五步 打包资源文件(包括res、assets、androidmanifest.xml等):
Eclipse中自动生成,ant和命令行使用Android SDK提供的aapt.exe生成资源包文件。

2.6第六步 生成未签名的apk安装文件:
Eclipse中自动生成debug签名文件存放在bin目录中,ant和命令行使用android SDK提供的apkbuilder.bat命令脚本生成未签名的apk安装文件。

2.7第七步 对未签名的apk进行签名生成签名后的android文件:
Eclipse中使用Android Tools进行签名,ant和命令行使用jdk的jarsigner对未签名的包进行apk签名。

4.ant自动打包android程序详解
4.1生成R.java类文件:
  
 <!-- Generate the R.java file for this project's resources. --> 
    <target name="resource-src" depends="copy"> 
        <echo>Generating R.java / Manifest.java from the resources...</echo> 
        <exec executable="${aapt}" failonerror="true"> 
<arg value="package" /> 
<arg value="-m" /> 
<arg value="-J" /> 
<arg value="${outdir-gen}" /> 
<arg value="-M" /> 
<arg value="AndroidManifest.xml" /> 
<arg value="-S" /> 
<arg value="${resource-dir}" /> 
<arg value="-I" /> 
<arg value="${android-jar}" /> 
</exec> 
    </target> 


4.2将.aidl文件生成.java类文件:
 
  <!-- Generate java classes from .aidl files. --> 
    <target name="aidl" depends="copy"> 
        <echo>Compiling aidl files into Java classes...</echo> 
        <apply executable="${aidl}" failonerror="true"> 
            <arg value="-p${android-framework}" /> 
            <arg value="-I${srcdir}" /> 
            <fileset dir="${srcdir}"> 
                <include name="**/*.aidl"/> 
            </fileset> 
        </apply> 
</target> 


4.3编译.java类文件生成class文件:
  
 <!-- Compile this project's .java files into .class files. --> 
    <target name="compile" depends="copy, resource-src, aidl"> 
        <javac encoding="GB18030" target="1.5" debug="true" extdirs="" 
                srcdir="." 
                destdir="${outdir-classes}" 
                bootclasspath="${android-jar}"> 
            <classpath> 
                <fileset dir="${external-libs}" includes="*.jar"/> 
            </classpath> 
         </javac> 
    </target> 

  
4.4第四步 将class文件打包生成classes.dex文件:
  
 <!-- Convert this project's .class files into .dex files. --> 
    <target name="dex" depends="compile"> 
        <echo>Converting compiled files and external libraries into ${outdir}/${dex-file}...</echo> 
        <apply executable="${dx}" failonerror="true" parallel="true"> 
            <arg value="--dex" /> 
            <arg value="--output=${intermediate-dex-ospath}" /> 
            <arg path="${outdir-obfuscate-classes-ospath}" /> 
            <fileset dir="${external-libs}" includes="*.jar"/> 
        </apply> 
    </target> 

4.5第五步 打包资源文件(包括res、assets、androidmanifest.xml等):
 
 <!-- Put the project's resources into the output package file. --> 
    <target name="package-res-and-assets"> 
        <echo>Packaging resources and assets...</echo> 
        <exec executable="${aapt}" failonerror="true"> 
            <arg value="package" /> 
            <arg value="-f" /> 
            <arg value="-M" /> 
            <arg value="AndroidManifest.xml" /> 
            <arg value="-S" /> 
            <arg value="${resource-dir}" /> 
            <arg value="-A" /> 
            <arg value="${asset-dir}" /> 
            <arg value="-I" /> 
            <arg value="${android-jar}" /> 
            <arg value="-F" /> 
            <arg value="${resources-package}" /> 
        </exec> 
    </target> 

4.6第六步 生成未签名的apk安装文件:
  <target name="package" depends="dex, package-res"> 
        <echo>Packaging ${out-unsigned-package} for release...</echo> 
        <exec executable="${apk-builder}" failonerror="true"> 
            <arg value="${out-unsigned-package-ospath}" /> 
            <arg value="-u" /> 
            <arg value="-z" /> 
            <arg value="${resources-package-ospath}" /> 
            <arg value="-f" /> 
            <arg value="${intermediate-dex-ospath}" /> 
            <arg value="-rf" /> 
            <arg value="${srcdir-ospath}" /> 
            <arg value="-rj" /> 
            <arg value="${external-libs-ospath}" /> 
        </exec> 
        <echo>It will need to be signed with jarsigner before being published.</echo> 
    </target> 

   
4.7第七步 对未签名的apk进行签名生成签名后的android文件:
<target name="jarsigner" depends="package">
<echo>Packaging ${out-unsigned-package} for release...</echo> 
<exec executable="${jarsigner}" failonerror="true"> 
<arg value="-verbose" /> 
<arg value="-storepass" /> 
<arg value="byread002" /> 
<arg value="-keypass" /> 
<arg value="byread002" /> 
<arg value="-keystore" /> 
<arg value="bbyread.keystore" /> 
<arg value="-signedjar" /> 
<arg value="${out-signed-package-ospath}" /> 
<arg value="${out-unsigned-package-ospath}" /> 
<arg value="byread" /> 
</exec> 
</target>
