Android使用Ant自动编译签名打包详解
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>
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>
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.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>
5.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>
6.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> 7.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>

*在工程目录下建立一个build.bat批处理文件，内容为：
ant -buildfile build.xml
运行这个批处理文件即可。
注意：SDK的安装目录最后不要有中文和空格，否则会出现不必要的错误。如果你的安装路径包含Program Files（有空格），Ant方式打包会报错，没关系，不用重装，解决方法：配置SDk环境变量的时候把Program Files改为Progra~1即可。
