Android ant 编译 apk文件名含版本号

项目中总会遇到使用ant编译的情况，eclipse的项目，使用jenkins 做CI的时候就要使用，编译完成后的包名一般是下面这样的格式
项目名-[是否签名]-[是否压缩]-编译模式.apk
然后编译出来的apk包文件名缺少版本，不方便识别。
用下面的build.xml即可解决这个没有版本号的问题

<?xml version="1.0" encoding="UTF-8"?><project xmlns:sonar="antlib:org.sonar.ant"    name="HospitalAndroid"    default="help" >    <property file="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" />    <xmlproperty        collapseAttributes="true"        file="AndroidManifest.xml"        prefix="themanifest" />    <property        name="out.final.file"        location="${ant.project.name}-${themanifest.manifest.android:versionName}-release.apk" />    <!--         if sdk.dir was not set from one of the property file, then         get it from the ANDROID_HOME env var.         This must be done before we load project.properties since         the proguard config can use sdk.dir    -->    <property environment="env" />    <condition        property="sdk.dir"        value="${env.ANDROID_HOME}" >        <isset property="env.ANDROID_HOME" />    </condition>    <!--         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 &apos;android update project&apos; or to inject it through the ANDROID_HOME environment variable."        unless="sdk.dir" />    <!--        Import per project custom build rules if present at the root of the project.        This is the place to put custom intermediary targets such as:            -pre-build            -pre-compile            -post-compile (This is typically used for code obfuscation.                           Compiled code location: ${out.classes.absolute.dir}                           If this is not done in place, override ${out.dex.input.absolute.dir})            -post-package            -post-build            -pre-clean    -->    <import        file="custom_rules.xml"        optional="true" />    <!--         Import the actual build file.         To customize existing targets, there are two options:         - Customize only one target:             - copy/paste the target into this file, *before* the               <import> task.             - customize it to your needs.         - Customize the whole content of build.xml             - copy/paste the content of the rules files (minus the top node)               into this file, replacing the <import> task.             - customize to your needs.         ***********************         ****** IMPORTANT ******         ***********************         In all cases you must update the value of version-tag below to read 'custom' instead of an integer,         in order to avoid having your file be overridden by tools such as "android update project"    -->    <!-- version-tag: 1 -->    <import file="${sdk.dir}/tools/ant/build.xml" /></project>

关键代码就是下面这段

<xmlproperty    collapseAttributes="true"    file="AndroidManifest.xml"    prefix="themanifest" /><property    name="out.final.file"    location="${ant.project.name}-${themanifest.manifest.android:versionName}-release.apk" />

其实很简单，就是在打包之前，AndroidManifest中的versionName读取出来，加在out.final.file属性里
