Ant 命令行编译Android项目

首先把android sdk下的tools目录加到系统path环境变量里, 要么就得直接指定android.bat的绝对路径

对于一个新项目, 可以用这个命令创建需要的ant编译环境(可以看到android项目默认的文件结构)

android create project -k com.foo -a Test1 -t android- -p d:\temp

如果是已经存在的项目, 对主项目和子项目都运行

项目目录> android update project -s -p . -t android-

-s 是因为带子项目

-t 是指定目标版本, 版本不对会导致编译失败

其中

build.xml 是ant任务文件, 基本不用修改

custom_rules.xml 对于需要自行配置的编译任务, 写到这个文件里, 会被build.xml加载

ant.properties ant运行中涉及的变量写到这里

local.properties 里面设定了sdk.dir的路径, 不用修改

project.properties 设定了编译目标和项目类型, 如果有子项目的话, 还有子项目的路径, 不用修改

然后执行下面的命令就进行编译了

项目目录>D:\apache-ant-1.8.\bin\ant.bat clean

项目目录>D:\apache-ant-1.8.\bin\ant.bat release

根据中途报的错, 再做调整

如果子项目编译出错, 可以分别在子项目目录下运行ant clean 和 ant release, 直到排除错误

在生成的apk中使用版本号文件名, 而不是用默认的 xxx-release.apk

http://jeffreysambells.com/2013/02/14/build-your-android-apk-with-the-manifest-version-number

    <target name="-set-release-mode"

        depends="rename-release-with-version-number,android_rules.-set-release-mode">

        <echo message="target: ${build.target}"></echo>

    </target>

    <target name="rename-release-with-version-number">

        <xmlproperty file="AndroidManifest.xml" prefix="themanifest" collapseAttributes="true"/>

        <!--  see ${sdk.dir}/tools/ant/build.xml -set-release-mode -->

        <property name="out.packaged.file"

            location="${out.absolute.dir}/${ant.project.name}-${themanifest.manifest.android:versionName}-release-unsigned.apk" />

        <property name="out.final.file"

            location="${out.absolute.dir}/${ant.project.name}-${themanifest.manifest.android:versionName}-release.apk" />

    </target>

The -set-release-mode target overrides the same target in ${sdk.dir}/tools/ant/build.xml where the out.final.file file name is originally defined. To add the version number, I override -set-release-mode by calling my rename-release-with-version-number target in the dependencies and then calling the original android_rules.-set-release-mode to finish any other setup there.

The rename-release-with-version-number target simply reads in the manifest and adds the version number to both out.final.file and out.packaged.file.

Now the build APK is ProjectName-version-release.apk and it’s automatically used by the rest of the ant build process without clumsy file renaming.
