1. build.xml

<?xml version="1.0" encoding="UTF-8"?>
<project name="project" default="help">
    <property file="local.properties" />
    <property file="ant.properties" />
    <loadproperties srcFile="project.properties" />
    <fail message="sdk.dir is missing. Make sure to generate local.properties using 'android update project' or to inject it through an env var" unless="sdk.dir"/>
    <import file="${sdk.dir}/tools/ant/build.xml" />
</project>

2. 把proguard.jar放到ant/lib目录

3. default.properties

# Project target.
target=android-8
sdk.dir=/home/bonjour/dev/androidsdk
