Android: How to pass version info during ant command line build?

Question

When I build an Android project in command line using Ant, I would like to update the android:versionCode and android:versionName in AndroidManifest.xml file. Are there someways I can inject version number using a property file?

You can set version info in several ways,

1. Passing as command line parameters
2. Using a property file.

To pass as command line parameters,

 <target name="set-version-using-commandline-args">
    <!-- Load properties from "version.properties" file -->     
    <replaceregexp file="AndroidManifest.xml" match="android:versionCode(.*)" 
        replace='android:versionCode="${Version.Code}"'/>
    <replaceregexp file="AndroidManifest.xml" match="android:versionName(.*)" 
        replace='android:versionName="${Version.Name}"'/>       
</target>

Then run the ant build like this,

ant -DVersion.Code=100 -DVersion.Name=5.0.0.1201011 debug 

If you want to pass the version info using a property file, use this target,

 <target name="set-version-using-file">
    <!-- Load properties from "version.properties" file -->             
    <property file="version.properties" />

    <replaceregexp file="AndroidManifest.xml" match="android:versionCode(.*)"
        replace='android:versionCode="${Version.Code}"'/>
    <replaceregexp file="AndroidManifest.xml" match="android:versionName(.*)"
        replace='android:versionName="${Version.Name}"'/>       
</target>
