Question

I am using Ant to build my Android project. The Android project is checked into Tortoise SVN. Now when I create a build I want the apk files to ideally get generated into different folders on windows stating the version number of the build. For example on first build (ant release) I would like to have the folder bin/1.0/sample.apk and for the next bin/2.0/sample.apk so I cant maintain different versions.And ideally the version numbers should be version number of the manifest(right?). How can this be done ?

You can have a custom_rules.xml file in your project that contains the statements for copying your apk to the required folder in a -post-build target. You can use the copy task to take care of it.

To retrieve the version information from the manifest, follow this answer on SO.

A sample of the custom_rules.xml would be:

<?xml version="1.0" encoding="UTF-8"?>
<project name="custom_rules">
    <xmlproperty file="AndroidManifest.xml" prefix="mymanifest" collapseAttributes="true"/>
    <property name="build.dir" value="bin/${mymanifest.manifest.android:versionName}/" />   
    <target name="-post-build">
        <echo>Version is ${mymanifest.manifest.android:versionName}</echo>
        <copy toDir="${build.dir}" >
            <fileset file="${out.final.file}" />
        </copy>
    </target>
</project>

Note: Currently, the apk is copied to a sub-folder of ‘bin’ folder. You would have to think of another directory as the ‘bin’ folder will be deleted on every clean operation.
