how to generate apk using ant

Question

i want to know how can we generate apk file using ant script. i came to know that we can use "ant debug" command to do that.but when i am running this command it is returning error that " Target "debug" does not exist in the project". i am using ant1.7.0.is it the issue?i have tried given below code to generate apk.

 <target depends="build-subprojects,build-project" name="build">
    <jar destfile="bin/test.apk" basedir="bin/classes" >
  <manifest>
    <attribute name="Main-Class" value="test.Main" />
  </manifest>
</jar>
    </target>

but the generated apk is different from auto generated apk while build the app using eclipse.Please guide me.

Then you did not create your Android project properly, or you modified your build.xml file, or something else is broken.

As a test, I just ran the following command from my /tmp directory on Linux:

android create project --target android-17 --path Foo --package com.foo --activity Foo

I then changed into the Foo directory and ran ant debug . The app compiled, and in my bin/ directory is Foo-debug.apk .

If you are not getting this sort of result, delete your build.xml file and run android update project --path ... , where ... is the path to your project, to create a fresh build.xml file.
