ant scripts to build apk file and load it in a emulator?

i am trying to create a build.xml script that cleans, builds and creates a apk file of a Junit android test project that i have created.

the steps i want to achieve in my build file is this:

clean

build

create apk file

Sign apk file

launch emulator

install apk file

run instrumentalTest

Save the tests into an HTML Junit Report

Anyone know how to achieve this? so far my build file looks like this:..

<!-- WARNING: Eclipse auto-generated file.
              Any modifications will be overwritten.
              To include a user specific buildfile here, simply

eclipse.ant.import?>
              as the first entry and export the buildfile again.

i can clean and build the project fine but dont know how to create the apk file, sign it, run the instrumentalTest and produce junit reports in html.

thanks in advance. this is the first time i have dived into this. i tried auto generating the build.xml using eclipse > project > export >ant build script and it doesnt add the apk building, running the instrumenatlTest and running the emulator stuff in it.
