Android how to create apk file using ant script

Question

anybody tell me, building apk using ant script

Answer 1

Check the android developers documentation in the Building and Running from the Command Line topic. Assumed you created your project with the android tool it should be:

ant release

The documentation also describes the "eclipse with ADT" way

If you first set up the project with eclipse than try to create a new temp project with the android create project command line command and take the build.xml (and build.properties + local.properties) from the new project for your existing one.
