Android include .jar in ant compilation

Question

I try to include in my application compilation a .jar compiled.

I use ant to compile my Android application.

When I add this task to build.xml :

 <javac srcdir="${src}"
     classpath="xyz.jar" />

compilation failed on android package importation :

[javac] Compiling 1 source file
[javac] C:\HelloWorld\src\com\example\hellowolrd\HelloWorld.java:3: package android.app does not exist
[javac] import android.app.Activity;
[javac]                   ^

Whereas when my task was not in build.xml, compilation succeeded.

If you're using the standard ant script from android create project then you should be able to dump any jars in a libs directory and have them included automatically (documentation).
