Android include .jar in ant compilation

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 have a build.xml you have already edited (altered variables, custom imports, etc) and are a little nervous about running generic commands on it, you can also add:

<javac srcdir="libs"
     classpath="xyz.jar" />

to the build.xml file and it will work. It is the manual equivalent of the command

ant -lib lib debug

I just added lib to javac and it did the trick:

ant -lib lib debug

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).

If you're not familiar with how Ant works, it's easier to use Eclipse for your Android projects. Then you can add jars using a GUI. http://developer.android.com/guide/appendix/faq/commontasks.html#addexternallibrary

Also, based on your other question, this appears to be what you are attempting to do: http://developer.android.com/guide/developing/projects/projects-eclipse.html#SettingUpLibraryProject
