I am trying to build my android project using ant in command line mode. It works with eclipse and it used to work with ant until i installed the latest android sdk.
I run ant release -buildfile projectdir\build.xml. The compilation process is ok, and after aligning the apk, it fails at runtime with ClassDefNotFoundError acra.ACRA.
I have tried to remove any reference to acra from the project, but it will fail at runtime when trying to execute any code coming from a library jar.
My jars are in the libs folder at the root of the project. And I sort of understood this would cause ant to link them into the apk. But it doesn't.
When I used a previous version of the android sdk, I had a file named build.properties with an attribute referencing the jars folder external.libs.dir=libs. But now I can't make this to work any more, even if I use the new attributes names jar.libs.dir=libs and the new attributes file name ant.properties.
I read that ClassDefNotFoundError is caused because at compile time the librairies are found, but they are not linked into the apk, so they can't be found at runtime. How can I link the external jars in the apk please ?

There is no acra.ACRA class in ACRA, at least not in the current edition. It's org.acra.ACRA.

Yes, it does. Then ProGuard is removing them, unless you teach ProGuard not to.
