however if i move my libraries to /libs i can start the applications, but with the libraries in /libs javadoc and javasources stops working, while if they are not in /libs javadoc and javasource works, so I don't understand why.

Answer 1

Have a look at Xavier Ducrohet's answers here. But basically, with adt17 you cannot attach Javadoc to your dependencies.

Answer 2

For non library projects:

As mentioned in the original question comment 8 in this android issue fixes the build, runtime and javadoc issues, albeit by way of a kludge.

Unfortunately Ant builds are broken. To fix Ant builds which use Proguard, move jars to lib as described in comment 8 and to ant.properties add:

jar.libs.dir=lib

and to proguard.cfg add:

-injars lib

The second addition is necessary to fix runtime crashes.

I've not tested this for projects that use instrumentation or emma tasks, but it seems OK for non-library projects where you want both an Eclipse and an Ant build.
