Problems with Bluecove+Android

[Mariajo]

Hi all.

I'm trying to develop an Android app (client that would connect with a
file server application via Bluetooth) using Java and Bluecove for my
final project. I could develop another J2SE client using Bluecove
without any problems, but the Android part is being a bit messy.

I'm using Mac OS X (10.6.8), Eclipse SDK (3.7.2), and HTC Desire A8181
(Android v2.2).



Following Mina's instructions in these emails...

(1) http://groups.google.com/group/bluecove-developers/msg/847f714034b34126
(2) http://comments.gmane.org/gmane.comp.java.bluecove.devel/32

... I downloaded "bluecove-2.1.1-SNAPSHOT.jar" and "bluecove-gpl-2.1.1-
SNAPSHOT.jar" from here:

(3) http://snapshot.bluecove.org/distribution/download/2.1.1-SNAPSHOT/2.1.1-SNAPSHOT.63/

I extracted the "gpl.jar" content, deleted the libbluecove.so in it,
and built the jar file again. Then added the two .jar files to my
Eclipse project (Build path -> Configure build path -> Libraries ->
Add externarl jars), and manually created libs\armeabi folders and
copied the "libbluecove.so" file attached in (1) there.

The project compiled without problems. I used the telephone for
debugging, but the app crashed when calling the first class
(CodigoComm) that uses Bluecove. Here is the LogCat output:

As far as I understand, it seems like the telephone doesn't know
anything about the Bluecove classes. Should the "libbluecove.so"
appear in the /system/lib folder of the HTC? It doesn't. Am I
including the .jar and .so files properly?



I've also tried downloading Bluecove's source code from here...
(4) http://code.google.com/p/bluecove/source/browse/trunk/?r=3062
... and building the whole project myself using Maven 3.0.3, but "mvn
package" gets this error log:

Anyway, as "bluecove-2.1.1-SNAPSHOT.jar" and "bluecove-android2-2.1.1-
SNAPSHOT.jar" are generated, I replaced the other .jar files with
these ones, following the instructions here:
(5) http://code.google.com/p/bluecove/source/browse/trunk/bluecove-android2/src/site/apt/index.apt

Same result. The app crashes when calling CodigoComm.


Do you have any idea of what may be happening?

Thanks in advance (and sorry for the long email)

This crash doesn't look like to be related to bluecove.
