Imposible to do catkin_make (UNEXPECTED TOP-LEVEL EXCEPTION:)

[MatthieuCotton]

follow this tutorial https://github.com/ologic/Tango/wiki/... to import the project. When I try to make the project with catkin_make, I have this error:

UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexException: Multiple dex files define Lorg/ros/android/MessageCallable;

I try many issue to try to fix it, with no result. My distro is Hydro and I use Android Studio 0.6.1 like the tutorial say.

the project's build.gradle :

task wrapper(type: Wrapper) {
gradleVersion = '1.11'
}

buildscript {
def rosMavenPath = "$System.env.ROS_MAVEN_PATH".split(':').collect { 'file://' + it }
def rosMavenRepository = "$System.env.ROS_MAVEN_REPOSITORY"
repositories {
rosMavenPath.each { p ->
maven {
url p
}
}
mavenLocal()
maven {
url rosMavenRepository
}
}
dependencies {
classpath group: 'org.ros.rosjava_bootstrap', name: 'gradle_plugins', version: '[0.1,0.2)'
}
}

apply plugin: 'catkin'

allprojects {
group 'com.github.rosjava.android_extras'
version = project.catkin.pkg.version
}

subprojects {
apply plugin: 'ros-android'
}
and subproject's build.gradle which poses problem:

dependencies {
compile 'org.ros.android_core:android_gingerbread_mr1:[0.1,)'
compile 'org.ros.android_core:android_acm_serial:[0.1,)'
compile 'com.github.rosjava.rosjava_extras:hokuyo:[0.1,)'
}

apply plugin: 'android'

android {
packagingOptions {
/* rosjava/android_core#194 */
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/NOTICE.txt'
}
compileSdkVersion 13

}
Please, anybody can help me ? (Sorry for my poor english)
