rostango unsupported method at runtime

edit

Following the instructions here: https://github.com/ologic/Tango/wiki/ROSTango-Instructions

I am able to successfully catkin_make and open the project in tango-studio (0.6.1).

When I try to run any of the apps, it sees the tango tablet, Target device: google-yellowstone.... I select it and then the process fails with: Unsupported method: AndroidArtifact.getOutputFile(). The version of Gradle you connect to does not support that method

I have the same issue with the samples built from here: https://github.com/ologic/Tango/wiki/Getting-Started-with-Tango-and-ROS and submitted a ros.answers question for that as well: http://answers.ros.org/question/199283/ros-tango-samples-dont-run/

The gradle build messages show that "Tooling API is using target Gradle version 1.12" which could go with plugin version 0.11 but I don't know how to check for the Android Gradle Plugin version (it should be 0.11 to work with studio version 0.6.1) and I am pretty sure this problem is due to using the wrong Plugin version.

I think that all I have to do is edit the build.gradle file to select plugin version 0.11, but I don't know how to do that. I tried editing build.gradle , changing

classpath group: 'org.ros.rosjava_bootstrap', name: 'gradle_plugins', version: '0.1.22'

to a variety of different versions (0.11 (not found), 0.11+ (not found), 0.1+ (found, but generates the same error)).

Here is the relevant section of build.gradle:

task wrapper(type: Wrapper) {
    gradleVersion = '1.12'
}

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: '0.1.22'
        // compile 'org.ros.tf2:tf2_ros:0.0.0-SNAPSHOT'
    }
}
