I think it would be nice to create a simple view to visualize the vio data in the app.

After following the step install the ROS Java Android workspace in @https://github.com/ologic/Tango/wiki/Getting-Started-with-Tango-and-ROS , I encountered a build failed problem.

:android_tutorial_hokuyo:processReleaseResources FAILED

FAILURE: Build failed with an exception.

* What went wrong:

For the trace, I found a list of errors retrieving parent for item ...

Here are several errors:

I am using the latest Android Studio and Kinetic Ros. Is this the problem??

Is ROS Indigo supported by Tango?

This should be reflected in the docs

Hi everyone,

I sucessfully compiled everything, and tango publishes to the /tango_pose topic. However, when I do rostopic echo, the position and orientation data are all 0, only the time stamp is changing. Also, I checked {}Project Tango in Settings, none of the ologic app (TangoVio,TangoDepthImage) has permission on Motion Tracking (I don't think any of them ask me for permission, after I hit the connect button I only see "Hello World, TangoVio"). Can anybody explain why?

Hi everyone,

First a big thank you for putting out your repository for free and also for documenting everything.

I ran into a little bit of an issue with my Tango Tablet (running on 4.4.2): I can't find the launch file for it (tango_vio_ys.launch) as described in the wiki. I tried with the regular one, however, I am getting 0s for all elements in the position and orientation messages, so the vio app doesn't work. Could somebody provide some help for getting this set up? The depth map app works properly, by the way.

Thanks a lot!
Marc

With this PR the mainline MAVLink repo will have gained the ability to generate Java messages:
mavlink/mavlink#228

We will need to update to this message set soon, as this is the standardised, long-term stable variant.

Project is using an unsupported version of the Android Gradle plug-in (0.11.2)

I couldn't figure out how to update that dep.

Given the short battery life, we will want to soon work out how to power the device via a DC-DC converter. What is the peak current rating we need to sustain on this?

Because of an incompatibility between studio 0.6.1 and 0.9 it is not possible to use the projects from this repo with a recent android studio version. I am happy helping with this.

Currently the app stops if the screensaver enables. This may have adverse consequences during flight, as suddenly position information is lost. Could we please allow the app to continue to run even if the screen is locked?

Seems like the same issue as issue #2 but this time with the latest version of Android.

I have the latest version of repo and just started.
First I get the error

the project is using an unsupported version of the android gradle plug-in (0.12.2). the recommended version is 1.0.0

So I changed the build.gradle to

 classpath group: 'org.ros.rosjava_bootstrap', name: 'gradle_plugins', version: '1.0.0'

Now I get this error

Could not resolve org.ros.rosjava_bootstrap:gradle_plugins:1.0.0.
Required by:

:rostango:unspecified

What would you recommend? Downgrading Android?

this is more of a medium term thing, but it will be soon relevant to keep an eye on battery life / status remotely, as a sudden loss of position will have adverse effects on the flight 8).

Right now the app requires Wifi (and maybe a valid IP address). I'm not always having this available even in the early testing now @bblodget any chance of quickly changing this?

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:

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)
