I'm searching for a simple way, so that my android application can send and receive messages from my Laptop via ROS Kinetic. Simple double or string variables are enough. I found lots of tutorials but they are not working for me or to complicated for me or not with ROS kinetic. I hope you guys can help me.

Best regards

Hi @splash99,

Take a look at There are already sample apps out there showing how to do a simple pubsub: I'd suggest you to compile that application and use it as a starting point for your purposes.

Hope it helps!

EDIT: Check this issue for a workaround to create an Android project. Note that the command line tool just creates a template for a new project, but nothing else that is very sophisticated. You can do the same editing an existing project instead of starting from scratch.

I lost the track on this count of tutorials.. Could you maybe help me? I just need one tutorial that I can walk through, but every tutorial I find, is deprecated at any point and I cant fix this.. I just want a really simple connection betwenn my android tablet and a ros master on a pc that can send and receive simple double values.

Just build pubsub tutorial:

In two steps:

That should build android_tutorial_pubsub apk for you. Install it to your Android device using adb and that should be it.

when i try to build it it says:

Deprecated Gradle features were used in this build, making it incompatible with Gradle 5.0. Use '--warning-mode all' to show the individual deprecation warnings. See

Is that a warning or an error? Look for an APK file inside your source directory, it should be there already.

ok, i started the apk now on my emulated android device. And I can connect to the Ros Master, which runs on the same Laptop as the emulator. But how can I now send and receive messages? Is there any explanation of the pubsub app?

That must be a local problem. Try an online search for that error; e.g:

Hi @jubeira,

thanks for your answer. When I start your tutorial it says after a few steps:

NOTE: Creating Android projects from the command line won't be supported with Build tools > 25.0.2. The tool supporting this command in Android's SDK has been officially deprecated, so to start a new project Android Studio has to be used.

Do you maybe have another Tutorial, that I can use?

Every Tutorial ends up in some tutorials for indigo like this:

It starts as tutorial for kinetic but the next site is indigo. Isnt there any tutorial which is only for kinetic?

@splash99 please note that the idea behind ROS answers is not a forum; please use comments to ask for clarifications or open a new question if necessary; the answers section should only contain answers. I'll edit my answer with a workaround for that.
