@stonier , thank you for replying. "rostopic info" shows: Usage: rostopic info/topic It doesn't show the image feed topic. |
You need to feed it with the image topic. I can't remember exactly what it is, but something like |
@stonier , /camera/rgb/image_raw any further steps i need to make, @stonier ? about my nexus exposing network interfaces.. nope. it is not. i switched to airplane mode and use solely on wifi. and there is not even an ip address on the rostopic list.. |
That looks like a

Doesn't matter if you are in wifi mode or 3g mode. Many modern phones expose both interfaces to java at the code level whether they are being used or not. My new phone does this, my old phone didn't. Anyway, first thing to check is to see what's coming up above. |
@stonier , can't be more grateful to have you replying. thank you so much. okay, i started up, "rosrun rviz rviz" and under Image.. Transport Hint, instead of "raw", i selected "compressed", however, i continued to run "rostopic info /camera/rgb/image_raw/compressed" and it gives me: Type: sensor_msgs/CompressedImage Publishers:

i can't seem to find the "/camera/rgb/image_raw/compressed" topic still. for step 4, i tried "rosrun rviz rviz". was just curious if i could find "/camera/rgb/image_raw/compressed" i also tried "rostopic find /camera/rgb/image_raw/compressed" but to no avail.

The singleTask launch mode now causes startActivityForResult to immediately cancel and return. Even though the master chooser would continue, any subsequent calls to finish would not return any meaningful activity result because it had already returned a cancelled result as it started. http://stackoverflow.com/questions/8960072/onactivityresult-with-launchmode-singletask This fixes #231. It may also have something to do with rosjava/android_remocons#61.

Any guides? Thanks.
