Explain RosTextView
I am working with the android_tutorial_pubsub package and have built an app that publishes to a node and subscribes to another. I also have two RosTextView widgets, which I want to display activity over my "publishing" rostopic and my "subscribing" rostopic. the tutorial has built-in functionality to display the publisher's messages on the RosTextView, but I cannot seem to get the subscriber messages to do the same. All the nodes and topics are set up correctly [per rxgraph], but I do not understand RosTextView enough to know how it gets its information or if subscriber should be pushing new messages to it.
Any help is appreciated.
