RosCore on Android device results in "No such handler: system.multicall" #236

Closed r2DoesInc closed 6 years ago

r2DoesInc commented 9 years ago

When core is ran on the device - by selecting new public from the master chooser interface - publishing of messages fail.

To test, install and run example app found here - https://github.com/FutureHax/BrokenRos. Create new public through MasterChooser. Point another computer to to ros core instance created by the app. Attempt to publish a message.

See https://github.com/rosjava/rosjava_core/issues/84, ROSJava master does not indeed support multicall; it would be a nice feature to add.

This was fixed in https://github.com/rosjava/rosjava_core/pull/273.

For the record, I tested the ROS master running on Android compiling with this fix, and it worked fine.
