[ros-users] [Discourse.ros.org] [Client Libraries/rosjava] Sending a Byte Array Message

[Ernesto Corbellini]

Hi Gabriel,
Can you paste the error message from logcat?
Also you can check [this example](https://github.com/rosjava/rosjava_bootstrap/blob/kinetic/message_generation/src/test/java/org/ros/internal/message/RawMessageSerializationTest.java#L244-L252) to compare.
