Problem when transmitting camera from android to Wowza

Question

I am trying to transmit the Android camera image via rtsp to Wowza, however without success. It does not return any error, but also in the local Wowza does not show any traffic. I have the local Wowza for testing in http://localhost:8088/ I am using the Libstreaming library to send the rtsp stream.
