Well, my experience of debugging gst is trying simple pipeline first,
and then try complex case :)

IMHO, try following steps:
1. On android, try a fakesink pipeline, see whether buffers are
regularly generated by the encoder.
2. On android, try a udpsink pipeline, which will send data to an IP
of another machine:
[*] On that machine, to observe whether has data received:
gst-launch-1.0 -v udpsrc uri=udp://0.0.0.0:3057
caps='application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264,payload=(int)96,sprop-parameter-sets=(string)\"J0LgH41oBQBbpsgAAAMACAAAAwBAeKEVAA\\=\\=\\,KM4ESSA\\=\"'
! fakesink silent=false

It will print a log message on a received buffer. If no such log
messages, check your firewall settings first.

[*] On that machine, to playback encoded stream:
gst-launch-1.0 -v udpsrc uri=udp://0.0.0.0:3057
caps='application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264,payload=(int)96,sprop-parameter-sets=(string)\"J0LgH41oBQBbpsgAAAMACAAAAwBAeKEVAA\\=\\=\\,KM4ESSA\\=\"'
! rtpjitterbuffer latency=10 ! rtph264depay ! avdec_h264 ! videoscale
! autovideosink
