no element rtspsrc on Android

I have a simple console app that read from rtsp source and print a * for
every received buffer at the appsink. Here is the my pipeline "rtspsrc
location=rtsp://<ip> ! queue ! application/x-rtp,media=video ! rtph264depay
! h264parse ! video/x-h264, stream-format=byte-stream ! avdec_h264 !
videoconvert ! video/x-raw, format=I420 ! appsink name=sink"

it works as expected on linux. I cross-compiled the console app for android.
When trying to run the console app I am getting "no element rtspsrc" error
message. (I am using adb to run the app from the command line on the device)

here is my Android.mk

LOCAL_SRC_FILES:= hello.cpp gstCamera.cpp
LOCAL_SHARED_LIBRARIES := gstreamer_android

ifndef GSTREAMER_ROOT_ANDROID
$(error GSTREAMER_ROOT_ANDROID is not defined!)
