Ah yes I stumbled upon this too. The androidmedia plugin will not correctly initialize if you don’t include the Ahc callbacks in your Java code. I don’t understant how it could work on Android 7 though, since this happened to me on 7.0. Just add the following classes to your Java project:

GstAhcCallback.java
GstAhsCallback.java
GstAmcOnFrameAvailableListener.java

I can’t find them on my Linux system even though I installed gst-plugins-bad (there’s no gst-android package for Ubuntu, it seems?) but you can find them in git:
