Dynamically linking plugin in GStreamer on Android

[Bruce Tsai]

Thanks Sebastian.

So my plan is putting my plugin in the app and build the plugin along with
the app.
And let my plugin link to libgstreamer_android.so.
In this case, whether do I need to set "GST_PLUGIN_PATH" to let GStreamer
scan my app's shared lib?
