For the env, see QAndroidJniEnvironment() (* operator). And for the
jobject I believe this is the activity, see androidActivity(). Getting
the activity is asynchronous, so that new API is still very
inconvenient.

In a internal project (non-public sorry), I've rewritten this init
function in plane C, using GResource instead of Java equivalent, and
passing the path manually (instead of using JNI to figure-it-out).
Imho, I believe we need gst_static_init() somewhere that would deal
with the non-Android bits in a friendlier way. gst_android_init() could
then we simplified a lot, and only deal with the Android specifics
(which are not needed when running Qt for Android).
