Android SIP - recursive attempt to load library "/system/lib/librtp_jni.so"

Question

I see the above log message when starting a SIP call from an Android application using the Android SIP SDK. Here is the line that calls this:

mSipManager.makeAudioCall(mSipProfileLocal, mSipProfilePeer, listener, 20);

I don't think that something is wrong on this line (at least related to the above post). But anyway, after calling this method, I see

recursive attempt to load library "/system/lib/librtp_jni.so"

And the SIP call is never set. Also, I don't get any error / exception messages - nothing. Any ideas?

Thanks in advance.

Btw, according to my research, a "recursive attempt to load a library" does not affect functionality. On most devices, SIP calls work for me. But on Samsung Tab A (2016), I see exactly the same behavior as described above.
