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

问题

I see above log message when initiating SIP call from Android app using Android SIP SDK. Here's the line which causes it:

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

I don't think there's anything wrong (at least related to the above message) in that line. But anyway, after that method is called, I see

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

And SIP call never gets established. Also, I don't receive any error messages/exceptions - nothing. Have any idea?

Thanks in advance.

Edited:

Btw, according to my investigation, "recursive attempt to load library" doesn't affect functionality. On majority of devices SIP calls work for me. But on Samsung Tab A (2016) I see exactly same behavior as described above.
