Improve Audio Quality by Switching to AAudio API in 3CX Android App Beta

[nb]

3CX Android App Beta now adds Google’s AAudio API as an added alternative to the commonly used OpenSL (Sound Library). The 3CX App has so far used OpenSL which is still functional and widely used.

That's a nice addition, I'll see whether that resolves the echo problems we've been having with some phones!

Problems:

• Tapping on call quality indicator shows all blank screens for Statistics, Input and Output
• Switching to audio subsystem "Automatic" causes one-way audio (on the Android phone -> other phone). I can't hear anything on the Android phone but the other person can hear me. Switching back to OpenSL makes sound in both directions work again.
• Screen doesn't wake up when receiving a call. Ring tone works.

And one positive thing I noticed: The latest 3CX "release" app keeps ringing when I pick up a call on my PC and not on the Android phone. I have to turn on the phone so it stops.
This seems fixed with the 3CX 16.2.0.81 Beta.
