Microphone and speaker are chosen separately, so a Bluetooth headset can
play in media quality while the phone's own microphone listens, instead of
the headset dropping into its call profile. Devices are kept by type and
address: Android hands out new ids whenever one reconnects, and a line that
lost its device comes back to it when it returns.
The microphone preset (voice recognition by default, or the platform's
call processing, unprocessed, ...) and whether voices play as media or as
a call are Android's own settings. Changing either reopens the open
streams in place. Communication mode, and the headset's call link that a
Bluetooth microphone needs, are held only while a stream needs them, and
are set up before that stream opens.

android/ builds core and ts3j from the same sources as the desktop's
Maven build, so the app shares all of the client's logic:
- audio: Oboe streams behind AudioCapture/AudioPlayback, with a lock-free
ring between the real-time callback and the blocking Java side, and
libopus 1.5.2 built with the NDK behind OpusCodec. Speakers are mixed
onto one stream. Capture uses the VoiceRecognition preset, leaving
noise suppression and gain to the client's own processing.
- app: a plain connection screen to try the port out - connect,
microphone, mute, deafen, channel chat and a log - until the real UI.
Targets Android 13 and up (minSdk 33) on arm64 and x86_64.
