According to this page my Apple device supports AVRCP 1.4.
According to this one my Android 8.0 device also supports AVRCP 1.4.
However according to this Android Bluetooth API only allows me access to Headset, A2DP and Health Device profiles, so why the second link is saying that AVRCP is supported? Is it supported by low level API and there is no high level API?
My goal is to control media being played on Apple device from Android device without using MFI program. I thought that AVRCP will be best for this purpose but currently I'm struggling with writing even some very basic app which would just do play / pause.
I've tried listenUsingInsecureRfcommWithServiceRecord with AVRCP UUID
("0000110E-0000-1000-8000-00805F9B34FB") using BluetoothAdapter. I've tried createInsecureRfcommSocketToServiceRecord with this UUID using BluetoothDevice and I've also tried some hidden API like that:
boolean result = mBluetoothAdapter.getProfileProxy(this, listener, /*BluetoothProfile.AVRCP_CONTROLLER*/ 12);
result was true but nothing happened or I didn't know what to do next.
Do you have any tips? Maybe there is some problem which I'm unaware of?
