Remarks

Connects all user enabled and supported bluetooth profiles between the local and remote device. If no profiles are user enabled (e.g. first connection), we connect all supported profiles. If the device is not already connected, this will page the device before initiating profile connections. Connection is asynchronous and you should listen to each profile's broadcast intent ACTION_CONNECTION_STATE_CHANGED to verify whether connection was successful. For example, to verify a2dp is connected, you would listen for BluetoothA2dp.ACTION_CONNECTION_STATE_CHANGED

This method requires the calling app to have the Manifest.permission.BLUETOOTH_CONNECT permission. Additionally, an app must either have Manifest.permission.BLUETOOTH_PRIVILEGED permission or be associated with the Companion Device manager (see android.companion.CompanionDeviceManager.associate(AssociationRequest,android.companion.CompanionDeviceManager.Callback,Handler)). For apps targeting Build.VERSION_CODES.S or or higher, this requires the Manifest.permission.BLUETOOTH_CONNECT permission which can be gained with android.app.Activity.requestPermissions(String[],int).
