/**
|
|
* Public API for controlling the Bluetooth Pbap Service. This includes Bluetooth Phone book Access
|
|
* profile. BluetoothPbap is a proxy object for controlling the Bluetooth Pbap Service via IPC.
|
|
*
|
|
* <p>Creating a BluetoothPbap object will create a binding with the BluetoothPbap service. Users of
|
|
* this object should call close() when they are finished with the BluetoothPbap, so that this proxy
|
|
* object can unbind from the service.
|
|
*
|
|
* <p>This BluetoothPbap object is not immediately bound to the BluetoothPbap service. Use the
|
|
* ServiceListener interface to obtain a notification when it is bound, this is especially important
|
|
* if you wish to immediately call methods on BluetoothPbap after construction.
|
|
*
|
|
* <p>To get an instance of the BluetoothPbap class, you can call {@link
|
|
* BluetoothAdapter#getProfileProxy(Context, ServiceListener, int)} with the final param being
|
|
* {@link BluetoothProfile#PBAP}. The ServiceListener should be able to get the instance of
|
|
* BluetoothPbap in {@link android.bluetooth.BluetoothProfile.ServiceListener#onServiceConnected}.
|
|
*
|
|
* <p>Android only supports one connected Bluetooth Pce at a time.
