BluetoothManager

public final class BluetoothManager 

extends Object 

java.lang.Object
↳	android.bluetooth.BluetoothManager

High level manager used to obtain an instance of an 

BluetoothAdapter

 and to
conduct overall Bluetooth Management.

高级管理者用于获得BluetoothAdapter的实例并进行整体蓝牙管理

Use 

getSystemService(java.lang.String)

 with 

BLUETOOTH_SERVICE

 to
create an 

BluetoothManager

, then call 

getAdapter()

 to
obtain the

BluetoothAdapter

.

使用getSystemService(String)创建一个BluetoothManager BLUETOOTH_SERVICE,然后调用getAdapter()来获得theBluetoothAdapter。

Alternately, you can just call the static helper 

getDefaultAdapter()

.

或者,你可以调用静态辅助getDefaultAdapter()。

Added in API level 18

int getConnectionState (BluetoothDevice device,
int profile)

Get the current connection state of the profile to the remote device.
获取当前状态概要文件的远程设备的连接。

This is not specific to any application configuration but represents the connection state of the local Bluetooth adapter for certain profile. This can be used by applications like status bar which would just like
to know the state of Bluetooth.
