蓝牙

Android 4.3引入了BluetootheManager 来获取BlueAdapter，并加入了BLE（蓝牙低能耗）蓝牙加强版

private BluetoothAdapter mBluetooth;

    public void initBlueTooth(){
        if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.JELLY_BEAN_MR2){
            BluetoothManager bm = (BluetoothManager) getSystemService(BLUETOOTH_SERVICE);
            mBluetooth = bm.getAdapter();

        }else{
            mBluetooth = BluetoothAdapter.getDefaultAdapter();
        }
        if(mBluetooth==null){
            Toast.makeText( this,"不支持蓝牙", Toast.LENGTH_SHORT).show();
            finish();
        }
    }

启用蓝牙：enable()

关闭蓝牙：disable()

获取蓝牙状态：getState()
