  - clearCallback
```
public void clearCallback()
```
    Remove all callbacks. (Japanese) コールバックを全て削除します。
  - addObserver
```
public void addObserver(IBarcodeReaderObserver observer)
```
    Add a observer. Events (connection completed, connection failed, disconnection, receive data) that occurred in the communication with the remote device are posted to all observers who manage it. Observers that have already been added are not added.
    
    Parameters:
    
    observer - observer for adding (Japanese) オブサーバを追加します。リモートデバイスとの通信で発生したイベント（接続完了、接続失敗、切断、データ受信）は、管理している全てのオブザーバに対して通知されます。すでに追加されているオブザーバは新たに追加されません。
    
    observer - 追加するオブサーバ。
  - removeObserver
```
public void removeObserver(IBarcodeReaderObserver observer)
```
    Remove a observer.
    
    Parameters:
    
    observer - observer for removing. (Japanese) オブサーバを削除します。
    
    observer - 削除するオブザーバ。
  - getCharSet

public static java.nio.charset.Charset getCharSet()
```
    get the character code.
    
    Returns:
    
    Current character code. (Japanese) 文字コードを取得します。
  - setCharSet
```
public static void setCharSet(java.lang.String strCharset)
```
    set the character code.
    
    Parameters:
    
    strCharset - character code for setting. (Japanese) 受信データの文字コードを設定します。
    
    strCharset - 設定する文字コード。
  - getConnectedDevice
```
public android.hardware.usb.UsbDevice getConnectedDevice()
```
    Gets the connected device.
    
    Returns:
    
    connected device. (null when disconnected) (Japanese) 接続中のデバイスを取得します。
  - onReceive
```
public void onReceive(android.content.Context context,
                      android.content.Intent intent)
```
    Intent receive processing. (Japanese) インテントの受信処理
    
    Specified by:
    
    onReceive in class android.content.BroadcastReceiver
  - run
```
public void run()
```
    リクエストの取得
    
    Specified by:
    
    run in interface java.lang.Runnable
  - getState
```
public BarcodeReaderServiceState getState()
```
    Get the connection state.
    
    Returns:
    
    connection state. (Japanese) 接続状態を取得します。
  - start
```
public void start()
```
    Obtain a list of devices and check if there is a barcode reader. By this method, the connection state changes to BluetoothServiceState.listen. When it is in the connected state, release the connection. (Japanese) デバイスの一覧を取得して、バーコードリーダーが存在するか確認します。本メソッドによって、接続状態がBluetoothServiceState.listenに遷移します。接続状態にあるときは、一度接続を解除します。
  - stop
```
public void stop()
```
    Stop all processing related to the connection and change its state to BcrServiceState.none. This method can be used in any state of BcrServiceState. (Japanese) 接続に関するすべての処理を停止して、状態をBcrServiceState.noneにします。 BcrServiceStateがどの状態でも、本メソッドを利用することが可能です。
