# 2.x から 3.0 に移行

Thales SDK 3.0.0 以降、いくつかの公開 API が簡素化されました。

## 名前が変更されたクラスと API <a href="#renamed-classes-and-apis" id="renamed-classes-and-apis"></a>

* [PendingBindingSession.java](https://thalesgroup.github.io/d1sdk-docs/tmg-sdk/android/2.0.0/com/thalesgroup/tmgsdk/PendingBindingSession.html) から [IDVSession.java](https://thalesgroup.github.io/d1sdk-docs/tmg-sdk/android/3.0.0/com/thalesgroup/tmgsdk/IDVSession.html).
* [PendingBindingSession.submitIdvMethod()](https://thalesgroup.github.io/d1sdk-docs/tmg-sdk/android/2.0.0/com/thalesgroup/tmgsdk/PendingBindingSession.html#submitIdvMethod\(com.thalesgroup.tmgsdk.IDVMethod\)) から [IDVSession.selectIdvMethod()](https://thalesgroup.github.io/d1sdk-docs/tmg-sdk/android/3.0.0/com/thalesgroup/tmgsdk/visa/IDVSession.html#selectIdvMethod\(com.thalesgroup.tmgsdk.visa.IDVMethod\)).

## 名前が変更されたパッケージ <a href="#renamed-package" id="renamed-package"></a>

* Visa 固有のクラスは `visa` パッケージに移動しました： [VisaCTFHelper](https://thalesgroup.github.io/d1sdk-docs/tmg-sdk/android/3.0.0/com/thalesgroup/tmgsdk/visa/VisaCTFHelper.html), [TokenBindingListener](https://thalesgroup.github.io/d1sdk-docs/tmg-sdk/android/3.0.0/com/thalesgroup/tmgsdk/visa/TokenBindingListener.html), [IDVSession](https://thalesgroup.github.io/d1sdk-docs/tmg-sdk/android/3.0.0/com/thalesgroup/tmgsdk/visa/IDVSession.html), [IDVMethod](https://thalesgroup.github.io/d1sdk-docs/tmg-sdk/android/3.0.0/com/thalesgroup/tmgsdk/visa/IDVMethod.html), [IDVType](https://thalesgroup.github.io/d1sdk-docs/tmg-sdk/android/3.0.0/com/thalesgroup/tmgsdk/model/visa/IDVType.html)onFilterTouchEventForSecurity [OtpActivationStatus](https://thalesgroup.github.io/d1sdk-docs/tmg-sdk/android/3.0.0/com/thalesgroup/tmgsdk/model/visa/OtpActivationStatus.html).

Visa と Mastercard のクラス名が同一であるため、曖昧な参照エラーを回避するために次の変更を推奨します：

* Java では、Visa と Mastercard の API 呼び出しを別々のクラスに分けてください。同一クラス内で Visa と Mastercard の両方の API を呼び出すために完全修飾名（クラス名とパッケージ）を使用することは推奨されません。
* Kotlin では、パッケージエイリアス機能を次の `as` キーワードで使用してください：

```kotlin
import com.thalesgroup.tmgsdk.visa.IDVMethod as VisaIDVMethod
import com.thalesgroup.tmgsdk.mastercard.IDVMethod as MasterCardIDVMethod

fun main() {
 var visaIDVMethod: VisaIDVMethod
 var masterCardIDVMethod: MasterCardIDVMethod
}
```

## 削除されたクラスと API <a href="#removed-classes-and-apis" id="removed-classes-and-apis"></a>

* [TMGClientConfiguration.Builder](https://thalesgroup.github.io/d1sdk-docs/tmg-sdk/android/2.0.0/com/thalesgroup/tmgsdk/TMGClientConfiguration.Builder.html)：すべての構成オプションは [TMGClientConfiguration](https://thalesgroup.github.io/d1sdk-docs/tmg-sdk/android/3.0.0/com/thalesgroup/tmgsdk/TMGClientConfiguration.html) コンストラクタに移されました。
