Java のコード例: ゲーム オプションおよびトレーラーを含むアプリの申請

この記事では、次のタスクで Microsoft Store 申請 API を使用する方法を示す Java コード例を提供します。

  • Microsoft Store 申請 API で使用する Azure AD アクセス トークンを取得します。
  • アプリの申請の作成
  • ゲームトレーラーの高度な登録情報のオプションを含む、アプリの申請用のストア登録情報データを構成します。
  • アプリの申請用のパッケージ、登録情報の画像、トレーラー ファイルが含まれた ZIP ファイルをアップロードします。
  • アプリの申請をコミットします。

アプリの申請の作成

CreateAndSubmitSubmissionExample クラスは、他のサンプル メソッドを呼び出して Microsoft Store 申請 API を使用して、ゲーム オプションとトレーラーを含むアプリの申請を作成およびコミットするmain プログラムを実装します。 このコードを採用するには、次の手順を実行してください。
