Google Pixel のファクトリー イメージ

Google は Android 14 の初回リリース以降、修正と改善を行ってプラットフォームを更新し続け、その後、サポート対象のデバイスにロールアウトします。このリリースは、Quarterly Platform Releases(QPR)から四半期ごとに行われます。QPR は、Feature Drop の一環として、AOSP と Google Pixel デバイスの両方に配信されます。

これらのアップデートには、アプリに影響を与える API の変更は含まれていませんが、最新の QPR ベータ版ビルドのイメージが用意されているため、必要に応じてこれらのビルドでアプリをテストできます(アプリのユーザー エクスペリエンスに影響を与える可能性がある新機能がある場合など)。

リリース済みの安定版のプラットフォームのファクトリー イメージを確認するには、Nexus デバイスと Pixel デバイスのファクトリー イメージをご覧ください。

サポートされている Google Pixel デバイスを使用するデベロッパーは、テストと開発用にデバイスを手動で最新のビルドにアップデートできます。ファクトリー イメージを書き込むにはデバイスを完全にリセットする必要があります。最初に必ずデータをバックアップしてください。ビルドは以下の Google Pixel で利用できます。

  • Google Pixel 5a
  • Google Pixel 6 および 6 Pro
  • Google Pixel 6a
  • Google Pixel 7 および 7 Pro
  • Google Pixel 7a
  • Google Pixel Fold
  • Google Pixel Tablet
  • Google Pixel 8 および Google Pixel 8 Pro
Google Pixel デバイスにベータ版ビルドを書き込むと、デバイスは Pixel 用 Android ベータ プログラムに自動的に登録され、プログラムからデバイスの登録を解除するまで、最新のベータ版ビルド(QPR を含む)への無線(OTA)アップデートが継続的に提供されます。また、書き込み可能なイメージがマイルストーンごとに提供されるため、ご使用のテスト環境に最適な方法を選択できます。

対応デバイスを最新のビルドに更新するには、下記のリンクと手順をご利用ください。テストと開発用に QPR3 を入手するその他の方法については、Android 14 QPR ベータ版ビルドを入手するをご覧ください。

Android Flash Tool を使用してデバイスに書き込む

Android Flash Tool を使用すると、サポートされている Google Pixel デバイスにシステム イメージを安全に書き込めます。Android Flash Tool は、Chrome や Edge 79 以降など、WebUSB に対応している任意のウェブブラウザで動作します。

Android Flash Tool は、デバイスに書き込む方法を順を追って案内します。ツールをインストールする必要はありませんが、デバイスのロックを解除して、開発者向けオプションで USB デバッグを有効にする必要があります。詳細な手順については、Android Flash Tool のドキュメントをご覧ください。

USB 経由でデバイスを接続し、https://flash.android.com/preview/udc-qpr3-beta1 のリンクを使用して Android Flash Tool に移動し、画面上の手順に沿って操作します。

デバイスに手動で書き込む

Android ブランドロゴ

最新のシステム イメージをダウンロードして、手動でデバイスに書き込むこともできます。テストデバイス用のシステム イメージは、下の表からダウンロードできます。テスト環境をきめ細かく管理する必要がある場合や、自動テストを行うときのように頻繁に再インストールする必要がある場合は、手動でデバイスに書き込む方法が便利です。

デバイスデータをバックアップし、以下の該当するシステム イメージをダウンロードしてから、そのイメージをデバイスに書き込むことができます。

いつでも最新の公開ビルドに戻ることができます。
