リリース済みで安定版のプラットフォーム用のファクトリー イメージについては、Nexus デバイスおよび 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 イメージをフラッシュするには、デバイスを完全にリセットする必要があるため、最初に必ずデータをバックアップしてください。各ビルドは、以下の Google Pixel デバイスで利用できます。
- Pixel 6 および Pixel 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 8a
- Google Pixel 9、Google Pixel 9 Pro、Google Pixel 9 Pro XL、Google Pixel 9 Pro Fold
- Google Pixel 9a
サポートされている 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 ベータ版プログラムに自動的に登録され、プログラムからこの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 など）に対する無線（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 Android 16 QPR2 を入手するその他の方法については、Android 16 QPR2 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、次のリンクを使用して Android Flash Tool に移動して、画面に表示される手順を実施します。 https://flash.android.com/preview/baklava-qpr2-beta1。
デバイスに手動で書き込む
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。
