このガイドでは、Android Dynamic Performance Framework（ADPF）を使用して、Android の動的な温度と CPU 管理機能に基づいてゲームを最適化する方法について説明します。ここでは主にゲームに焦点を当てますが、この機能をパフォーマンス重視の他のアプリで使用することもできます。
ADPF は、ゲームや高いパフォーマンスを必要とするアプリが Android デバイスの電力システムや温度システムをより直接的に操作できるようにする API のセットです。これらの API を使用することで、Android システムでの動的な動作をモニタリングし、デバイスを過熱状態にしない持続可能なレベルでゲームのパフォーマンスを最適化することができます。

The focus is on games, but you can also use the features for other\nperformance-intensive apps.\n\nADPF is a set of APIs that allow games and performance-intensive apps to\ninteract more directly with power and thermal systems of Android devices. With\nthese APIs, you can monitor the dynamic behavior on Android systems and optimize\ngame performance at a sustainable level that doesn't overheat devices.\n\nMobile SoCs and Android have more dynamic performance behaviors than desktops\nand consoles. These behaviors include thermal state management, varying CPU\nclocks, and varying CPU core types. This combined with the increasingly diverse\ncore topology of SoCs creates challenges when trying to ensure that your game\ncan take advantage of this behavior without negatively impacting device\nperformance. ADPF provides some of this information in order to make performance\nmore predictable.\n\nHere are the main ADPF features:\n\n- **Thermal API**: Monitor the thermal state of a device so that the application can proactively adjust workload before it becomes unsustainable.\n- **CPU Performance Hint API**: Provide performance hints that let Android choose the right performance settings (for example, CPU operating point or core) for the workload.\n- **Game Mode API \\& Game State API**: Enable game play optimization by prioritizing performance or battery life characteristics, based on user's settings and game specific configurations.\n- **Fixed Performance Mode**: Enable fixed-performance mode on a device during benchmarking to get measurements that aren't altered by dynamic CPU clocking.\n- **Power Efficiency Mode** : Tells the session that the threads in Performance Hint Session can be safely scheduled to prefer power efficiency over performance.
