Fungsi inti

Android 17 menambahkan fitur baru berikut yang terkait dengan fungsi Android inti.

Pemicu ProfilingManager baru

Android 17 adds several new system triggers to ProfilingManager to help you collect in-depth data to debug performance issues.

The new triggers are:

TRIGGER_TYPE_COLD_START: Trigger occurs during app cold start. It provides both a call stack sample and a system trace in the response.
TRIGGER_TYPE_OOM: Trigger occurs when an app throws an OutOfMemoryError and provides a Java Heap Dump in response.
TRIGGER_TYPE_KILL_EXCESSIVE_CPU_USAGE: Trigger occurs when an app is killed due to abnormal and excessive CPU usage and provides a call stack sample in response.

To understand how to set up the system trigger, see the documentation on trigger-based profiling and how to retrieve and analyze profiling data documentation.

Keamanan

Android 17 menambahkan fitur baru berikut untuk meningkatkan keamanan perangkat dan aplikasi.

Mode Perlindungan Lanjutan Android (AAPM)

Android Advanced Protection Mode offers Android users a powerful new set of security features, marking a significant step in safeguarding users—particularly those at higher risk—from sophisticated attacks. Designed as an opt-in feature, AAPM is activated with a single configuration setting that users can turn on at any time to apply an opinionated set of security protections.

These core configurations include blocking app installation from unknown sources (sideloading), restricting USB data signaling, and mandating Google Play Protect scanning, which significantly reduces the device's attack surface area. Developers can integrate with this feature using the AdvancedProtectionManager API to detect the mode's status, enabling applications to automatically adopt a hardened security posture or restrict high-risk functionality when a user has opted in.

Konektivitas

Android 17 menambahkan fitur berikut untuk meningkatkan konektivitas perangkat dan aplikasi.

Jaringan satelit yang dibatasi

Menerapkan pengoptimalan agar aplikasi dapat berfungsi secara efektif melalui jaringan satelit dengan bandwidth rendah.

Pengalaman pengguna dan UI sistem

Android 17 menyertakan perubahan berikut untuk meningkatkan pengalaman pengguna.

Handoff

Handoff is a new feature and API coming to Android 17 that app developers can integrate with to provide cross-device continuity for their users. It allows the user to start an app activity on one Android device and transition it to another Android device. Handoff runs in the background of a user's device and surfaces available activities from the user's other nearby devices through various entry points, like the launcher and taskbar, on the receiving device.

Apps can designate Handoff to launch the same native Android app, if it is installed and available on the receiving device. In this app-to-app flow, the user is deep-linked to the designated activity. Alternatively, app-to-web Handoff can be offered as a fallback option or directly implemented with URL Handoff.

Handoff support is implemented on a per-activity basis. To enable Handoff, call the setHandoffEnabled() method for the activity. Additional data may need to be passed along with the handoff so the recreated activity on the receiving device can restore appropriate state. Implement the onHandoffActivityRequested() callback to return a HandoffActivityData object which contains details that specify how Handoff should handle and recreate the activity on the receiving device.
