ANDROID 17 introduces Advanced Protection Mode (AAPM), a feature designed to block non-accessibility apps from using the Accessibility API to curb malware abuse. The change, first reported by Android Authority and included in Android 17 Beta 2, aims to prevent apps from spying on users, stealing data, or controlling devices through accessibility services.
The update tightens security by blocking installs from unknown sources, restricting USB data access, and mandating Google Play Protect scans, while limiting the Accessibility Services API to verified accessibility tools marked with the isAccessibilityTool="true" flag. Developers can detect when the mode is enabled using the AdvancedProtectionManager API to adapt apps and enforce stronger security controls.
According to Google, only tools such as screen readers, switch-input systems, voice input tools and Braille access apps qualify as accessibility tools, while other apps like antivirus or password managers do not. Android 17 also introduces a contacts picker that lets apps request access to specific contact fields, limiting data exposure and improving privacy. March 16, 2026.
