Android 17 Blocks Non-Accessibility Apps from Accessibility API to Prevent Malware Abuse

Android 17 introduces a restriction in Advanced Protection Mode (AAPM) that blocks non-accessibility apps from accessing the accessibility services API to prevent malware abuse.

• •AAPM, introduced in Android 16, places devices in a heightened security state similar to Apple's Lockdown Mode, trading usability for reduced attack surface.
• •In Android 17 Beta 2, apps not classified as accessibility tools are blocked from using the accessibility services API when AAPM is active.
• •Only apps with the isAccessibilityTool="true" flag—screen readers, switch-based input, voice-based input, and Braille tools—are exempt from this restriction.
• •Non-accessibility apps that already hold accessibility permissions will have those privileges automatically revoked when AAPM is enabled.
