0.1.0

First release.

Detection

• Root (Android), jailbreak (iOS), emulator / simulator, debugger and mock location checks, through DeviceShield.check() or one method per check.
• Every result lists the signals that fired, each with a strength. A check is detected with at least one strong signal or two medium ones. Weak signals (common on custom ROMs, emulators and debug builds) never decide the result on their own.
• A check that can't run returns CheckStatus.failed; nothing throws. A check that doesn't exist on the platform returns CheckStatus.notApplicable, including jailbreak detection on the iOS Simulator.

Screen

• DeviceShield.screenshots (Android 14+ and iOS) and DeviceShield.screenRecordingChanges / isScreenRecorded() (iOS).
• setScreenshotProtection and setAppSwitcherProtection. On Android both use FLAG_SECURE, tracked separately and re-applied after configuration changes. iOS screenshot protection is experimental until verified on a device.

Platform

• Android checks run on a background thread.
• Android 14+: declares DETECT_SCREEN_CAPTURE, required for screenshot detection.
• Minimum Android API 21, iOS 15.0.
