React Native Screenshot Aware

npm version npm downloads license

Real-time screenshot detection for React Native apps

Features

  • 🚀 Real-time screenshot detection
  • 🔄 Cross-platform support (iOS & Android)
  • 🎣 Easy-to-use React hooks
  • ⚡ Optimized for performance
  • 📱 Supports Android 14+ (API level 34+) and iOS 14+
  • 🏗️ Supports the new architecture for React Native

Installation

yarn add react-native-screenshot-aware

or

npm install react-native-screenshot-aware

Important Notes

Android

  • Supports Android 14+ (API level 34 and above)
  • Utilizes the latest Android API for efficient screenshot detection
  • Leverages the new DETECT_SCREEN_CAPTURE permission introduced in Android 14
  • Provides a more privacy-friendly and performant approach to screenshot detection

Permissions

To use the screenshot detection feature on Android, you need to add the following permission to your AndroidManifest.xml file:

<uses-permission android:name="android.permission.DETECT_SCREEN_CAPTURE" />

Note: Callbacks will never be triggered on devices running Android versions below 14. This is due to the reliance on the new DETECT_SCREEN_CAPTURE permission and APIs introduced in Android 14, which are not available in earlier versions.

Note: The decision to support only Android 14+ is based on the introduction of new, dedicated screenshot detection APIs. These APIs offer improved performance and respect user privacy better than previous methods. For more details, see the Android 14 screenshot detection documentation.
