ScreenShield is a robust Kotlin library designed to safeguard your Android app's sensitive content by preventing screenshots and screen recordings. Built with Jetpack Compose, this library leverages Android's FLAG_SECURE flag to automatically protect your app's screens while they are active, ensuring that confidential information remains secure.

ScreenShield offers a seamless and efficient solution for enhancing your app's privacy. Part of the library's implementation is based on the work by @ahmetfurkhans, which inspired this effective approach.

• Screenshot Protection: Blocks users from taking screenshots of protected screens within your app.
• Screen Recording Prevention: Disables screen recording while your app is in the foreground, ensuring sensitive information cannot be captured.
• Lifecycle Integration: Automatically applies protection when your app is in use and removes it when the app goes into the background.

To integrate ScreenShield into your Jetpack Compose project, simply drag and drop ScreenShield.kt into your codebase, add import ScreenShield where you want to use it and wrap the content you wish to protect with it.

import ScreenShield

@Composable
fun YourProtectedScreen() {
    ScreenShield {
        // Your protected UI content
    }
}

By wrapping your composables with AntiSS, you ensure that screenshots and screen recordings are blocked whenever the screen is active.

ScreenShield uses Android's WindowManager.LayoutParams.FLAG_SECURE flag to prevent screenshots and screen recordings. The library is lifecycle-aware, automatically managing protection based on the current state of the app. Whether your app is in the foreground or background, ScreenShield ensures that your content is secure.

1. AntiSS Composable: The central composable that blocks screenshots and recordings.
2. ComposableLifeCycle: A lifecycle-aware composable that triggers protection based on the app's state.
3. findActivity(): A helper function that retrieves the current activity, essential for applying window flags.
