Manual installation

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-screenshot-detector and add RnScreenShot.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRnScreenShot.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Android

1. Open up android/app/src/main/java/[...]/MainApplication.java

• Add import com.reactlibrary.RnScreenShotPackage; to the imports at the top of the file
• Add new RnScreenShotPackage() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:

   include ':react-native-screenshot-detector'
   project(':react-native-screenshot-detector').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-screenshot-detector/android')

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     compile project(':react-native-screenshot-detector')

Usage

import { DisableScreenShot, EnableScreenShot } from 'rn-screenshot-detector'


componentDidMount(){
	...
	DisableScreenShot(this.callBack);
}

componentWillUnmount(){
	...
	EnableScreenShot()
}

callBack=()=>{
Alert.alert("Warning","It isn't safe to take a screenshot")
}

For ios, we can not disable screenshot, so we just detect action screenshot. For android, any action screenshot or recording screen will be return black screen.
