Linking
RN v0.60+
From React native v0.60 and above, linking is automatic. So you don't need to run react-native link anymore. Refer here.
iOS
After the the automatic scripts completed successfully, run pod install and you're good to go:
pod install
RN v0.59 (Deprecated)
I highly recommend to update your current React Native project to at least
0.68+or higher to keep up-to-date with community, reducing issues and bug fixing, also New Architecture supported.
React-native 0.59 and lower: Please do manual installation as follow
iOS
- 
In XCode, in the project navigator, right click Libraries➜Add Files to [your project's name]
- 
Go to node_modules➜react-native-screenguardand addScreenGuard.xcodeproj
- 
In XCode, in the project navigator, select your project. Add libScreenguard.ato your project'sBuild Phases➜Link Binary With Libraries
Android
- Open up android/app/src/main/java/[...]/MainActivity.java
- 
Add import com.screenguard.ScreenGuardPackage;to the imports at the top of the file
- 
Add new ScreenGuardPackage()to the list returned by thegetPackages()method
- Append the following lines to android/settings.gradle:
include ':react-native-screenguard'
project(':react-native-screenguard').projectDir = new File(rootProject.projectDir,'../node_modules/react-native-screenguard/android')
- Insert the following lines inside the dependencies block in android/app/build.gradle:
  compile project(':react-native-screenguard')
Post installation for Android
In order to get this works correctly on Android, you must declare an activity name com.screenguard.ScreenGuardColorActivity inside your project AndroidManifest.xml
as you will not receive the background color or the blur effect like in the video example.
Note: Updated on
v1.0.8is no longer required as this activity has been declared insideAndroidManifestof the library, and merged with the project's Manifest file when start building.Only do this step if you are using
v1.0.6or below
- Open up [your_project_path]/android/app/src/main/AndroidManifest.xmland add activitycom.screenguard.ScreenGuardColorActivitylike below
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
