In XCode, in the project navigator, right click `Libraries` ➜ `Add Files to [your project's name]` 18 | 2. Go to `node_modules` ➜ `react-native-fingerprint-change` and add `RNFingerprintChange.xcodeproj` 19 | 3. In XCode, in the project navigator, select your project. Add `libRNFingerprintChange.a` to your project's `Build Phases` ➜ `Link Binary With Libraries` 20 | 4. Run your project (`Cmd+R`)< 21 | 22 | #### Android 23 | 24 | 1. Open up `android/app/src/main/java/[...]/MainApplication.java` 25 | - Add `import com.toyberman.fingerprintChange.RNFingerprintChangePackage;` to the imports at the top of the file 26 | - Add `new RNReactNativeAccessibilityPackage()` to the list returned by the `getPackages()` method 27 | 2. Append the following lines to `android/settings.gradle`: 28 | ``` 29 | include ':react-native-fingerprint-change' 30 | project(':react-native-fingerprint-change').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-fingerprint-change/android') 31 | ``` 32 | 3.
