Answer 1

Go to android/build.gradle and in repositories add

        maven {
        // expo-camera bundles a custom com.google.android:cameraview
        url "$rootDir/../node_modules/expo-camera/android/maven"
    }

then in terminal cd android and gradlew clean then go back to your project folder and try again npx react-native run-android
