The number of method references in a .dex file cannot exceed 64k API 17

android/app/build.gradle에서 다음과 같이 multiDexEnabled를 true로 설정한다.

defaultConfig {
    applicationId "com.front_rn"
    minSdkVersion rootProject.ext.minSdkVersion
    targetSdkVersion rootProject.ext.targetSdkVersion
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}
