[Android] Kotlin - Firebase Dynamic Link

1. Firebase 콘솔 에서 Dynamic Link 생성

2. 외부에서 접속하려는 Activity에 <intent-filter> 등록

- host에 콘솔의 [동적 링크 설정] -> [딥 링크 URL] 에 등록한 URL을 입력

 <intent-filter>
     <action android:name="android.intent.action.VIEW"/>
     <category android:name="android.intent.category.DEFAULT"/>
     <category android:name="android.intent.category.BROWSABLE"/>
     <data
            android:host="test.co.kr"
            android:scheme="https"/>
 </intent-filter>

3. createDynamicLink()

private val DEEPLINK_URL = "https://test.co.kr/"
private val SHORT_DYNAMIC_LINK = "https://test.page.link"
private val PACKAGE_NAME = "co.kr.test.dev"

private fun createDynamicLink(): String {
    return FirebaseDynamicLinks.getInstance()
        .createDynamicLink()
        .setLink(Uri.parse(DEEPLINK_URL))
        .setDomainUriPrefix(SHORT_DYNAMIC_LINK )
        .setAndroidParameters(
            DynamicLink.AndroidParameters.Builder(PACKAGE_NAME)
                .build()
        )
        .buildDynamicLink()
        .uri.toString() + "event/" + viewModel.event.event_no  //  https://URL/event/3 의 형태로 만들기 위해 추가
}

4. getDynamicLink()

FirebaseDynamicLinks.getInstance()
    .getDynamicLink(intent)
    .addOnSuccessListener {
        var deppLink: Uri? = null
        if (it != null) {
            deppLink = it.link
            val eventNo = deppLink.path!!.replace("/event/", "")
        } else {
            // handle 
        }

    }
    .addOnFailureListener {
          // handle 
    }
