문의 시, 사용하시는 SDK 버전 정보와 디벨로퍼스 앱ID를 알려주세요.
Faq 목록 - 10. Android ( Faq 목록 입니다 ) 먼저 확인해주세요.
SDK 버전: 26 ~ 34
buildTypes {
getByName("debug") {
isShrinkResources = false
isMinifyEnabled = false
isDebuggable = true
signingConfig = signingConfigs.getByName("debug")
}
getByName("release") {
isShrinkResources = false
isMinifyEnabled = false
isDebuggable = false
proguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"), "proguard-rules.pro")
proguardFile("proguard-kakao.pro")
proguardFile("proguard-retrofit2.pro")
signingConfig = signingConfigs.getByName("release")
}
}
위와 같이 buildType을 설정하고 나서 release로 빌드하고 앱을 run해서 로그인을 시도하면 네트워크상으로는 로그인에 성공하지만 다음 화면으로 넘어가지 못하고 다음과 같은 오류가 발생합니다.
위에 보이는 at a3.c.s와 at i8.b.onResponse를 보고 나서 build → outputs → mapping → release → mapping.txt를 열어서 관련 부분을 찾아보니 다음과 같았습니다.
com.google.android.datatransport.runtime.backends.BackendResponse$Status$EnumUnboxingLocalUtility -> a3.c
com.kakao.sdk.auth.model.OAuthToken refreshToken$auth_release(com.kakao.sdk.auth.model.OAuthToken):0:0 -> a
com.kakao.sdk.auth.AuthApiManager$agt$1$1 -> i8.b:
프로가드(proguard.pro) 파일에 카카오 디벨로퍼스(시작하기 | Kakao Developers 시작하기)에서 제시하는 코드를 넣었는데도 이런 오류가 발생하네요.
retrofit 관련 proguard 코드는 다음과 같이 작성했습니다.
# Retrofit does reflection on generic parameters. InnerClasses is required to use Signature and
# EnclosingMethod is required to use InnerClasses.
-keepattributes Signature, InnerClasses, EnclosingMethod
# Retrofit does reflection on method and parameter annotations.
-keepattributes RuntimeVisibleAnnotations, RuntimeVisibleParameterAnnotations
# Keep annotation default values (e.g., retrofit2.http.Field.encoded).
-keepattributes AnnotationDefault
# Retain service method parameters when optimizing.

##---------------Begin: proguard configuration for Gson ----------

카카오 관련 proguard는 다음과 같습니다. (2024-01-19 수정)
-keep class com.kakao.sdk.**.model.* { <fields>; }
-keep class * extends com.google.gson.TypeAdapter
# https://github.com/square/okhttp/pull/6792

-dontwarn org.openjsse.**

로그인 관련 data class에는 모두 @Keep을 붙였는데도 오류가 발생하는데
뭐가 문제인지 도저히 모르겠어서 질문 드립니다.
