Kotlin：启用proguard后应用程序崩溃

Question

我已经编写了这个模型类来从 Firbase 数据库中获取配置

    @Keep
    class Configuration {

        @SerializedName("BASE_API_URL")
         var BASE_API_URL: String = ""

        @SerializedName("BASE_URL")
        var BASE_URL: String = ""
    }

我收到以下错误。启用proguard后

com.google.firebase.database.DatabaseException: Found two getters or fields with conflicting case sensitivity for property: base_api_url

Answer 1

您的gradle proguard 行看起来像这样吗？

proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

@Keep 也可能存在问题，因为您的@SerializedName 和变量名相同。因此，请尝试删除 @Keep 或保留 @Keep 注释，然后将变量重命名为小写，看看是否可行。
