Kotlin :启用 proguard 后应用程序崩溃

Question

我编写了这个模型类来从 Firbase 数据库获取配置

@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

你的gradle防护线是这样的吗？

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

问题也可能出在@Keep，因为您的@SerializedName和变量名称相同。因此，请尝试删除@Keep或保留@Keep注释，而是将变量重命名为小写变量，看看它是否有效。
