发布构建应用崩溃导致保护规则

Question

我的应用程序中有一堆回收器视图，可以从Firestore数据库中获取数据。在我的调试应用程序中一切正常，但是当我在我的 proguard 中添加minifyEnabled true时，一切正常，但活动主机回收器失败并出现以下 logcat 错误。我完全不知道如何为模型类添加保护规则

我刚刚做了我的堆栈跟踪，这是错误

Answer 1

可能是由于 proguard 而遇到问题，以确保尝试在您的发布构建类型中禁用 minify

buildTypes {
release {
minifyEnabled false
------
}
}

Answer 2

在保护规则中添加以下代码

-keep class package.to.yourmodels.** { *; }
-keepattributes *Annotation*
-keepattributes Signature
-dontwarn com.squareup.okhttp.*
-dontwarn rx.**
-dontwarn retrofit2.**
-keep class retrofit2.** { *; }
-keepattributes Exceptions
-keepattributes RuntimeVisibleAnnotations
-keepattributes RuntimeInvisibleAnnotations
-keepattributes RuntimeVisibleParameterAnnotations
-keepattributes RuntimeInvisibleParameterAnnotations
