设置minifyEnabled true时出现以下错误：
找不到为 com.codeworks.myapp.FirestoreModel 生成的 Parcelable 类，请验证您的类是否配置正确以及 Parcelable 类 com.codeworks.myapp.FirestoreModel$$Parcelable 是由 Parceler 生成的。
我将以下代码放置在parceler.org网站中的proguard-rules.pro中：
# Parceler configuration
-keep interface org.parceler.Parcel
-keep @org.parceler.Parcel class * { *; }
-keep class **$$Parcelable { *; }
-keep class org.parceler.Parceler$$Parcels
...并在FirestoreModel和 Fragment 的类中添加了@Keep注释：
@Parcel
@Keep
class FirestoreModel{
...
}
@Keep
class MyFragment: Fragment() {
...
}
然后添加了一些pro-guard 规则，或者我从 stackoverflow.com 的示例中理解（因为我无法理解官方文档中的规则）：
-keepnames class com.codeworks.myapp.MyFragment { *; }
-keepnames class com.codeworks.myappFirestoreModel { *; }
我仍然收到以下错误：

显然，MyFragment 上的 onViewCreated 函数的变量名称正在被重命名，尽管有pro-guard规则。
错误似乎指向这一行：
// Here... at com.codeworks.myapp.MyFragment$onViewCreated$1.a(:68)
adapter = object : FirestoreRecyclerAdapter<DpMemoModel, DpViewHolder>(options) {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): FirestoreViewHolder{
val view : View = LayoutInflater.from(parent.context).inflate(R.layout.firestore_cardview, parent, false)
return FirestoreViewHolder(view)
}
override fun onBindViewHolder(
holder: FirestoreViewHolder,
position: Int,
model: FirestoreModel
) {
...
// ...and Here: **at com.codeworks.myapp.MyFragment$onViewCreated$1.a(:103)**
val wrapped : Parcelable = Parcels.wrap(model)
holder.cardView.setOnClickListener {
val intent= Intent(activity, FirestoreInfoActivity::class.java)
intent.putExtra("parcel", wrapped)
startActivity(intent)
}
PS：我正在使用 FirestoreRecyclerAdapter，我认为这是处理 Cloud Firestore 和 Firebase Storage 数据以来最好的方法。
