Android minifyEnabled true for firebase

Question

我是 android 初学者，我写过这样的代码。如果我启用 minifyEnabled = true，该特定代码不会触发，我也不知道如何正确调试（我只能记录）。我该怎么办？

    DatabaseReference database = FirebaseDatabase.getInstance().getReference().child("ConversationUser").child(FirebaseAuth.getInstance().getUid());
    database.addChildEventListener(new ChildEventListener() {
        @Override
        public void onChildAdded(DataSnapshot dataSnapshot, String s) {
            ConversationUser conversationUser = dataSnapshot.getValue(ConversationUser.class);


            Log.e("Chat", conversationUser.toString());
            Log.e("Chat Status", conversationUser.getStatus());
            String status = conversationUser.getStatus();

            if (status != null && status.toLowerCase().equals("active")) {
                //TODO: this never trigger if minifyEnabled = true
                retrieveConversation(conversationUser.getId());
                EventBus.getDefault().post(new ChatDetailAdapter.ReceiveMessage());
            }
        }

        @Override
        public void onChildChanged(DataSnapshot dataSnapshot, String s) {
            Log.e("ChatHelper", "onChildChanged");

            ConversationUser conversationUser = dataSnapshot.getValue(ConversationUser.class);
            if (conversationUser.getStatus().toLowerCase().equals("delete")) {

                for(Iterator<Map.Entry<String, Conversation>> it = mainMessage.getConversations().entrySet().iterator(); it.hasNext(); ) {
                    Map.Entry<String, Conversation> entry = it.next();
                    if(entry.getKey().equals(conversationUser.getId())) {
                        it.remove();
                    }
                }

                sortConversation();
                EventBus.getDefault().post(new ChatDetailAdapter.ReceiveMessage());
            }
        }

        @Override
        public void onChildRemoved(DataSnapshot dataSnapshot) {
            EventBus.getDefault().post(new ChatDetailAdapter.RemoveMessage());
        }

        @Override
        public void onChildMoved(DataSnapshot dataSnapshot, String s) {
            EventBus.getDefault().post(new ChatDetailAdapter.ReceiveMessage());
        }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }
    });

可能您的模型很模糊，这就是您的代码无法正常工作的原因。要修复它，您需要保留存储所有FirebaseModelsproguard 文件的文件夹。

# Firebase
-keep class com.myAppPackage.folderWhereYouSaveYourModels.** { *; }

您还需要再添加几行，您可以查看文档：

在您的应用中使用 Firebase 实时数据库和 ProGuard 时，您需要考虑在混淆后如何序列化和反序列化模型对象。如果您使用 DataSnapshot.getValue(Class) 或 DatabaseReference.setValue(Object) 读取和写入数据，则需要向 proguard-rules.pro 文件添加规则：

# Add this global rule
-keepattributes Signature

# This rule will properly ProGuard all the model classes in
# the package com.yourcompany.models. Modify to fit the structure
# of your app.
-keepclassmembers class com.yourcompany.models.** {
  *;
}

希望它会帮助你！
