Firebase 数据库 - Firebase 数据库运行循环中未捕获的异常 (19.3.0)

Question

我在项目中遇到了这个问题，但不知道如何解决。请帮帮我。

我的项目之前（11.8.0）已经实现了firebase data并且运行正常。我最近添加了 firebase crashlytics sdk（数据库更新到 19.3.0），并在以发布模式（minifyEnable = true）运行项目时崩溃。

我的 gradle 文件

implementation("com.google.firebase:firebase-core:17.4.1")
    implementation("com.google.firebase:firebase-analytics:17.2.3")
    implementation("com.google.firebase:firebase-messaging:20.1.7")
    implementation("com.google.firebase:firebase-database:19.3.0")
    implementation("com.google.firebase:firebase-auth:19.3.1")
    implementation("com.google.firebase:firebase-crashlytics:17.0.0")

我的代码

FirebaseDatabase database = FirebaseDatabase.getInstance();

        DatabaseReference dbRef = database.getReference("/mydbkey");
        dbRef.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(DataSnapshot dataSnapshot) {
               // Do my stuff
            }

            @Override
            public void onCancelled(DatabaseError databaseError) {
                // Do my stuff
            }
        });

崩溃的消息：
