如何在Android项目中集成Eclipse Milo并解决相关运行错误

• 最初尝试引入Eclipse Milo v0.6.8，编译能通过，但运行应用时出现错误
• 之后改为手动从Maven下载org.eclipse.milo/sdk-client的jar包，看起来能正常引入，但编写以下OpcUaClientConfig代码时，出现了和.stack相关的错误
• 尝试从Maven查找org.eclipse.milo/opc-ua-stack的jar包，结果只得到XML文件，目前不知道该如何推进

OpcUaClientConfig config = new OpcUaClientConfig() {

            @Override

                return null;
            }

            @Override
            public String getProductUri() {
                return null;
            }

            @Override
            public Supplier<String> getSessionName() {

            @Override
            public String[] getSessionLocaleIds() {
                return new String[0];
            }

            @Override

                return null;
            }

            @Override
            public org.eclipse.milo.opcua.stack.core.types.builtin.unsigned.UInteger getMaxResponseMessageSize() {
                return null;
            }

            @Override

                return null;
            }

            @Override
            public IdentityProvider getIdentityProvider() {
                return null;
            }

            @Override

            @Override

                return null;
            }

            @Override
            public org.eclipse.milo.opcua.stack.core.types.builtin.unsigned.UInteger getKeepAliveTimeout() {
                return null;
            }

            @Override
            public double getSubscriptionWatchdogMultiplier() {
                return 0;
            }
        };
