web3sdk 2.6.1启动时出现如下错误：

原因：
netty-all-4.1.52 版本做了升级，使用了较高版本的tcnative的内部变量，导致NoSuchFieldError异常，web3sdk无法初始化成功

解决方法，下面两种解决方案任选其一即可：
1. 使用netty<=4.1.51的版本

2. 使用`web3sdk`<=`2.5.1`的版本，并且添加下列依赖：

compile 'io.netty:netty-tcnative:2.0.27.Final'
compile 'io.netty:netty-tcnative-boringssl-static:2.0.27.Final'

我使用第1种方法，web3sdk版本2.6.1，netty-all:4.1.9.Final版本，web3sdk启动报如下错误：

使用第2种方法，web3sdk版本改成2.5.1，就不会报异常
