mina4-android description

Android TCP框架(基于MINA 2.0.0-M3)、增加Bytes工厂、无需依赖slf4j(新增Mina4Log打印输出日志)，
处理Bytes粘包、半包、断包(ByteArrayDecoder)，需配置自己的首尾标识符，
如果与首尾标识符相同的数据出现在首尾标识符以内的范围，建议将该数据进行转义，
如这样配置转义规则(假设首尾标识符是0x7e)：

0x7e = 0x7d,0x02 如果首尾以内出现标识符，将其转换为0x7d后面紧跟一个0x02
0x7d = 0x7d,0x01 如果首尾以内出现标识符转义字符，不进行转换，在其后面紧跟一个0x01

mina4-android Suggest

如果接收方与发送方的数据类型不一致时，会出现类型转换异常，需要服务端与客户端的收发数据类型保持一致，
如果服务端是在不可控范围，就是说服务端不是自己公司的，是第三方的，你无法决定它的收发数据类型，
请实现ProtocolCodecFactory，进行业务的拓展
