求救，android netty的问题 java.io.IOException: Software caused connection abort

[a1111111984]

最近在android上做的一个简单的netty客户端，基本上是按照官网上的例子来做的
http://netty.io/4.1/xref/io/netty/example/securechat/package-summary.html

ChatClient：
final SslContext sslCtx = SslContextBuilder.forClient().trustManager(InsecureTrustManagerFactory.INSTANCE).build();
bootstrap = new Bootstrap()
.group(group)
.channel(NioSocketChannel.class)
.handler(new SecureChatClientInitializer(sslCtx,user_code));

bootstrap.option(ChannelOption.SO_KEEPALIVE,true);
bootstrap.option(ChannelOption.TCP_NODELAY,true);
bootstrap.option(ChannelOption.SO_TIMEOUT, 5000);

cf = bootstrap.connect(new InetSocketAddress(HOST, PORT));

SecureChatClientInitializer：
pipeline.addLast(sslCtx.newHandler(ch.alloc(), HOST, PORT));

// On top of the SSL handler, add the text line codec.
pipeline.addLast(new DelimiterBasedFrameDecoder(8192, Delimiters.lineDelimiter()));
pipeline.addLast(new StringDecoder());
pipeline.addLast(new StringEncoder());
pipeline.addLast("ping", new IdleStateHandler(5, 5, 5 * 3, TimeUnit.SECONDS));

// and then business logic.
pipeline.addLast(new SecureChatClientHandler(usercode));

SecureChatClientHandler：

public void channelRead0(ChannelHandlerContext ctx, String msg) throws Exception {
System.err.println(msg);
}

@Override
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) {
cause.printStackTrace();
ctx.close();
}

netty客户端写在service里面，诡异的是app页面保持活动的时候接收和发送消息都正常，用usb线连在电脑调试的时候也正常，一旦拔掉调试线，并把APP放在后台运行的时候，过大概40s左右的时间服务器就会出现连接丢失的情况，重新连上后可以重连，并报这样的错误 java.io.IOException: Software caused connection abort

可以确定的是service一直是在运行没有被杀掉，但为什么会出现这么奇怪的事情，

连接上调试线和没连上具体有什么区别？
求大侠告知

自己占1楼，先顶为敬

需要 做 Service 保活 处理 ; 前台 和 可见 服务 一般不会被回收; 服务 如果 进入 后台 , 就容易被杀死 ;
结合 Service 保活, 实现 Socket 长连接 ;

给一个 Service 保活的 参考方案 : https://www.jianshu.com/p/22a708c74c1e

楼主解决了吗?我也出现这个问题 不是保活的问题、我的Service是单起的一个进程、进程没被杀死、所以不是Service的问题

是哪一步调用出现java.io.IOException: Software caused connection abort异常？ 是连接时、发送数据时还是接收数据时？

贴上堆栈来看一下

我也出现相同问题，报错异常如下：

我的跟13楼一样，这个是说明在接受数据时出现的报错对吧？
