Shadowsocks-android: 流量速度计显示的速度始终为 0

[pexcn]

基于 master 分支的最新代码的 bug：https://github.com/shadowsocks/shadowsocks-android/tree/265ecc04066092665b27e1779b77b1bf404d965f

VPN 模式，连接上去了点测试速度，显示始终为 0.

EDIT: 忘记把 IP 打码了...

[Mygod]

It seems like a race condition somewhere in ServiceBoundContext.

[madeye]

I cannot reproduce it locally. Any related change recently? @Mygod

[Mygod]

It's very hard to reproduce. I've only seen it like 4 times so far. I might be wrong but it seems to only happen immediately after an update.

[pexcn]

@Mygod @madeye 我从旧版本升级上去，Service mode 选择 Proxy only，尝试连接，断开，再选择 Transproxy，尝试连接，断开，最后选择 VPN，连接，测延迟，就能出现这种情况。只出现过一次，后来就没再尝试了

[Mygod]

This bug actually has been around longer than I'd like to admit but since it only happens very occasionally I can't fix it.

[madeye]

OK, I followed the way described in https://github.com/shadowsocks/shadowsocks-android/issues/1452#issuecomment-345138613 and got it reproduced.

Change to proxy mode -> Connect -> Disconnect -> Change to VPN mode -> Connect -> Reproduced.

[madeye]

It looks related to the newly added proxy only mode.

[pexcn]

Change to proxy mode -> Connect -> Disconnect -> Change to VPN mode -> Connect -> Reproduced.
然后显示始终 0 kb 的时候，退出应用界面之后重新进入 或 关闭再打开屏幕，就正常显示速度了

[madeye]

@pexcn It's because the background service is forced to reconnected again.

It seems not. The service didn't need to reconnected.

[madeye]

It'd be a misbehavior of the bandwidth listener's state:

I'll look into it and try some fixes.
