Why can't gRPC cann't re-establish the channel when channel failed. which Okhttp work fine.

[1wayticket]

I have an app which communicate with server by grpc。when app go foreground，I need send my status to server and so on。

As the Android OS limit，the app may lost connection when restart,like 1。So I #need to call resetConnectBackoff refer from issus。
So why grpc cann’t reconnect when channel is failure？
I have viewed AndroidChannelBuilder which observer net connection，the reconnect and request may happend same time，It‘s alse not the right answer。
So，I‘m confused

The behavior you're seeing is expected due to gRPC's connection backoff policy.
Using resetConnectBackoff() when your app comes to the foreground is the correct and intended way to force an immediate reconnection attempt.
