build.gradle:

 implementation 'io.grpc:grpc-okhttp:1.33.1'
 implementation 'io.grpc:grpc-protobuf:1.33.1'
 implementation 'io.grpc:grpc-stub:1.33.1'

I have used ManagedChannel for grpc call in android:

fun provideGrpcChannel( host: String, port:Int) :  ManagedChannel {
        return OkHttpChannelBuilder.forAddress( host, port)
             .usePlaintext()
            .build()
}

I'm getting unable to resolve host in android when I'm opening the app from the background in some time. My network connection is good also HTTP requests are working by retrofit. The only problem is in the grpc call. After reopening the app everything is working fine as expected.

Is there any way to handle the above issue??

We might need more logs/strack traces to know the issue. I am suspecting dns resolution problems in your environment, or dns cache. If you can produce it again, could you provide more logs.

@YifeiZhuang I'm seeing what is probably the same, in the context of https://github.com/firebase/firebase-android-sdk, which use gRPC.

With logging enabled, they seem to be doing the right thing:

  • When the app goes into standby the gRPC layer seems to fairly quickly detect that Android has killed the connection (probably to conserve power)
  • After leaving the device off for 5 minutes and turning on the screen again they log the following: I/Firestore(31596): (24.0.1) [AndroidConnectivityMonitor]: App has entered the foreground.
  • They then immediately attempt to write to the Firestore backend. However this continuously fails for up to several minutes (varies between 30sec and 2+ minutes).
  • Eventually the following is logged:
I/Firestore(31596): (24.0.1) [GrpcCallProvider]: Current gRPC connectivity state: CONNECTING
I/Firestore(31596): (24.0.1) [GrpcCallProvider]: Setting the connectivityAttemptTimer
I/Firestore(31596): (24.0.1) [GrpcCallProvider]: Current gRPC connectivity state: READY

after which they can succesfully send data to the backend again.

Here's the entire log of a session I just did. It took 57.818 seconds for it to realize that it was possible to connect:

Apologies for posting this here, but I believe this is primarily an issue with gRPC and not their SDK.

Also, I should mention that this behavior is disastrous in the context of a cloud database. It should always be able to connect immediately when coming out of standby. 😅

Ps. Here's the class that's doing the gRPC logging for posterity: https://github.com/firebase/firebase-android-sdk/blob/ac3276ce7d5f5181b1c419731495eb88a98537af/firebase-firestore/src/main/java/com/google/firebase/firestore/remote/GrpcCallProvider.java

Pps. Here's an old but interesting issue that seems very related: #4028

I'm getting unable to resolve host in android when I'm opening the app from the background in some time.

This might be related to #8850

Closing since we know #8850 was very similar problem and it likely addressed this. The delay before detecting network is good is because the channel is doing retry attempts with exponential backoff. The exponential backoff maxes out at 2 minutes which seems to agree with the observed behavior. If the other fix turns out not to address this, comment and this can be reopened.
