Describe the bug
Error(throwable=com.walletconnect.android.internal.common.exception.NoRelayConnectionException: No connection available)

SDK Version

• Client: Kotlin
• Version 2.1.0

To Reproduce

In the Application class

override fun onCreate() {
super.onCreate()

    val projectId = "xxx"
    val relayUrl = "relay.walletconnect.com"
    val serverUrl = "wss://$relayUrl?projectId=$projectId"
    val connectionType = ConnectionType.AUTOMATIC
    val appMetaData = Core.Model.AppMetaData(
        name = "Buidl Player",
        description = "Watch buidl videos with this app",
        url = "xxx",
        icons = listOf("xxx"),
        redirect = "kotlin-dapp-wc:/request"
    )

    CoreClient.initialize(
        relayServerUrl = serverUrl,
        connectionType = connectionType,
        application = this,
        metaData = appMetaData
    )

    val init = Sign.Params.Init(CoreClient)
    SignClient.initialize(init) { error -> Log.d("Application", "onCreate: $error") }
}

In a fragment

private fun connectToWallet() {
    val dappDelegate = object : SignClient.DappDelegate {
        override fun onSessionApproved(approvedSession: Sign.Model.ApprovedSession) {
            // Triggered when Dapp receives the session approval from wallet
            Log.d("TAG", "onSessionApproved: $approvedSession")
        }

        override fun onSessionRejected(rejectedSession: Sign.Model.RejectedSession) {
            // Triggered when Dapp receives the session rejection from wallet
            Log.d("TAG", "onSessionRejected: $rejectedSession")
        }

        override fun onSessionUpdate(updatedSession: Sign.Model.UpdatedSession) = Unit
        override fun onSessionExtend(session: Sign.Model.Session) = Unit

        override fun onError(error: Sign.Model.Error) {
            Log.d("TAG", "onError: $error")
        }
    }

    SignClient.setDappDelegate(dappDelegate)

    val namespace = "eip155"
    val chains = listOf("eip155:1")
    val methods = listOf(
        "eth_sendTransaction",
        "personal_sign",
        "eth_sign",
        "eth_signTypedData"
    )
    val events = listOf("chainChanged", "accountChanged")
    val namespaces =
        mapOf(namespace to Sign.Model.Namespace.Proposal(chains, methods, events, null))
    val pairing = CoreClient.Pairing.create() ?: return
    val connectParams = Sign.Params.Connect(namespaces, pairing)

    SignClient.connect(connectParams, onSuccess = {
        Log.d("TAG", "connectToWallet: success")
    }, onError = { error ->
        Log.d("TAG", "connectToWallet: $error")
    })
}

Hey @KayCm and @devarogundade, what version of android-core are you using?

[devarogundade]

Version 1.3.0

[KayCm]

Hey @KayCm and @devarogundade, what version of android-core are you using?

implementation("com.walletconnect:auth:1.1.0")
implementation("com.walletconnect:android-core:1.3.0")
implementation("com.walletconnect:sign:2.1.0")

all the newest

[jakubuid]

I cannot reproduce your issue.

Could you please provide the exact user flow steps that you did before getting this error?

Also, please make sure that your app has either a WiFi or cellular Internet connection.

[devarogundade]

Ok on it

D/TAG: connectToWallet: success Connect(namespaces={eip155=Proposal(chains=[eip155:1], methods=[eth_sendTransaction, personal_sign, eth_sign, eth_signTypedData], events=[chainChanged, accountChanged], extensions=null)}, pairing=Pairing(topic=6c2492e30a13a32379a73ed9efa48bf2386f4c8826c6f3edf4d136d921687bc0, expiry=1668081152, peerAppMetaData=null, relayProtocol=irn, relayData=null, uri=wc:6c2492e30a13a32379a73ed9efa48bf2386f4c8826c6f3edf4d136d921687bc0@2?relay-protocol=irn&symKey=eb163fe4003768b216ccbd70d5d140215ceb9d2134752ad7513bba0d48769084, isActive=false, registeredMethods=wc_sessionPropose,wc_sessionSettle,wc_sessionRequest,wc_sessionEvent,wc_sessionDelete,wc_sessionExtend,wc_sessionPing,wc_sessionUpdate))

That's all the place is I have used the SDK,
When I click on the connect wallet before is was
"Error(throwable=com.walletconnect.android.internal.common.exception.NoRelayConnectionException: No connection available"
but now its the log message above and no wallet connection is initialted

[jakubuid]

When the onSuccess callback is triggered from the connect method, it means that the session proposal was being sent successfully to the wallet.

As I can see, you print your connectParams inside the onSuccess callback.

Now you should share with your wallet a pairing.uri as a QR code or deeplink and call the pair method on the wallet side.

[KayCm]

in official demo
when i use the deeplink open the wallet(tokenpocket)
the log will show this.
D/WalletConnectV2: OnConnectionClosing(shutdownReason=ShutdownReason(code=1000, reason=))
D/WalletConnectV2: OnConnectionClosed(shutdownReason=ShutdownReason(code=1000, reason=))

[jakubuid]

Automatic connection mode works in the way that the connection is closed when the wallet hits the background and and is open again when the wallet if foregrounded.
@KayCm
What's the problem that you're trying to solve?

[KayCm]

i think maybe the tokenpocket not support the v2. when i use the v1 it`s work well.
thanks for reply.

[NilayTheAndroidGuy]

@devarogundade I am also getting "com.walletconnect.android.internal.common.exception.NoRelayConnectionException: No connection available". How did you overcome this to success?

p.s.: I have a very similar code implementation to you. Let me know if you changed anything from your above-mentioned code.
