Getting below error when generating prekeys.
I am trying to achieve end-to-end encryption in a chat window.

@rubenquadros can you provide more information. For example, a code snippet showing how to replicate the issue.

[rubenquadros]

@sriram2093 I am generating identity keys, prekeys and registration id as below

class SignalProtocolManagerImpl : SignalProtocolManager {

    override fun initProtocol(userId: String) {
        val identityPairKey = KeyHelper.generateIdentityKeyPair()
        val registrationId = KeyHelper.generateRegistrationId(false)
        val preKeys = KeyHelper.generatePreKeys(0, 200)
        val signedPreKey = KeyHelper.generateSignedPreKey(identityPairKey, registrationId)

        FirebaseHelper.sendSignalBundle(
            identityPairKey,
            registrationId,
            preKeys,
            signedPreKey,
            userId
        )
    }

    override fun generatePreKeys() {
        //do nothing
    }
}

I am calling this method from my activity after the user has successfully logged in for the first time

private fun updateLoginResult(loginRecord: ServerRecord) {
        ApplicationUtility.stopProgress(binding.loginPb, this)
        when (loginRecord) {
            is Success -> {
                ApplicationUtility.showToast(this, getString(R.string.all_sign_in))
                updateProfile(FirebaseAuth.getInstance().currentUser!!.uid)
            }
            NewUser -> {
                ApplicationUtility.showToast(this, getString(R.string.all_sign_in_first_time))
                val userId = FirebaseAuth.getInstance().currentUser!!.uid
                signalManager.initProtocol(userId)
                getGoogleProfile(userId)
            }
            AuthFail -> {
                ApplicationUtility.showSnack(getString(R.string.all_auth_fail), binding.loginParent, ok)
            }
            else -> {
                ApplicationUtility.showSnack(genericError, binding.loginParent, ok)
            }
        }
    }

[atyanands]

getting same error, did you find any solution.?? @rubenquadros

[rubenquadros]

@atyanands I haven't found anything. Please let me know if you have got anything.
@alan-signal @moxie0 Can you please help?
Thanks in advance.

[atyanands]

@rubenquadros yes it was because of protobuf library version conflict.
use force version in android config

configurations { all { resolutionStrategy { force group: 'com.google.protobuf', name: 'protobuf-javalite', version: '3.10.0' } } }

[rubenquadros]

@atyanands I am not getting any error after forcing the protobuf version to 3.10.0.
Thanks for your help!
