Get started with the XMTP Android SDK

// 1. Create an EOA or SCW signer.
// Details depend on your app's wallet implementation.
class EOAWallet : SigningKey {
    override val publicIdentity: PublicIdentity
        get() = PublicIdentity(IdentityKind.ETHEREUM, key.publicAddress)
    override val type: SignerType
        get() = SignerType.EOA
    override suspend fun sign(message: String): SignedData {
        return SignedData(key.sign(message = message))
    }
}
 
// 2. Create the XMTP client
val client = Client.create(
    account = SigningKey,
    options = ClientOptions(
        ClientOptions.Api(XMTPEnvironment.PRODUCTION, true),
        appContext = ApplicationContext(),
        dbEncryptionKey = keyBytes // 32 bytes
    )
)
 
// 3. Start conversations
val group = client.conversations.newGroup(inboxIds = listOf(bo.inboxId, caro.inboxId))
val groupWithMeta = client.conversations.newGroup(
    inboxIds = listOf(bo.inboxId, caro.inboxId),
    permissionLevel = GroupPermissionPreconfiguration.ALL_MEMBERS,
    name = "The Group Name",
    imageUrl = "www.groupImage.com",
    description = "The description of the group"
)
 
// 4. Send messages
val dm = client.conversations.findOrCreateDm(recipientInboxId)
dm.send(text = "Hello world")
group.send(text = "Hello everyone")
 
// 5. List, stream, and sync
// List existing conversations
val conversations = client.conversations.list()
val filteredConversations = client.conversations.list(consentState = ConsentState.ALLOWED)
// Stream all new conversations and new messages from allowed conversations
client.conversations.streamAllMessages(consentStates = listOf(ConsentState.ALLOWED)).collect {
    // Received a message
}
// Sync all new welcomes, preference updates, conversations,
// and messages from allowed conversations 
client.conversations.syncAll(consentStates = ConsentState.ALLOWED)
