BitizenConnectKotlin

library to use BitizenConnect with Kotlin or Java

添加SDK依赖

将@jitpack添加到gradle文件中

repositories {
 ...
 maven { url 'https://jitpack.io' }
}

添加sdk依赖

从https://jitpack.io/#BitizenWallet/BitizenConnectKotlin查找最新版本号

dependencies {
 implementation 'com.github.BitizenWallet:BitizenConnectKotlin:40900783c1'
}

使用方式

初始化BitizenConnectApi

val connection = BitizenConnectApi(object :BitizenConnectDelegate{
        override fun didConnect(chainId: Int?, accounts: String?) {
            TODO("连接成功，返回chain id 和钱包地址")
        }

        override fun didDisconnect() {
            TODO("连接断开")
        }

        override fun failedToConnect() {
            TODO("连接失败")
        }

    })

连接钱包

需要配置deeplink，用于Bitizen App处理完事务后，返回当前App

<intent-filter >
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <!-- Accepts URIs that begin with "example://gizmos” -->
    <data android:scheme="bitizendapp"
        android:host="wc" />
</intent-filter>

调用连接钱包API

connection.connect(
        context = requireContext(),
        dappName = "Example App",
        dappDescription = "bitizenconnect_android_example",
        dappUrl = "https://example.com",
        icons = listOf("用于Bitizen App展示dapp的图片"),
        callbackUrl = "bitizendapp://wc", // 设置返回当前App的deeplink
    )

签名

SDK 支持 eth sign 、personal sign 和 signTypedData

eth_sign 是危险操作，会导致资金丢失，Bitizen Wallet 已经把 eth_sign 封禁

connection.personalSign(
            requireContext(),
            message = "0xff",
            account = "钱包地址"
        ) {resp ->
            // 回调方式位于子线程，务必切换到UI线程进行UI展示
            uiScope.launch {    
                binding.txRespData.text = it.result.toString()
            }
        }

交易

connection.ethSendTransaction(
        requireContext(),
        Transaction(
            from = binding.txAddress.text.toString(),
            to = binding.txAddress.text.toString(),
            nonce = null,
            gasPrice = null,
            gasLimit = null,
            value = "0xff",
            data = "0x",
        )
    ) {
        uiScope.launch {
            binding.txRespData.text = it.result.toString()
        }
    }
