Getting Started

Initialize FCL and add Blocto as a wallet provider

In this guide we will show you prerequisite for Blocto Flow SDK.

A sample app is available at: https://github.com/blocto/fcl-android/tree/main/fcl-sample

Installation

Add the dependency below to your module's build.gradle file

dependencies {
    implementation "com.portto.fcl:$fclVersion"
}

Initialization

Add FCL content provider to AndroidManifest.xml.

<application>
<provider
            android:authorities="com.portto.fcl.context"
            android:name="com.portto.fcl.lifecycle.FCLContentProvider"
            android:exported="false"/>
</application>

To initialize FCL, call Fcl.init().

Fcl.init(
    env = Network.TESTNET,
    appDetail = AppDetail("My first dApp"),
    supportedWallets = walletProviderList
)

FCL requires some essential information for initialization:

• env: The network on which the app was built. i.e. Network.TESTNET or Network.MAINNET

• appDetail (optional): The information of the app.

• supportedWallets: A list of wallet providers supported by the app.

Wallet Provider

A wallet provider is the instance of a Flow wallet. The following is an example of adding Blocto as a wallet provider.

val walletProviderList = listOf(Blocto.getInstance(YOUR_BLOCTO_APP_ID))

Fcl.init(
    env = Network.TESTNET,
    appDetail = AppDetail(),
    supportedWallets = walletProviderList
)

To obtain a Blocto App ID, please refer to the instructions.

If you initialize FCL with Network.TESTNET, FCL utilizes Blocto testing App ID; Likewise, if you initialize FCL with Network.MAINNET, FCL utilizes Blocto production App ID.
