Manifest Configuration:

<application>
    <!-- Particle Network Configuration Start -->
    <!-- Web Activity -->
    <activity
        android:name="com.particle.network.controller.WebActivity"
        android:exported="true"
        android:launchMode="singleTask"
        android:configChanges="orientation|keyboardHidden|screenSize"
        android:theme="@style/ThemeAuthWeb">
        <intent-filter>
            <data android:scheme="pn${PN_APP_ID}" />
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
        </intent-filter>
    </activity>
    
    <!-- Redirect Activity -->
    <activity
        android:name="com.connect.common.controller.RedirectActivity"
        android:exported="true"
        android:launchMode="singleTask"
        android:configChanges="orientation|keyboardHidden|screenSize"
        android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen">
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="connect${PN_APP_ID}" />
        </intent-filter>
    </activity>
​
    <!-- Metadata Configuration -->
    <meta-data
        android:name="particle.network.project_id"
        android:value="${PN_PROJECT_ID}" />
    <meta-data
        android:name="particle.network.project_client_key"
        android:value="${PN_PROJECT_CLIENT_KEY}" />
    <meta-data
        android:name="particle.network.app_id"
        android:value="${PN_APP_ID}" />
    <!-- Particle Network Configuration End -->
</application>

1. Gradle Properties: In your app/build.gradle.kts file, add the following placeholders:

   android {
       defaultConfig {
           minSdk = 23
           targetSdk = pnTargetSdk
           //...
       }
       // ...
       defaultConfig {
           manifestPlaceholders["PN_PROJECT_ID"] = "Replace-With-Your-Project-ID"
           manifestPlaceholders["PN_PROJECT_CLIENT_KEY"] = "Replace-With-Your-Project-Client-Key"
           manifestPlaceholders["PN_APP_ID"] = "Replace-With-Your-App-ID"
       }
       // ...
   }

   You can obtain these values from Particle Network Dashboard.

Initialization

Initialize ParticleConnect in your application with Wallet Connect support:

val dAppMetadata = DAppMetadata(
    = "",
   name = "Particle Connect",
   icon = "https://connect.particle.network/icons/512.png",
   url = "https://particle.network",
   description = "Particle Connect is a decentralized wallet connection protocol that makes it easy for users to connect their wallets to your DApp.",
   )
​
ParticleConnect.init(this.application, Env.PRODUCTION, Ethereum, dAppMetadata) {
    listOf(
        MetaMaskConnectAdapter(),
        RainbowConnectAdapter(),
        TrustConnectAdapter(),
        WalletConnectAdapter(),
        ImTokenConnectAdapter(),
        BitKeepConnectAdapter()
    )
}

Login

Use the following code snippet to perform login with Wallet Connect:

val walletName = MobileWCWalletName.
val metaMaskConnectAdapter = ParticleConnect.getAdapters().first {
     it.name == walletName.name 
 }
val config = null // ParticleConnectConfig only used for ParticleConnectAdapter, other adapter can be null
metaMaskConnectAdapter.connect(config, object : ConnectCallback {
    override fun onConnected(account: Account) {
        //connected wallet's  address, it is 0x address
        val address = account.publicAddress
    }

    override fun onError(error: ConnectError) {
        //process error
    }
})

Conclusion

This concludes the Wallet Connect integration guide for ParticleConnect in your Android application. Utilize this functionality to seamlessly connect decentralized wallets to your DApp.
