Kotlin Quickstart

The quickest way to start building Solana Kotlin dApps is to build off the Solana Jetpack Compose Scaffold.

Solana Jetpack Compose Scaffold

The scaffold app serves as both a starting implementation and an example reference of how to use the core Kotlin SDKs, like web3-core, rpc-core, and Mobile Wallet Adapter.

It includes:

• Core Solana kotlin libraries
• Pre-built Compose UI components,
• Code examples of transaction building and RPC requests.

Prerequisites

Follow the prerequisite setup guide to set up Android Studio, your Android Device/Emulator and install a MWA-compatible wallet, like fakewallet.

Install the Jetpack Compose Scaffold

Clone the repo

The scaffold app is open source and can be fetched from Github.

git clone https://github.com/solana-mobile/solana-kotlin-compose-scaffold.git

Open the project in Android Studio

In Android Studio, open the project with File > Open > SolanaKotlinComposeScaffold/build.gradle.kts

Build and run

Ensure you have connected an Android emulator or device and it is detected by Android Studio. If not, follow this guide to setup your emulator/device.

In the top bar of Android Studio, select "app" as the configuration and your emulator/device, then click run.

If successful, the scaffold app will launch on your emulator/device.

Connect with a locally installed wallet app to start interacting with the Solana network! 🎉
