Development Setup

This section covers the steps to:

• Set up your local environment for Android development.
• Configure a device or emulator for building apps for the dApp Store.
• Install an MWA-compliant wallet app for development purposes.

Set up Android development environment

To build apps for the dApp Store, you need to setup your environment for Android development.

Supported Frameworks

Expo / React Native

For both Expo or React Native Android development:

• View the Expo setup documentation (Choose custom development build instead of Expo Go).

Kotlin (Native)

For Kotlin Android development:

• Install Android Studio.

Flutter

For Flutter Android development:

• View the official Flutter setup documentation.

Setup Device/Emulator

You can test your app during development on any Android device or emulator. A Solana Mobile device is not required for dApp Store development—testing on a standard Android device is typically sufficient.

For detailed device setup instructions, refer to Android's official documentation:

• Setting up a physical device
• Configuring the Android Emulator

Install a development wallet app

The Mobile Wallet Adapter (MWA) library allows your app to connect and interact with compatible wallet apps on your device.

Install an MWA-compatible wallet app to test your app's Mobile Wallet Adapter integration.

Fake Wallet

Solana Mobile provides a 'fake' development wallet for you to test your app with and get a feel of what Seed Vault Wallet interactions on the Seeker will look like.

The fake wallet features:

• Mobile Wallet Adapter support
• Simulate connection or signing errors
• QR Code Scanning for MWA Remote Connections

It is intended for development purposes only, so it does not store a persistent keypair and the wallet is reset each time the app is exited.

Installation steps

1. Clone the Mobile Wallet Adapter repo, containing the fakewallet app from the github repository

git clone https://github.com/solana-mobile/mobile-wallet-adapter.git

2. In Android Studio, Open project > Navigate to the cloned directory > Select mobile-wallet-adapter/android/build.gradle

3. After Android Studio finishes loading the project, select fakewallet in the build/run configuration dropdown in the top right

4. After it builds successfully, you should see the app on your connected Android device or emulator.

Other MWA-compliant wallet apps

You can also install and test with these popular MWA-compatible wallet apps:

• Phantom
• Solflare
