# 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.

<Note>
  **Supported Frameworks**

  <Tabs>
    <Tab title="Expo / React Native">
      For both Expo or React Native Android development:

      * View the Expo [**setup documentation**](https://docs.expo.dev/get-started/set-up-your-environment/?platform=android\&device=physical\&mode=development-build\&buildEnv=local) (Choose custom development build instead of Expo Go).
    </Tab>

    <Tab title="Kotlin (Native)">
      For Kotlin Android development:

      * Install [Android Studio](https://developer.android.com/studio/install).
    </Tab>

    <Tab title="Flutter">
      For Flutter Android development:

      * View the official Flutter [**setup documentation**](https://docs.flutter.dev/get-started/install/macos/mobile-android#configure-android-development).
    </Tab>
  </Tabs>
</Note>

## 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:

## Install a development wallet app

The [Mobile Wallet Adapter](/get-started/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.

### Mock MWA Wallet

Solana Mobile provides a mock 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 mock wallet features:

* Mobile Wallet Adapter support
* Simulate connection or signing errors

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.
