Running (devnet)

Prerequisites

• Android emulator (Android Studio, IntelliJ IDEA, etc.)
• starknet-devnet-rs

Steps

1. Install starknet-devnet-rs. Since it has yet to be released, you will need to build it manually:

   git clone https://github.com/0xSpaceShard/starknet-devnet-rs.git starknet-devnet-rs
   cd starknet-devnet-rs
   cargo build --release
   export DEVNET_PATH=$(pwd)/target/release/starknet-devnet

2. Run devnet with specific parameters on your host machine:

   $DEVNET_PATH --host 127.0.0.1 --port 5050 --seed 1053545547

3. Run the MainActivity on the emulator.

Running (networks)

Running the demo on a network other than devnet (Mainnet/Testen/Integration) requires some tweaks to be made.

Prerequisites

• Android emulator (Android Studio, IntelliJ IDEA, etc.)
• URL of a Starknet RPC node.
• Account deployed on said network with some funds on it. If you're using Sepolia testnet, you can obtain some funds from the faucet.
• A valid configuration that consists of the data above:
  • DEMO_RPC_URL - RPC node URL
  • DEMO_ACCOUNT_ADDRESS - account address
  • DEMO_ACCOUNT_PRIVATE_KEY - account private key

Steps

1. Set a config with your data. To do so, you can modify build.gradle.kts:

   android {
       ...
       defaultConfig {
           ...
           buildConfigField("String", "DEMO_RPC_URL", "\"http://example-node-url.com/rpc\"")
           buildConfigField("String", "DEMO_ACCOUNT_ADDRESS", "\"0x123456789\"")
           buildConfigField("String", "DEMO_PRIVATE_KEY", "\"0x123\"")
           }
       }
   }

2. Run the MainActivity on the emulator.
