Gno Native Kit Gno Native Kit is a framework that allows developers to build and port gno.land (d)apps written in the (d)app's native language. Current Gno (d)apps run on desktop/laptop computers which have Go installed. To run on mobile, the (d)app would need to bundle the Go runtime, which is complicated for most developers. However, Gno Native Kit helps bypass this complexity by using gRPC to make calls to the Gno core API and access the blockchain's realm functions on a remote Gno.land node. These API calls are a programming language-independent wrapper on top of the core supported APIs like gnoclient and crypto/keys . Watch this Gno Native Kit tutorial to easily get started on building and bringing your (d)apps to mobile and desktop. Build instructions Install prerequisites for macOS 13 (If you are on Ubuntu, see the next section to install prerequisites.) Install Xcode. To install the Command Line Developer Tools, in a terminal enter: xcode-select --install After the Developer Tools are installed, we need to make sure it is updated. In System Preferences, click Software Update and update it if needed. To install asdf using brew, follow instructions at https://asdf-vm.com . In short, first install brew following the instructions at https://brew.sh . Then, in a terminal enter: brew install asdf gnu-tar gpg jq If your terminal is zsh, enter: echo -e "\n. $(brew --prefix asdf)/libexec/asdf.sh" >> ${ZDOTDIR:-~}/.zshrc If your terminal is bash, enter: echo -e "\n. \"$(brew --prefix asdf)/libexec/asdf.sh\"" >> ~/.bash_profile Start a new terminal to get the changes to the environment. (optional) To install Android Studio, download and install the latest android-studio-{version}-mac.dmg from https://developer.android.com/studio . (Tested with Jellyfish 2023.3.1 .) Install prerequisites for Ubuntu 20.04, 22.04 and 24.04 To install asdf, follow instructions at https://asdf-vm.com . In short, in a terminal enter: sudo apt install curl git make git clone https://github.com/asdf-vm/asdf.git ~/.asdf echo '. "$HOME/.asdf/asdf.sh"' >> ~/.profile source ~/.profile Start a new terminal to get the changes to the environment. (optional) To install Android Studio, download the latest android-studio-{version}-linux.tar.gz from https://developer.android.com/studio . (Tested with Jellyfish 2023.3.1 .) In a terminal, enter the following with the correct {version}: sudo tar -C /usr/local -xzf android-studio-{version}-linux.tar.gz To launch Android Studio, in a terminal enter: /usr/local/android-studio/bin/studio.sh & Get a copy of the repo git clone https://github.com/gnolang/gnonative cd gnonative Build for Android Set up the Android NDK Launch Android Studio and accept the default startup options. Create a new default project (so that we get the main screen). On the Tools menu, open the SDK Manager. In the "SDK Tools" tab, click "Show Package Details". Expand "NDK (Side by side)" and check "23.1.7779620". Click OK to install and close the SDK Manager. Install the tools with asdf (only need to do once) (If not building for iOS, edit the file .tool-versions and remove the unneeded lines for ruby and cocoapods .) make asdf.install_tools Build the Go code as a library make build.android Start metro cd examples/js/react-native/gnoboard yarn start Connect your Android phone/emulator and bind its port to metro You can either connect an Android phone via USB cable, or launch an emulator device from Android Studio. Real device Connect your device and bind the port to metro: cd examples/js/react-native/gnoboard make android.reverse_tcp Emulator device You can either run Android Studio and open the Android project in examples/js/react-native/gnoboard/android . If you prefer the CLI option: android-studio ./android Once done, bind the port to metro: make android.reverse_tcp Build with Android Studio Open Android Studio and open the current Android project if it's not already done. Select the right device in the device list. Open the Run menu, and select Run app .
