Build and Run the App

Build and Run the App

Build

For the app environment, we use the package manager yarn. You can install it via npm

npm install --global yarn
yarn --version #check version

In the cloned project (refer to Build Documentation) root, we can now install all the needed dependencies for the app by running the command

yarn

This will also download the expo framework which we use to deploy and run the app.

• Make sure that you have no previous installation of node_modules in your root directory from other tools like npm before running yarn. This might interfere with yarn.

Install the App on Your Phone

You can either execute the app on your personal phone or an emulator. The following steps will require access to a development build. Ask one of the friendly developers of this repository :).

Get the Development Build

To download a development build, sign into your expo account here. Click on the amos-health-ai-framework organization.

Now, click on the AiLixir project.

On the left side, navigate to Builds. Click on the topmost build. Now click on Install.

• Scan the showing QR-code with your device, et voilà, it will install the development build on your device.
• Alternatively, if you want to use an emulator, click on the three dots to the right and download the build on your computer. Once you have the emulator running, drag and drop the downloaded build file on your emulator.

Emulator

You can use Android Studio to set up an emulator. Follow the steps detailed under Set up Android Studio on the official expo documentation.

Run the App

Once you have installed the dependencies and the development build of the app, you are ready to run it! :) If you haven't already In your terminal, execute

yarn start

It should say Using development build, otherwise press 's'.

Now on your device, scan the QR code. If you are using an emulator you can instead press 'a'.

Et voilà, this should run the app on the chosen device.
