```
brew install node
brew install watchman
```

## Create Emulator (or connect Android phone and install adb)

Use the GUI of Android studio to create a new virtual devide, make sure you add enought internal storage (>= 2 GB).
Pixel 5 as template and System image R API level 30 Android 11.0 is the one we use on development.

## Run app

- Point a terminal to `nostros`
- Install yarn packages

```
yarn install
```

- Make sure your device is running, if you are using a physical one remember to run on a terminal `adb reverse tcp:8081 tcp:8081` so it can connect to Metro.
- Run Metro

```
yarn start
```

Below instructions are for Ubuntu and other related Debian-based distributions. For other flavours, you'll probably just need to change the package manager.

Download and install https://developer.android.com/studio/index.html
Use the local installation in preference to any flatpak release provided through your distro, this will save you issues with your environment later on!

```
sudo npm install -g react-native-cli
sudo npm install -g yarn
sudo apt install android-sdk-platform-tools
```

Before opening the project in Android Studio, run `yarn install` in the project root folder. Otherwise gradle will complain of missing files in the `react-native` node-modules folder.
