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

Use the GUI of Android studio to create a new virtual devide. As of 23/06/2022 we are using a Pixel 5 as template and System image R API level 30 Android 11.0

If using a phone, start the USB debugging mode.

Open or create `robosats/mobile/android/local.properties`:

- Add `sdk.dir = /home/<YOUR_USERNAME>/Android/Sdk`

You can check your SDK location on the GUI of Android studio: `Tools > SDK Manager`
Make sure you have NDK installed : `Tools > SDK Manager > SDK Tools > NDK (Side by Side)`

## Launch app builder and

Point a terminal to `/robosats/mobile/`

```
npm start
```

on another temrinal also in `/robosats/mobile/`

```
npx react-native run-android
```
