Maker Starter App

Getting Started

App Setup

1. First add your environment variables. See the installing section below for more detail on how to do so.
   1. You will need a Mapbox API key to show the map for Hotspot onboarding.
   2. You will need a Google API key for address and location search.
2. Rename your application using React Native Rename. You will want to pass in the custom bundle identifier for Android and also change it manually for iOS.
3. Update your theme colors in theme.ts. The theme controls the look of the application.
4. Add your Hotspot and Antenna data in the makers folder. See the Makers README for more detail.
5. You will need to update your App Scheme for any deep linking. There are guides for both iOS and Android.
6. The basics of the Helium React Native SDK and Helium Blockchain API have been integrated into this starter app. Review the docs to learn more.

React Native Dev Setup

If you have already set up react native on your machine, skip to the installing section.

React Native dependencies

You will need Node, Watchman, Yarn, the React Native command line interface, Android Studio, and Xcode.

While you can use any editor of your choice to develop your app, you will need to install Xcode and Android Studio in order to set up the necessary tooling to build your React Native app for iOS and Android.

A good free editor is Visual Studio Code.

Node, Watchman, Yarn

We recommend installing Node, Yarn, and Watchman using Homebrew. Run the following commands in a Terminal after installing Homebrew:

brew install node
brew install watchman
brew install yarn

If you have already installed Node on your system, make sure it is up to date with the LTS version.

Watchman is a tool by Facebook for watching changes in the filesystem. It is highly recommended you install it for better performance.

The React Native CLI

Node comes with npm, which lets you install the React Native command line interface.

Run the following command in a Terminal:

npm install -g react-native-cli

If you get an error like Cannot find module 'npmlog', try installing npm directly:

curl -0 -L https://npmjs.org/install.sh | sudo sh.

Xcode

The easiest way to install Xcode is via the Mac App Store. Installing Xcode will also install the iOS Simulator and all the necessary tools to build your iOS app.

If you have already installed Xcode on your system, make sure it is up to date.

Command Line Tools

You will also need to install the Xcode Command Line Tools. Open Xcode, then choose "Preferences..." from the Xcode menu. Go to the Locations panel and install the tools by selecting the most recent version in the Command Line Tools dropdown.

Java Development Kit

React Native requires the Java SE Development Kit (JDK). Download and install JDK 8 if needed.

Android development environment

Setting up your development environment can be somewhat tedious if you're new to Android development. If you're already familiar with Android development, there are a few things you may need to configure. In either case, please make sure to carefully follow the next few steps.

1. Install Android Studio

Download and install Android Studio. Choose a "Custom" setup when prompted to select an installation type. Make sure the boxes next to all of the following are checked:

• Android SDK
• Android SDK Platform
• Performance (Intel ® HAXM)
• Android Virtual Device

Then, click "Next" to install all of these components.

If the checkboxes are grayed out, you will have a chance to install these components later on. Once setup has finalized and you're presented with the Welcome screen, proceed to the next step.

2. Install the Android SDK

Android Studio installs the latest Android SDK by default. Building a React Native app with native code, however, requires the Android 28 SDK in particular. Additional Android SDKs can be installed through the SDK Manager in Android Studio.

The SDK Manager can be accessed from the "Welcome to Android Studio" screen. Click on "Configure", then select "SDK Manager".

Select the "SDK Platforms" tab from within the SDK Manager, then check the box next to "Show Package Details" in the bottom right corner. Look for and expand the Android 28 entry, then make sure the following items are all checked:

• Google APIs
• Android SDK Platform 28
• Intel x86 Atom_64 System Image
• Google APIs Intel x86 Atom_64 System Image

Next, select the "SDK Tools" tab and check the box next to "Show Package Details" here as well. Look for and expand the "Android SDK Build-Tools" entry, then make sure that 30-rc1, 29.0.3, and 28.0.3 are selected.

Finally, click "Apply" to download and install the Android SDK and related build tools.

3. Configure the ANDROID_HOME environment variable

The React Native tools require some environment variables to be set up in order to build apps with native code.

Add the following lines to your $HOME/.bash_profile config file:

export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools

Installing

Environment Variables

1. Copy the file .env.sample and rename it to .env.
2. Once renamed update the values within the file.
3. In order for maps to load you will need to create your own Mapbox access token.

Dependencies

Install 3rd party dependencies

yarn install

You also need cocoapods for iOS

sudo gem install cocoapods

Then install the pods for iOS (Not needed for Android)

yarn pod-install

If the app is not working you may want to clean your workspace and then follow the running the app section below

yarn clean-install
yarn clean-start

Running The App

iOS

The fastest way to run the app is on the iOS simulator. Just type:

yarn ios

You can also open the Illios.xcworkspace file in the /ios folder using xcode and run the app on your device or any other simulator.

Android

Similar to iOS, run

yarn android

You can also open the Android project in Android Studio by selecting open an existing project and selecting the /android folder.
