RWallet

Introduction

This is a multi-cryptocurrency wallet application. Supports both english and spanish.

Prerequisite

To run on Android

In order to run this App in Android Simulator, Android Studio needs to be installed. Please refer to https://developer.android.com/studio
Open Android Studio, create a device via Tools > AVD Manager > Create Virtual Device. After downloading required dependencies, start the device by clicking on Play icon.
Now we are testing if you can invoke adb in terminial. This is for running rWallet Android App on Android virtual device.
1. Since we already have Android Studio installed we can add platform-tools to path
```
echo 'export ANDROID_HOME=/Users/$USER/Library/Android/sdk' >> ~/.bash_profile
echo 'export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools' >> ~/.bash_profile
```
2. Then, refresh bash profile by source ~/.bash_profile
3. Start using adb with adb devices
4. If you have a virtual device running, it should show
```
List of devices attached
emulator-5554	device
```

To run on iOS Devices

XCode needs to be installed. iOS simulator will be install along with XCode.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

The first three steps are needed for both Android and iOS devices.

npm install to install dependencies

Create an environment variable file named .env in the root directory

# Parse server configuration
# Dogfood Server URL http://130.211.12.3/parse
# Devbox Server URL for Android Simulator http://10.0.2.2:1338/parse
# Devbox Server URL for iOS Simulator http://<YOUR_IP_ADDRESS>:1338/parse
PARSE_SERVER_URL=

If .env file is changed, manually edit the file importing react-native-dotenv by either adding an empty line or whitespace will work.

npm run android or npm run ios. The script will first start server daemon in a separate terminal window, the same effect as npm run start. You should see console output like below.

Looking for JS files in
  /Users/mikasa/Documents/repos/rwallet 

Loading dependency graph, done.

For Android, npm run android will start the app in your physical device or Android virtual device. You need to check what device are available by running adb devices in terminal. To test the app in a physical Android device, you need to make sure Developer Options -> Enable Debugging via USB is turned on for that device. Note: If you encounter an error like below then you need to create a local.properties file under ./android and add one line sdk.dir = /Users/<username>/Library/Android/sdk in it.
```
SDK location not found. Define location with an ANDROID_SDK_ROOT environment variable or by setting the sdk.dir path in your project's local properties file at '/Users/<usernmae>/Documents/repos/rwallet/android/local.properties'.
```
For iOS device, npm run ios will start the App in iOS physical or virtual device.

Hot reload code change - Press Command + m on virtual device and select Enable Hot Reloading to hot reload file changes.

Fastlane

Set up Fastlane

Homebrew	Installer Script	Rubygems
macOS	macOS	macOS or Linux with Ruby 2.0.0 or above
`brew cask install fastlane`	Download the zip file. Then double click on the `install` script (or run it in a terminal window).	`sudo gem install fastlane -NV`

Build on iOS

Make sure you have the latest version of the Xcode command line tools installed:
```
xcode-select --install
```
Set up fastlane match by running fastlane match init. match is the alias for the sync_code_signing action. It creates all required certificates & provisioning profiles and stores them in a separate git repository.
Gernerate certificates by fastlane match appstore
Once match is set, run fastlane ios beta version:<version_number> build:<build_number> to push to TestFlight. For example, fastlane ios beta version:0.8.1 build:3 (build parameter can be omitted for auto-increment)

build on Android

Make sure you have Android Studio installed, so that it is easy to sync the gradle build config.
To build the APK, run fastlane android build_apk version:<version_number> code:<version_code>

Devleopment

Remote Debugging

Remote Debugging on iOS Simulator

Run npm run ios to start the app in Simulator.
Wait for the build

Remote Debugging on Android Devices

Step 1: Discover your Android device

Open the Developer Options screen on your Android. See Configure On-Device Developer Options.
Select Enable USB Debugging
On your development machine, open Chrome.
Open DevTools.
In DevTools, click the Main Menu Main Menu then select More tools > Remote devices.
In DevTools, open the Settings tab.
Make sure that the Discover USB devices checkbox is enabled.
Connect your Android device directly to your development machine using a USB cable. The first time you do this, you usually see that DevTools has detected an unknown device. If you see a green dot and the text Connected below the model name of your Android device, then DevTools has successfully established the connection to your device.
If your device is showing up as Unknown, accept the Allow USB Debugging permission prompt on your Android device.

Step 2: Debug content on your Android device from your development machine TODO: How to debug android app with Mac OS is to be added

Debugging

Mac OS Dev environment
- In Android Simulator, press Command + M to start remote debugging
- In iOS Simulation, press Command + D to start remote debugging
