QRL mobile wallet based on the react native framework

QRL Mobile wallet

This mobile application is based on the react-native framework to provide an Android and iOS implementation of the QRL wallet.

General information

The mobile-wallet apps are still under heavy development. Please be aware that frequent changes will occur to this repository.

Requirements

Common to iOS and Android

• React-Native (https://facebook.github.io/react-native/)
• CMake (https://cmake.org/)

iOS specific

• XCode
• Cocoapods (https://cocoapods.org/)

Android specific

• Android Studio (https://developer.android.com/studio/install)
• Gradle (https://gradle.org/): can be handled within Android Studio

How to generate the iOS libraries

To generate the iOS libraries you need to clone the theQRL/qrllib and build the *.a iOS libraries (for the simulator and real device) using Xcode.

git clone https://github.com/theQRL/qrllib
git submodule update --init --recursive
cd qrllib
mkdir build
cd build
cmake -G Xcode ..

These commands will generate a new Xcode project called qrllib.xcodeproj.
Open the Xcode project and build the 4 different libraries (dilithium, kyber, qrllib and shasha) for the iOS simulator and "iOS generic device". You will see all the generated libraries under build/Debug-iphoneos and build/Debug-iphonesimulator directories.

How to generate the Android libraries

To generate the Android libraries you need to load the /android project folder in Android Studio and open the build-gradle file.
Open the "Gradle menu" and double click on "android:app [externalNativeBuildDebug]" under the "Run Configurations" category to start building the libraries.
The generated *.so libraries are located under android/app/build/intermediates/cmake/debug/obj/.

How to update proto files

In case of any change on the proto file, one needs to regenerate the gRPC pods

rm -rf Pods
rm Podfile.lock
pod install

Load the generated libraries to the mobile-wallet app

• Open the mobile-wallet Xcode project (ios/theQRL.xcworkspace)
• Click on the project name (theQRL) and select theQRL under the TARGETS list
• Add all the generated .a libraries to the Linked Frameworks and Libraries section
