To build the app, you need NodeJs and Apache Cordova. See the instructions on the official website. Android & Ios dependencies are not part of this scope.
As the project is build around the webwallet, the first thing to do is to download the content of the official plenteum webwallet and put the content of the wwwroot directory inside the src directory of this repo (after compiling. See instructions in the upstream repository).
Create a directory named "www", empty.
The next step is to compile with
cordova build
To launch the Android app you will need to launch
cordova run android
With the cordova cli, it is possible to generate signed APKs with the following command
cordova build android --release -- --keystore="../Keys/MobileAppAndroid.jks" --alias=key0 --password=XXXX --storePassword=XXX
where ../Keys/MobileAppAndroid.jks is the path to the keystore and key0 is the key alias
