Polygon ID Android SDK + Demo app

What is it?

This native SDK enables developer to use the PolygonID solution.

How to use the SDK

Prerequisite

1. Download and unpack those Maven local repository
2. Add this to your build.gradle or settings.gradle:

    String storageUrl = System.env.FLUTTER_STORAGE_BASE_URL ?: "https://storage.googleapis.com"

    repositories {
        google()
        mavenCentral()
        maven {
            url 'm2'
        }
        maven {
            url "$storageUrl/download.flutter.io"
        }
    }

m2 being the path where you unpacked the download of step 1.

3. Add the SDK dependency:

implementation 'io.github.0xpolygonid.polygonid_android_sdk:release:1.1.0'

Init

The SDK needs to be initialized before being used:

    PolygonIdSdk.init(
        context = context,
        env = EnvEntity(
            blockchain = "polygon",
            network = "mumbai",
            web3Url = "https://polygon-mumbai.infura.io/v3/",
            web3RdpUrl = "wss://polygon-mumbai.infura.io/v3/",
            web3ApiKey = "theApiKey",
            idStateContract = "0x134B1BE34911E39A8397ec6289782989729807a4",
            pushUrl = "https://push-staging.polygonid.com/api/v1"
        )
    )

The env param is optional but you need to set it up at some point via setEnv.

Once initialized, you can use the SDK through his singleton PolygonIdSdk.getInstance()

Under the hood

Flutter

This SDK is calling the Flutter SDK through MethodChannel, that's why each method have a Context param to initialize the get FlutterEngine.

You don't need to install or know anything about Flutter.

More documentation and support could be found in the Flutter SDK project, please refer to it.

Example app

You can find an executable example app in the source with several call to the SDK, which can guide you through your development.
