OMH (Open Mobile Hub) - Core

Overview

OMH is an Android SDK, available as open-source, that simplifies the process of swapping services such as Maps & Location, Sign-in, Storage, and more, for both Android GMS and Non-GMS devices.

It aims at creating low coupled, extensible SDK reducing the code boilerplate of switching between GMS, Non-GMS, or any other service, and also provides a custom full open source alternative services switching automatically according to your configuration in the Gradle plugin giving the right outputs without overloading your APK with unnecessary libraries.

OMH - Core

The OMH Core is a Gradle plugin that allows developers to configure, enable and set-up the OMH SDK in their projects.This plugin automatically implements the necessary dependencies and enable the custom-build variants to allow you compile the different builds to use the defined providers.

Installation

Go to your app build.gradle file and add the following:

plugins {
    ...
    id 'omh-core'
}

...

omhConfig {
    bundle('worldwide') {
        it.auth {
            addGmsService 'com.omh.android:auth-api-gms:1.0-SNAPSHOT'
            addNonGmsService 'com.omh.android:auth-api-non-gms:1.0-SNAPSHOT'
        }
    }

    bundle('gmsStore') {
        it.auth {
            addGmsService 'com.omh.android:auth-api-gms:1.0-SNAPSHOT'
        }
    }

    bundle('nonGmsStore') {
        it.auth {
            addNonGmsService 'com.omh.android:auth-api-non-gms:1.0-SNAPSHOT'
        }
    }
}

Usage

Step 1: Create an instance of OmhAuthClient

private val omhAuthProvider = OmhAuthProvider.Builder()
    .addGmsPath(BuildConfig.AUTH_GMS_PATH)
    .addNonGmsPath(BuildConfig.AUTH_NON_GMS_PATH)
    .build()        

private val omhAuthClient = omhAuthProvider.provideAuthClient(
    scopes = listOf("openid", "email", "profile"),
    clientId = "YOUR_CLIENT_ID",
    context = applicationContext
)

Step 2: Start using some functions

In you sample app, perform the authentication

private fun startLogin() {
    val loginIntent = omhAuthClient.getLoginIntent()
    loginLauncher.launch(loginIntent)
}

If the authentication is successful, then navigate to your desired screen

private val loginLauncher: ActivityResultLauncher<Intent> =
    registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->
        try {
            omhAuthClient.getAccountFromIntent(result.data)
            navigateToLogIn()
        }  catch (exception: OmhAuthException) {
            val errorMessage = OmhAuthStatusCodes.getStatusCodeString(404)
        }
    }
