Migration from Helium 3.X to Chartboost Mediation 4.0.0

As part of the Marketing team’s efforts to clearly articulate the use cases and customers we support by being more descriptive with our product branding, Helium is being rebranded as Chartboost Mediation.

Starting in 4.0.0, the Chartboost Mediation brand will be used in place of Helium for new additions. In the coming 4.X releases, the old Helium branding will be deprecated and the new Chartboost Mediation branding will be used to give publishers a smoother transition.

This document exists to specifically address all possible issues that developers might encounter when migrating from Helium 3.X integrations to Chartboost Mediation 4.0.0

Unity SDK Repository 🔗

The Unity SDK repository will be renamed to reflect the new branding.

npm Package & UPM 🔗

As part of Chartboost’s rebranding efforts, Chartboost Mediation 4.0.0 will be using a new npmjs package for the distribution of the Chartboost Mediation Unity SDK.

To update your existing package reference, rename the existing package on your manifest.json file.

• Helium 3.X
• Chartboost Mediation 4.0.0

• "dependencies": {  
      "com.chartboost.helium": "3.3.2"  
   …  
  }
  

• "dependencies": {  
      "com.chartboost.mediation": "4.0.0"

    "com.chartboost.mediation": "4.0.0",
    ...
  },
  "scopedRegistries": [
    {
      "name": "NpmJS",

Public API Changes 🔗

Helium Name 🔗

The HeliumSDK name has been deprecated and replaced by ChartboostMediation.

Unity will produce any warnings whenever deprecated APIs are in use, and provide detailed descriptions of how to remedy such warnings for each scenario.

Here is an example scenario of how to address such issues:

    // This will produce a warning as it has been deprecated
    HeliumSDK.SetUserIdentifier("DEFAULT");

    // New 4.0.0 API
    ChartboostMediation.SetUserIdentifier("DEFAULT");

In most scenarios, a find and replace from HeliumSDK to ChartboostMediation should be enough to fix the warnings. However, namespaces have also been modified, look at the section below for more details.

Namespace 🔗

The Helium namespace has been deleted and removed from most places in the Chartboost Mediation Unity SDK. It is still available for most deprecated classes, but it is highly recommended to transition to the new Chartboost namespace. All rebranded and refactored APIs are available under the Chartboost namespace. All rebranded and refactored APIs are available under the Chartboost namespace.

The prior code would look something like this:

    using Helium;

    // This will produce a warning as it has been deprecated
    HeliumSDK.SetUserIdentifier("DEFAULT");

The new APIs will utilize the Chartboost namespace as follows:

    using Chartboost;

    // New 4.0.0 API
    ChartboostMediation.SetUserIdentifier("DEFAULT");

Editor Classes 🔗

All Chartboost Mediation Unity SDK classes have been rebranded. Obsolete APIs are still available but it is highly recommended to transition to the new existing APIs.

Delegates 🔗
