Third-party mobile SDKs are the utility belt of mobile developers, allowing them to extend the functionality of their apps with minimal effort.

But while implementing a third-party SDK might take a matter of minutes for the seasoned mobile developer, deciding which mobile SDKs to implement is not an act of arbitrary selection. A developer trying to keep code lean should carefully consider how an additional mobile library could affect app performance, asking questions like:

• What vendors do we currently use that offer a mobile SDK?
• What sort of impact will third-party mobile SDKs have on app complexity?
• What sort of resources are required for this app to function properly?

Take a look at the top 10 third-party mobile SDKs in use on iOS (3 analytics SDKs, 3 advertising SDKs, and 4 other), with descriptions and requirements for both Android and iOS.

Note: Thanks to Kevin Leong and the AppSight team for providing the statistics here. All statistics refer to the top third-party mobile SDKs for iOS apps.

Validating Your Third-Party Mobile SDKs

No matter the OS (Android or iOS), implementing third-party mobile SDKs such as the ones listed above can greatly extend the functionality of your app, providing additional insights into mobile app behavior and improving the overall user experience.

But while deploying new third-party mobile SDKs is a relatively simple procedure, continuously monitoring and testing mobile SDK performance is a challenge many app stakeholders face. Thousands of potential use cases under a variety of app conditions make manual testing a burden on resources and drastically slow down release cycles.

Adopting a mobile SDK testing platform like AppAssurance™ allows you to test SDK performance over time with a customized library of test use cases. With an easy step-by-step journey builder, you can build a library of app journeys that validate SDK data collection against predefined rules.

Validate your mobile SDKs with a free evaluation of your mobile application.
