Choosing well
Check Android and target platforms
Confirm Android support if the app or service must run on a Xiaomi, Redmi or POCO phone or tablet. Platform coverage in this category can also include web, Windows, Linux, iOS and macOS.
Match the SDK's target platforms to the software you plan to ship, rather than assuming a library covers every device.
Compare free and paid terms
A free plan is available from tools in this category, while other products use paid or freemium pricing. Check what the free plan includes before building around it.
Published examples include a 14-day trial with Datadog APM, pricing on request for Agora SDKs, and HID SDK from $500 per year.
Match languages and package managers
Compare supported languages with the languages used by your project. Package-manager support can affect setup, updates and how dependencies are shared across builds.
Review code, hosting and offline use
Open-source code is available from tools in this category. Check the source and licence to confirm that the terms fit your software.
A self-hosted option and offline support can change deployment and connectivity requirements, so compare both before selecting an SDK.
