TUIKit Integration

Differences Between the Basic Edition and the Enhanced Edition

  • SDK added the Enhanced Edition from SDK 5.4. The original edition is called the Basic Edition.
  • Both the Basic Edition and Enhanced Edition support V2 APIs. However, the Enhanced Edition no longer supports legacy APIs while the Basic Edition still supports legacy APIs.
  • If you have not integrated legacy APIs, we recommend that you directly use V2 APIs and choose the Enhanced Edition SDK.
  • If you have integrated legacy APIs, we recommend that you upgrade to V2 APIs and gradually transition to the Enhanced Edition SDK.
  • Compared with the Basic Edition, the Enhanced Edition has greatly reduced the SDK size and installation package increment.
  • Compared with the Basic Edition, the Enhanced Edition provides more new features.
  • Subsequent development of new features will only be supported on the Enhanced Edition. The Basic Edition supports only routine maintenance and fixing of existing problems.
