[帮助文档] 在Android开发时,SDK的使用说明及示例

本文为您介绍了在Android开发时，SDK的使用说明及示例。

[帮助文档] 如何进行App端的Android系统开发

对于Combo设备（同时支持Wi-Fi和BLE），除了可以先配网再绑定设备（即蓝牙辅助配网开发实践），还可以先绑定设备再配网，且该方式配网速度更快。当您的业务场景需要快速配网时，可根据本文档来进行App端的Android系统开发。

[帮助文档] 如何开发Android自有App中蓝牙辅助配网功能

蓝牙可以辅助纯Wi-Fi方式来配网，当Wi-Fi配网出现错误时，还可以用来反馈错误信息，帮助用户定位问题。当您的自有App需要蓝牙辅助配网功能时，请根据本文档开发Android自有App中蓝牙辅助配网功能。
