热力引擎 SDK 提供了专门设置 GAID 的接口，方便开发者灵活集成，通常情况下 SDK 会自动获取 GAID，开发者不需要手动设置，手动设置时将进行保存，在下一次传入前不会修改、不会删除。重复设置时保存最后一次传入的值。
方法示例
public void setGaid(String gaid);参数说明
| 参数名称 | 参数含义 | 参数类型 | 是否必传 |
| gaid | 设备的 gaid | String | 否 |
调用示例
SolarEngineManager.getInstance().setGaid("开发者获取的gaid");注：如果开发者在热力引擎SDK初始化时配置了isGDPRArea(true),此方法不生效
