ZERO_RESULTS在检索veterinary_care和pet_store Android Studio的场所类型

Question

我一直在谷歌位置搜索，通常我能很好地得到结果，但最近我只能得到兽医_护理和宠物_商店的ZERO_results，但医院工作得很好。为什么成功回调直接指向我的else语句ZERO_RESULTS？

你知道这里出了什么问题吗？

Answer 1

检查后，在指定veterinary_care和pet_store时，附近搜索似乎返回"ZERO_RESULTS"，因为您所在的位置附近没有开放的宠物店和兽医诊所。请注意，标记为永久/临时关闭的场所不会出现在场所搜索[1](例如附近搜索(结果中。您可以通过场所详细信息[2]验证场所是暂时关闭还是永久关闭(如果permanntly_closed字段为true(。

你可以使用某个地点附近的一家已知的开放宠物店来检查这种行为。您可以为附近搜索请求提供特定位置。测试时可以尝试以下示例。
