【问题描述】：

我正在尝试使用 Geocoder 获取字符串地址的协调，我的代码在 ios 设备上运行良好，但是当我在 android 上运行它时，它显示了这个错误

这是我的代码

   return TextField(
      controller: textEditController,
      onTap: () async 
        p = await PlacesAutocomplete.show(
            context: context,
            apiKey: R.Google_api_key,
            language: "fr",
            components: [Component(Component.country, "fr")]);
        textEditController.text = p.description;
        var addresses = await Geocoder.local.findAddressesFromQuery(p.description);
        schedule.UpdateListeners(addresses.first.coordinates.latitude,addresses.first.coordinates.longitude) ;
        //final double distance = await distanceBetween( addresses.first.coordinates.latitude, addresses.first.coordinates.longitude, endLatitude, endLongitude);
      ,
      decoration: InputDecoration(
          border: InputBorder.none,
          hintText: 'Adresse, ex. 5 Rue Thénard Paris'),
    );

地点自动完成功能运行良好并返回所需地址。

【参考方案1】：

出现这个问题的原因有很多，

负纬度或语言 在模拟器中会抛出异常，而在真实设备中则不会 api 问题 有些人建议使用 Geocoder.google 而不是 Geocoder.local [Link for discussion this problem in github][1]

【讨论】：

您好 Akhrarov，感谢您的帮助，但您的解决方案都没有帮助，问题似乎与网络问题有关，我重新配置了我的模拟器，它可以工作了！

【参考方案2】：

这个问题好像和模拟器的配置有关，我在另一个模拟器上试了同样的程序，效果很好，我试过删除模拟器重新安装，问题就解决了！
