Android真实设备上的Geocoder.getFromLocation grpc失败 [英] Geocoder.getFromLocation grpc failed on Android real device

问题描述

我需要从经度和纬度中得出城市和州. Geocoder会执行此功能以获取城市和州.但是仅在 Android真实设备上，我在下面的行中收到错误java.io.IOException: grpc failed.在 模拟器 中正常运行.

I need to get the city and state from latitude and longitude. Geocoder does this function to get the city and state. But I am getting an error java.io.IOException: grpc failed in below line only on Android real device. It is working fine in emulators.

new Geocoder(context).getFromLocation(latLng.latitude, latLng.longitude, 1).get(0);

我也一直在使用Asynctask调用此函数，这在另一篇文章 Geocoder grpc失败中建议堆栈溢出，但对我没有任何作用.

Also I have been calling this function using Asynctask which is suggested in another post Geocoder grpc failed in stack overflow but nothing works for me.

我也重新启动了设备，但仍然失败.

And I have restart the device as well but still it is failing.

此处需要帮助.预先感谢.

Help needed here. Thanks in advance.

注意:我在Google Pixel XL，Samsung S6 edge和Samsung S4中进行了测试.

Note: I tested in Google Pixel XL, Samsung S6 edge, Samsung S4.

推荐答案

这似乎是一个持续存在的问题，已在Google问题跟踪器中针对实际设备和仿真器进行了报告.您可以参考以下错误:

It looks like this is ongoing issue that was reported in the Google issue tracker both for real devices and emulators. You can refer to the following bugs:

https://issuetracker.google.com/issues/64418751

https://issuetracker.google.com/issues/64247769

不幸的是，Google尚未解决这些问题.

Unfortunately, Google haven't solved these issues yet.

作为解决方法，您可以考虑使用Geocoding API网络服务.请注意，您可以在Github上找到用于Web服务的Java客户端库:

As a workaround you can consider using the Geocoding API web service. Please note that there is a Java client library for web services that you can find on Github:

https://github.com/googlemaps/google-maps-services-java

使用Java客户端库用于Web服务，您可以实现反向地理编码查找，而该反向地理编码查找不会给您带来本机Android Geocoder遇到的错误.

Using Java client library for web services you can implement reverse geocoding lookup that shouldn't give you the error that you experience with native Android geocoder.

客户端库的Javadoc位于
