反向地理编码 - 服务不可用 - 重新启动设备无法明确解决 - 批评我的手动反向地理编码

Question

有时我会Service Not Available在我的申请中遇到例外情况.大多数时候,没有问题.但有时它会发生.(该应用程序仍在开发中)

解决问题的唯一方法是重启手机.关于支持论坛的相关问题38009.但我从评论中理解的是,重启设备可以永远解决问题.

它是否正确？
因为在我的情况下,错误可以返回(频率:我认为每月一次或两次,我在这个应用程序上是全职).

有没有办法从应用程序内部重新启动地理编码器？

我唯一的解决方案是提供一个替代解决方案,以防万一"手动"获取地址,如下所示.你有更好的吗？

@mike 的链接指出：使用 GeoCoder 处理程序和 asynctask 类的后备实现都需要同步 - 就像没有服务我们可以从 URL 获取地址一样。不幸的是，这是我们可以提供的唯一解决方案@Poutrathor。

请参阅此处服务不可用 - Geocoder Android

此外，我们不能强迫用户重新启动，但至少告知解决方案。
