 "location unavailable"}

Answer 1

是Android设备还是模拟器？

如果我们谈论的是android设备，请检查要启用的GPS，因为某些手机无法启用此功能。

在模拟器上，该插件无法正常工作。

Answer 2

对于模拟器，你必须先设置一个默认位置，

go to emulator settings -> Location -> Search for a place(set the marker) -> click 'Set Location'

然后在您的组件中，您可以执行以下操作：

import { Capacitor, Plugins } from "@capacitor/core";
const { Geolocation } = Plugins;  // don't inject in ctor()

Geolocation.getCurrentPosition({
        enableHighAccuracy: true,
      }).then((resp) => {            
        this.lat = resp.coords.latitude;
        this.lng = resp.coords.longitude;
      }).catch((error) => {
        console.log('Error getting location', error);
      });

并检查 GPS 权限，您可以使用以下内容

isGpsPermissionEnabled(permissions: AndroidPermissions): Promise<boolean> {
    return await new Promise((resolve, reject) => {
        if (Capacitor.isNative) {
            permissions.checkPermission(permissions.PERMISSION.ACCESS_FINE_LOCATION).then(
                rs => resolve(rs.hasPermission),
                err => {
                    console.log("something went wrong")
                }
            );
        }
        else { resolve(true); // for browsers
         }
    })
}
