Xamarin Plugin.Geolocator가 작동하지 않습니다.

Question

공유 코드 라이브러리에서 다음 코드를 사용하여 사용자의 현재 위치를 가져 오려고했습니다. 프로젝트의

소스 Dropbox link

using System; 
using System.Diagnostics; 
using Plugin.Geolocator; 
using Plugin.Geolocator.Abstractions; 

namespace SampleApp 
{ 
    public class LocationManager 
    { 
     private DateTimeOffset timestamp; 

     private double latitude; 

     private double longitude; 

     IGeolocator locator; 

     public LocationManager() 
     { 
      asyncInitLocation(); 
     } 

     private async void asyncInitLocation() 
     { 
      try 
      { 
       locator = CrossGeolocator.Current; 
       locator.DesiredAccuracy = 50; 

       if (locator.IsGeolocationEnabled) 
       { 
        var position = await locator.GetPositionAsync(timeoutMilliseconds: 20000); 
        timestamp = position.Timestamp; 
        latitude = position.Latitude; 
        longitude = position.Longitude; 
       } 
       else 
       { 
        Debug.WriteLine("Geolocation is disabled!"); 
       } 
      } 
      catch (Exception ex) 
      { 
       Debug.WriteLine("Unable to get location, may need to increase timeout: " + ex); 
      } 
     } 

     public DateTimeOffset getTimestamp() 
     { 
      return this.timestamp; 
     } 

     public double getLatitude() 
     { 
      return this.latitude; 
     } 

     public double getLongitude() 
     { 
      return this.longitude; 
     } 

     public void refresh() 
     { 
      asyncInitLocation(); 
     } 
    } 
} 

나는 아래의 오류가 발생하고 여기 사용할 수 있습니다. Google은 나를 도왔다!

내가 뭔가를 놓치고 있습니까 :

Unable to get location, may need to increase timeout: System.NotImplementedException: This functionality is not implemented in the portable version of this assembly. You should reference the NuGet package from your main application project in order to reference the platform-specific implementation.

가 지금은 아래의 오류 메시지가 같은 packages.config 파일이 보인다? 나는 프로젝트에 nuget을 사용하여 플러그인을 추가했다.

Answer 1

문제를 다시 테스트 한 후 을 새로 작성한 후 Geolocator.Plugin을 Android Project에 추가했습니다.

참고 :

플러그인 설명서를 말한다 :

ACCESS_COARSE_LOCATION & ACCESS_FINE_LOCATION 권한이 필요 하지만 라이브러리가 자동으로이 추가됩니다. 또한 사용자가 Marshmallow를 실행하는 경우 플러그인은 에 자동으로 런타임 권한을 요청합니다.

하지만 Android에서이 권한을 수동으로 추가해야합니다. MainActivity가

<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="pt.sushiathome.shared_geolocator"> 
    <uses-sdk android:minSdkVersion="15" /> 
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> 
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 
    <application android:label="shared.geolocator"> 
    </application> 
</manifest> 

:

Button button = FindViewById<Button>(Resource.Id.myButton); 

button.Click += async delegate 
{ 
    try 
    { 
     var locator = CrossGeolocator.Current; 
     locator.DesiredAccuracy = 50; 

     if (locator.IsGeolocationEnabled) 
     { 
      var position = await locator.GetPositionAsync(timeoutMilliseconds: 10000); 
      position.ToString(); 
     } 
     else 
     { 
      System.Diagnostics.Debug.WriteLine("Geolocation is disabled!"); 
     } 
    } 
    catch (Exception ex) 
    { 
     System.Diagnostics.Debug.WriteLine("Unable to get location, may need to increase timeout: " + ex); 
    } 
}; 

그냥 position.ToString();에 중단 점을 배치하고 내가 위치를 가지고 같은

는 매니페스트 보인다. (에뮬레이터와 실제 장치에서 테스트.)

NOTE2에게 : 에뮬레이터에서 GPS에 전환

Answer 2

내가 같은 오류가 발생했다를, 나는 클린업으로 해결 솔루션을 다시 빌드하고 모든 프로젝트에 종속성이 추가되었는지 확인하십시오.
