java - RequestLocationUpdates 抛出 Java.Lang.Exception

Question

方法 OnResume (_locationManager.RequestLocationUpdates) 在 Samsung Note 1 上引发“类型为‘Java.Lang.Exception’”(适用于 SGS4)。

权限:添加了 android.permission.ACCESS_FINE_LOCATION 和 android.permission.ACCESS_COARSE_LOCATION。

可以在 github 上找到源代码:https://github.com/constructor-igor/sms2

[Activity (Label = "sms2", MainLauncher = true)]
public class MainActivity : Activity, ILocationListener
{
...
    private LocationManager _locationManager;
...
    protected override void OnCreate (Bundle bundle)
    {
       ...
      _locationManager = (LocationManager)GetSystemService(LocationService);
    }
    protected override void OnResume()
        {
            try
            {
                Log.Debug ("OnResume", "");
                base.OnResume ();

                m_smsSentBroadcastReceiver = new SMSSentReceiver();
                m_smsDeliveredBroadcastReceiver = new SMSDeliveredReceiver();

                RegisterReceiver(m_smsSentBroadcastReceiver, new IntentFilter("SMS_SENT"));
                RegisterReceiver(m_smsDeliveredBroadcastReceiver, new IntentFilter("SMS_DELIVERED"));

                _locationManager.RequestLocationUpdates(_locationProvider, 0, 0, this);
            }
            catch(Exception e) {
                Toast.MakeText(Application.Context, String.Format("OnResume failed, becasue '{0}'", e.Message), ToastLength.Long).Show();
            }
        }

您尝试使用的提供商在该设备上不存在。您可以在 documentation 中查看 IllegalArgumentException 的原因
