java.lang.IllegalArgumentException異常：供應商=網絡

Question

我的Android應用程序有時會拋出該異常：

java.lang.IllegalArgumentException: provider=network 
at android.app.ActivityThread.handleServiceArgs(ActivityThread.java:2517) 
at android.app.ActivityThread.access$1900(ActivityThread.java:135)

Caused by: java.lang.IllegalArgumentException: provider=network

at android.location.LocationManager._requestLocationUpdates(LocationManager.java:686) 
at android.location.LocationManager.requestLocationUpdates(LocationManager.java:508) 

在這一行：

mLocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, mNetlocListener); 

我做了什麼錯？

我使用網絡枚舉提供程序。

Answer 1

首先檢查LocationManagers NETWORK_PROVIDER是否啓用

if (mLocationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) { 
     mLocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,mNetlocListener); 
    }
