java.lang.IllegalArgumentException：提供者=网络

Question

我的安卓应用有时会抛出这个异常：

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

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

在这一行：

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

我做错了什么？

我使用网络枚举提供程序。

Answer 1

首先检查LocationManagers NETWORK_PROVIDER是否开启

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