lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER)总是为false，但是我网络确实是开了的，GPS就可以判断，谁知道怎么回事吗？

[lbhappy1990]

lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
我的在这里就直接抛异常了

[国仔饼]

楼主解决了吗，我也遇到同样的问题

[faith9111]

三星i9100国产的没有google服务，所以没有那个network组件，所以总是返回false，目前我也正在想解决办法！同求啊

[机器法师]

楼主如何解决的啊？？求分享！！

[OOOONO]

有可能是手机或者平板，设置中，位置信息使用权限中GPS或者WIFI或者网络的使用权限没有开启
