问题描述

I want to know if the device has GPS or not, how could I do that for the devices below v 5.0 ?

推荐答案

有一个在文档的<一个href=\"http://www.blackberry.com/developers/docs/4.6.0api/javax/microedition/location/LocationProvider.html\"相对=nofollow> 位置提供商 。尝试在不同的情况下，一些设备，这个code和我认为它应该工作：

Have a look at docs for Location Provider. Try this code on a few devices in different situations and I think it should work:

try {
    LocationProvider lp = LocationProvider.getInstance(null);
    if (lp == null) {
        //Device doesn't currently have GPS enabled
    } else {
        //Device has GPS enabled
    }
} catch (LocationException le) {
     //Device's GPS is currently permanently disabled
}
