Android(安卓)解决 GetLastKnownLocation(provider) = null

事情的起因就是我用系统的GetLastKnownLocation输出结果永远是null。后来看大家说这个方法在室内90%都不管用。

于是查了国内各大网站给出了两个解决办法：

1.while(GetLastKnownLocation(provider) = null){

GetLastKnownLocation = null

}

2.locationManager.setTestProviderEnabled(provider1, false);

然而这两种方法并没能解决我的问题。只是疯狂在while里循环，知道我的App崩溃。。。

最后查询StackOverflow得到解决办法。

用如下办法获取Last Location

LocationManager mLocationManager;Location myLocation = getLastKnownLocation();private Location getLastKnownLocation() {    mLocationManager = (LocationManager)getApplicationContext().getSystemService(LOCATION_SERVICE);    List<String> providers = mLocationManager.getProviders(true);    Location bestLocation = null;    for (String provider : providers) {        Location l = mLocationManager.getLastKnownLocation(provider);        if (l == null) {            continue;        }        if (bestLocation == null || l.getAccuracy() < bestLocation.getAccuracy()) {            // Found best last known location: %s", l);            bestLocation = l;        }    }    return bestLocation;}

结果很成功。

激动之余记录一下，并分享给大家。
