问题描述
我不明白为什么 locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
返回的位置空。我把所有的权限,但其reutning 空
。
如果(isGPSEnabled){
如果(位置== NULL){
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES,这一点);
Log.d(全球定位系统,GPS功能的);
如果(locationManager!= NULL){
位置= locationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
如果(位置!= NULL){
纬度= location.getLatitude();
经度= location.getLongitude();
}
}
}
}
解决方案
我有此相同的问题。这是因为我的设备没有存储最后已知位置。我只是去上谷歌地图,并明确指出我的位置有GPS,那么这个值是返回getLastKnownLocation()
i dont understand why locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
return the location null. I gave all permission but its reutning null
.
if (isGPSEnabled) {
if (location == null) {
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
Log.d("GPS", "GPS Enabled");
if (locationManager != null) {
location = locationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
}
}
}
解决方案
I had this exact same problem. It was because my device was not storing a last known location. I simply went on to Google Maps and pinpointed my location with GPS, then a value was returned for getLastKnownLocation()
