问题描述
我不明白为什么 locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); 返回位置 null.我给予了所有许可，但它的 reutning null 除外.
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();
}
}
}
}
推荐答案
我也遇到了同样的问题.这是因为我的设备没有存储最后一个已知位置.我只是去谷歌地图并用 GPS 精确定位我的位置，然后为 getLastKnownLocation() 返回一个值
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()
