問(wèn)題描述

我不明白為什么 locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); 返回位置 null.我給予了所有許可，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();
                    }
                }
            }
        }

我也遇到了同樣的問(wèn)題.這是因?yàn)槲业脑O(shè)備沒(méi)有存儲(chǔ)最后一個(gè)已知位置.我只是去谷歌地圖并用 GPS 精確定位我的位置，然后為 getLastKnownLocation() 返回一個(gè)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()

這篇關(guān)于locationManager.getLastKnownLocation() 返回 null的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
