推薦答案
我也遇到了同樣的問題.這是因為我的設備沒有存儲最后一個已知位置.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()
