我想寫一個應用程序獲取當前位置並實時顯示經度和緯度。但是,當我運行這個應用程序時,GPS似乎並沒有搜索到一個位置,並嘗試獲得修復。我不知道爲什麼會發生這種情況。我錯過了什麼嗎?如果我打開地圖應用程序,位置立即得到修復。但在我的應用程序中,gps並未在通知欄中搜索一個或至少一個,它沒有顯示像通常由地圖應用程序顯示的「搜索gps」的任何內容。熔合位置不工作Android

我已經測試這在Android 6和7的任何一方不工作。任何幫助,將不勝感激。
否您的解決方案尚未解決問題。問題依然存在。 – speedster01
請按照下列步驟 https://developers.google.com/android/guides/setup 檢查您的mGoogleApiClient通過認證,並連接在監控日誌,而且onConnected()方法是在你的回調GoogleApiClient.ConnectionCallbacks運行 – typecode
我使用了您提供的鏈接僅用於初始設置功能。我檢查了; google客戶端連接並且onConnected()方法也運行。 locationChanged()方法也被調用。只是它是一次又一次的相同的位置。除了未在通知菜單中顯示gps圖標之外,該位置似乎沒有變化。 – speedster01
