在我的項目中，我試圖通過使用LocationManager將我的當前位置發佈到服務器。爲此，我通過在位置管理器中使用OnLocationChanged方法獲得了緯度和經度值。同樣在按鈕單擊事件中，我嘗試使用地理編碼器功能將長整型值轉換爲Address。但它使我的應用程序崩潰。GeoCoder中的IndexOutOfBoundsException
按鈕單擊代碼：

而且當我檢查lat和長值它顯示像（13.1270,803.2701）
GeoCoder需要Google API，你使用它嗎？ – dmaxi 2013-05-09 09:52:27
你可以添加異常的logcat嗎？ – AlexBcn 2013-05-09 09:55:23
