我有一個GWT應用程序,它使用Google Maps和Im試圖創建一個使用Googele的geocoder類獲取LatLng地址。Java + Google Maps API + GWT +地理編碼嘗試:在運行時獲取此異常 - 編譯良好
這是我的代碼:
Geocoder gc = new Geocoder();
gc.getLatLng(this.testAddress, new LatLngCallback()
{
public void onFailure()
{
System.out.println("ERROR: Could not obtain the Coordinates for address" + testAddress);
}
public void onSuccess(LatLng point)
{
System.out.println("For Address= "+testAddress +"are Latitude: "+point.getLatitude() + "Longitude: "+ point.getLongitude());
}
});
它編譯罰款,但在運行時拋出此異常:

林不知道這是什麼異常意味着,可以someoone幫我明白了嗎?謝謝
