我使用osmdroid和Mapnik！我的问题是当我使用geo fix命令时，我可以在屏幕上看到经度和纬度的新值而不是位置，我的意思是我的地图不会移动到我的新位置。有人可以帮忙吗我总是收到此错误：10-29 10:31:43.649: I/dalvikvm(309): Could not find method android.animation.ValueAnimator.ofFloat, referenced from method org.osmdroid.views.MapController.<init>
这是我的代码：

答案 0 :(得分：0)
我想你的问题是这个
java.io.IOException：服务不可用
观看这两个链接，因为它似乎是一个常见的错误
Service not Available - Geocoder Android
Service not available while calling geoCoder.getFromLocation()
这是解决问题的两种常用方法： 1.重启你的设备。也许你通过设置手机禁用了该服务 2.添加
uses-permission android：name =“android.permission.INTERNET”
到你的清单
