我在我的android应用程序中使用openstrret地图，我使用OSM在我的国家/地区添加了酒店，但是当我运行我的应用程序时，我得到运行时异常，我不知道出了什么问题，而且不能找到导致异常的原因
这是我的代码：

答案 0 :(得分：0)
原因是你在编译时有osmdroid.jar但在运行时没有。这个jar没有加载到bin目录中，这是apk的lib目录。
将此jar加载到您的apk 右键单击项目 - ＆gt; properties-＆gt; java buildpath-＆gt; order and export＆gt;检查osmdroid jar
或
将osmdroid jar复制并粘贴到libs文件夹中，然后将其从buildpath中删除（othervise将两个相同的jar添加到bin目录中，这将导致另一个问题）
