我正在尝试为我的Android项目初始化SKMaps库，并且我不断收到导致应用崩溃的FileNotFound异常。这是堆栈跟踪：

我需要确定/确认将项目中的所有文件正确放入哪里以及这行代码是否正确加载.zip文件：
final SKPrepareMapTextureThread prepThread = new SKPrepareMapTextureThread(this, this.getApplicationContext().getExternalFilesDirs(null).toString() + "/" + "SKMaps/", "SKMaps.zip", this);
我没有通过它在API指南中说明的gradle任务执行此操作，而是将jar添加到构建路径，然后假设使用SKMaps.zip文件准备地图。
