仅osmdroid地图视图网格，无需外部存储权限即可使用osmdroid？

Question

我的osmdroid地图仅显示一个空网格，为什么会这样？

我已经在这里搜索了一些相同的问题，并尝试了它，但我无法解决问题。我阅读了osmdroid需要sdcard /外部存储的权限。我不能使用它吗？因为我的设备不支持外部存储或SD卡。这是我的[[code

因此您没有提到您正在使用哪个版本的osmdroid或android，但是在配置设置上没有任何麻烦，它将默认为应用程序专用存储，应该照常工作。它应该默认为/data/data/yourAppPackageName/osmdroid/

如果默认设置不起作用（在重置配置实例之后），请尝试设置上述显式路径。
