无法用CloudMade显示osmdroid瓷砖

Question

我想用CloudMade（或其他）工作osmdroid，但我无法显示任何瓷砖只有空白方块。我可以在登录猫唯一看到的是

找不到方法org.osmdroid.views.MapView.getScaleX，从方法引用org.osmdroid.views.overlay.SafeDrawOverlay.draw

无法解决虚拟方法5572：Lorg/osmdroid /视图/ MapView的; .getScaleX（）

的AndroidManifest.xml

我怀疑你的目标SDK太低。 Osmdroid支持SDK 7，但是如果您的设备较高，那么它将使用来自较新API的api调用。目标最新的SDK，但保持你的最小的SDK在7。
