cvc-enumeration-valid: Value '280dpi' is not facet-valid with respect to enumeration '[ldpi, mdpi, tvdpi, hdpi, xhdpi, 400dpi, xxhdpi, 560dpi, xxxhdpi]'. It must be a value from the enumeration.

Error parsing D:\sdkforas\android-sdk-windows\system-images\android-22\android-wear\x86\devices.xml

解决方法：

用/sdk/tools/lib/devices.xml去替换system-images\android-22\android-wear\x86\devices.xml和system-images\android-22\android-wear\armeabi-v7a\devices.xml中的devices
