问题 I have a manifest file and use the mt command in makefile to add it into one of my exe files. After it's installed. If I use DPI Awareness Enabler or check the registry in HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers, it does NOT show anything interesting.

问题 I have a problem with supporting different screen sizes. My application has different drawables for mdpi (320x480), hdpi (480x800) or ldpi (240x432).
