Here are some examples of how input paths translate to resource paths afterimport:

• Android density qualifier: hdpi
• Android density qualifier: xxhdpi
• Input path: /UserFolder/icon1/abc-xxhdpi/icon.pngResource path://src/main/res/drawable-xxhdpi/icon.png
• iOS scaling factor: @2x
• Input path: /UserFolder/icon1/icon@2x.pngResource path://src/main/res/drawable-xhdpi/icon.png
• iOS scaling factor: @2x
• Input path: /UserFolder/icon1/icon@2xalternate.pngResource path://src/main/res/**_drawable-xhdpi**/icon_alternate.png

Drag and drop drawables into your layout

You can drag and drop drawables from the Resource Manager directly onto alayout. When you drop a resource onto a layout, the Resource Manager creates acorresponding for that drawable, as shown in animation 1:

You can also drag and drop onto the XML view in the Text tab, as shown inanimation 2:

When dropping a drawable onto a layout in the Text tab, the generated codediffers depending on where you drop the layout:

• If you drop a drawable onto a blank area, the Resource Manager generates acorresponding .
• If you drop a drawable onto an existing element, the ResourceManager replaces the corresponding source attribute.
