My application is supporting 3 type of density ldpi (120),mdpi(160),hdpi(320) and for that we have three folder for resources (ldpi,mdpi,hdpi).
But my problem is occ
you can use below combination for Layout for HTC sensation XE (540x960) :
res/layout-w540dp-h960dp/layout.xml
this will use for pick layout for this device and for drawable it will pick image from hdpi because in this developer site 256 dp come in range of hdpi . http://developer.android.com/guide/practices/screens_support.html.
hope this will help you.
