Actually you are giving wrong directory name for your screen .you can refer this from developer site go here https://developer.android.com/guide/practices/screens_support.html#NewQualifiers
in that site See Table No :2 for qualifers for screen size
also one line you can find in that is :
If the available height is a concern for you, then you can do the same using the hdp qualifier. Or, even combine the wdp and hdp qualifiers if you need to be really specific.
For Specify use of Screen Size 540x960 ,you need to add layout like below and it is valid way to define width and height used for that xml layout.
res/layout-w540dp-h960dp/any layout which you need put in side this folder
