Answer 1

Have you given the same name to all layout file, for e.g. main.xml, i mean to say give the same name to xml layout files and places in the particular folder. It will automatically managed by Android itself, programmer need not to bother about the same.

I made my comment as answer as this is right as per vnshetty's comment above. So that other answers may not be selected as accepted wrongly.

To help you target some of your designs for different types of devices, here are some numbers for typical screen widths:

320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).
480dp: a tweener tablet like the Streak (480x800 mdpi).
600dp: a 7” tablet (600x1024 mdpi).
720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).

For other cases in which you want to further customize your UI to differentiate between sizes such as 7” and 10” tablets, you can define additional smallest width layouts:

res/layout/main_activity.xml # For handsets (smaller than 600dp available width)
res/layout-sw600dp/main_activity.xml # For 7” tablets (600dp wide and bigger)
res/layout-sw720dp/main_activity.xml # For 10” tablets (720dp wide and bigger)

layout-medium does not exist - should use layout-normal instead

Also are you specified min api version? it will works only if you specify <uses-sdk android:minSdkVersion="4" /> or higher in your manifest file.
