layout-sw600dp values-sw600dp Android example of use
AD MOB
Why the app selects data from basic layout folder if smallest width is higher then the number in folder name?
Example 1
layout-sw600dp values-sw600dp (smallest width sw for data usage from this folder is 600dp density independent pixel!!!!!)
Device screen resolution is 1200 x 900 px (pixel) Wow, app to be select data from sw600dp folder! Realy?
DPI of device screen - dot per inch (pixel per inch) is 480 pixel it is wery important number!
In our case smallest dimension of screen must be at least 1800 real - physical pixels (1800 px / 3 ratio(dpi/160) = 600 dp (dip density independend pixels) to be used data from folders values-sw600dp and layout-sw600dp.
Example 2 see Example 1 abouve
Device: Nexus 7 (2012) selected from Android Studio tool layout editor
Resolution: 800x1280 px
DPI: tvdpi (approximately 213dpi)
Ratio: 1.33 (213 / 160)
Smallest width in px: 800
Convert px to dp: 601.5 (800 / 1.33)
Result:Smallest width is 601.5dp The App to be used data from folders values-sw600dp and layout-sw600dp.
Example 1
layout-sw600dp values-sw600dp (smallest width sw for data usage from this folder is 600dp density independent pixel!!!!!)

DPI of device screen - dot per inch (pixel per inch) is 480 pixel it is wery important number!
- App selects smallest dimension of screen. In our case 900 px
Medium screen have 160 dpi (The density-independent pixel is equivalent to one physical pixel on a 160 dpi screen, which is the baseline density assumed by the system for a "medium" density screen.). - App calculate ratio 480 / 160 = 3 (The conversion of dp units to screen pixels: px = dp * (dpi / 160))
- App calculate smallest dimesnion of screen in dp 900 / 3 = 300 dip or dp (density independed pixel).
- App selects data from basic values and layout folder because sw600dp is greater than 300dp.
In our case smallest dimension of screen must be at least 1800 real - physical pixels (1800 px / 3 ratio(dpi/160) = 600 dp (dip density independend pixels) to be used data from folders values-sw600dp and layout-sw600dp.

Try some solution - each individually or all
- Check AndroidManifest.xml activity declaration
<activity android:name=".EnableProfileActivity" android:label="@string/app_name" /> - Delete BUILD folder in module tree and Clean / Rebuild project
- Restart Android Studio
"id cannot be resolved or is not a field” error
If you copy project to workspace or some code from other project you can get this error.
Try remove or add import your R file:
Check xml files.
Clean project by menu Project-Clean
Maybe you have to create new project end copy old source files to new project folders.
