I assume you are using layouts for 10 inch and 7 inch devices are layout-sw720dp and layout-sw600dp then you just create drawable-sw720dp and drawable-sw600dp, also in the case of high density for those xlarge and large screen devices then append the corresponding density to the drawable folder . For example use drawable-sw600dp-hdpi for high density 7 inch tablets like ASUS MeMO Pad HD 7'. Now resource for large and xlarge are solved
Now Consider the drawable-sw360dp devices.
- drawable-sw360dp/layout-sw360dp are for phablet devices like Note1,Note2, Micromax CanvasHD,S3.
- The above mentioned devices are XHDPI devices. For using drawables either you can use drawable-xhdpi or use drawable-sw360dp-xhdpi
Thus you can distinguish resources for s3,s4 from xlarge and large screen devices.
Note : S3 and s4 taking images from drawable-sw360dp-xhdpi because smallest width of those devices are 320dp. You can check the device display information by installing screen info app from the playstore.
