Question: I have **Galaxy tab 10.1 inch**  and I have made app and test on it, it works fine.

Now my question is will this app work on Galaxy 7 inch, Galaxy 7.7 inch, Galaxy note and Galaxy 8.9 inch 

here is the details of these devices:

 **(My Device) Galaxy tab 10.1 inch -->** 800 x 1280 pixels, 10.1 inches (~149 ppi pixel density)

**Galaxy 8.9 inch**--> 800 x 1280 pixels, 8.9 inches (~170 ppi pixel density)

**Galaxy 7.7 inch** --> 800 x 1280 pixels, 7.7 inches (~196 ppi pixel density)

**Galaxy 7 inch** --> 600 x 1024 pixels, 7.0 inches (~170 ppi pixel density)

**Galaxy Note** --> 800 x 1280 pixels, 5.3 inches (~285 ppi pixel density)

Please tell me for which device I have to make layouts again and what will be the folder names for drawable and layout

Answer: 
for Galaxy 7 inch --> 600 x 1024 pixels, 7.0 inches (~170 ppi pixel density) you can make layout folder with name "layout-large-mdpi-1024x600"....but for other device i am also unable to sort correct
