Resolution is 1920*1080 and the actual size is 5 inch.
How to calculate the smallestWidth on android ?
Which the res folder should be used on the handset,including drawable,values and layout folder?
Firstly, i get the dpi:
dpi = root(1920*1920+1080*1080)/5 = 440.5
Then I use the formula to get the samllestWidth :
samllestWidth=1080/(dpi/160)=1080/(440.5/160) = 392.2
So the smallestWidth is 393dp
But if the manufacturer set the dpi to 480 , the smallestWidth will be :
smallestWidth = 1080/(480/160) = 360dp
