Android different screen size and different densities
android, android-screen-support
Solution
When I have started development in Android, I was confused about same issue.But now I have figured it out and I'm doing pretty well.
Anyways, `You are absolutely right`.you can provide different images by 4 folders for each.`i.e.: drawable-small-ldpi, drawable-small-mdpi, drawable-small-hdpi, drawable-small-xhdpi`
`But it is just waste of your time`.because you don't need to worry this much about it.Android can scale up/scale down according to the device configuration.so just provide extra images for those devices only if you don't get desired outputs for them.
As far as I know, supporting multiple devices, you have to consider `few general criteria` in your mind.
Density qualifiers: `ldpi,mdpi,hdpi,xhdpi,etc` are generally used when you want to provide different resolution images.
Size qualifiers + Orientation qualifiers: `small,normal,large,xlarge,sw600dp,normal-land,normal-port,etc` are generally used when you want to provide different layout designs.
i.e.: single pane layout,multi-pane layout,different elements in layouts according to different screen sizes.
For reference: `Download the example app` from here `and try to understand` how it is being supported for multiple screens.
I hope it will be helpful !!
Problem
I have to manage different screen sizes and different densities in my Android app. I am not getting directory structure properly. What I understand so far is there are four types of screen sizes: - small - normal - large - xlarge and different densities as well: - ldpi - mdpi - hdpi - xhdpi Now each device size (small , normal , large and xlarge) shall map against each density. Because every size can have different density, right? If yes, then we can say small screen have all the density i.e ( ldpi , mdpi , hdpi , xhdpi) same for normal, large and xlarge. The point is how I'll manage them in my drawable directories. Will there be four folders for small screen size with different size (drawable-small-ldpi, drawable-small-mdpi, drawable-small-hdpi, drawable-small-xhdpi)? And same for other screen sizes as well. If not then how I'll manage all the image in ( drawable-ldpi , drawable-mdpi , drawable-hdpi , drawable-xhdpi) folder because different screen size I'll have different size of images. Then how can a small device with different density and large device with a different size be manageable in same density folder. Please don't give me reference of any Android document as I read all that stuff. If any one can't get my point, then please let me know. I'm very confused.
