Question

I want to make my application to multiple screen support. so to achieve this i read the Android developers guildeline https://developer.android.com/guide/practices/screens_support.html and i have created the different drawable and layout folders to put different size of images.

I tested the application in different devices and it looks fine in those devices, while i found that in one of 7″ tablet the images are too small. to confirm this i created simple project and put same name of images in different folder and found that this device uses ldpi drawables and in generally the size of ldpi drawable used to be 36x36 and that causes the issue, if i increase this drawable size then it will not compatible with other low-density devices.

Here is the Dispaly Metrics of the device in which i am having a problem.

{density=0.75, width=800, height=444, scaledDensity=0.75, xdpi=160.0, ydpi=160.42105}

How to deal with this problem ? if anyone have this issue before then please give me some advice. any idea and help will be appreciated.

Thanks & Regards

You can get more control over this:

• Specify multiple different images for different screen resolutions and densities. To do so read supporting multiple screens. If you need even more precision in image scaling and quality you can use the fundamental size of screen attribute which is sw<N>dp – you can specify the smallest width of the screen where your image should be used. This is a qualifier name for a resource folder.

Some values you might use here for common screen sizes:

• 320, for devices with screen configurations such as:
  1. 240×320 ldpi (QVGA handset)
  2. 320×480 mdpi (handset)
  3. 480×800 hdpi (high density handset)
• 480, for screens such as 480×800 mdpi (tablet/handset).
• 600, for screens such as 600×1024 mdpi (7″ tablet).
• 720, for screens such as 720×1280 mdpi (10″ tablet).

Just specify your device width and put your edited image that fits the best in corresponding sw<N>dp folder in your case sw<444>dp.

You should also have a look at other qualifiers that make Android choosing image at runtime (screen density, Available width, Available height, Screen size or Screen aspect). By combining these qualifiers and testing carefully you will be sure that the user has the best experience on each device.

Shortly, put your image under drawable-sw<444>dp folder. (444-smaller screen metric)
