How to support multi-resolution only with high resolution images

Question

My Folder of drawable contains drawable-ldpi\drawable-mdpi\drawable-hdpi\drawable-xhdpi\drawable-xxhdpi to match the device whose resolution is 480x320\800x480\960x640\1280x720\1920x1080.I put a series of images into the folder of drawable-xxhdpi now,and the arrangement looks good in the testing machine with the same high resolution. My question is how to support multi-resolution phone using the high resolution images.Taking into account adding the picture resized to a smaller one to the appropriate folder will increase the size of application,are there any other methods?

Answer 1

Check this reference, http://developer.android.com/guide/practices/screens_support.html, specially section "Density independence".

Please consider the system scales drawable resources to the appropriate size, based on the current screen density, if necessary. So, for example, if you provide a drawable resource for the highest resolution, you don't have to produce also different images for other densities, because the system will do that for you.

Answer 2

Here is a reference to multi device options.

You don't need to put resources in anything but res/ layout/ or drawable/ but if you want your program to have a better experience on multiple devices with different screens / density / languages you may want to consider that you have that option.

Answer 3

You must customize image in your folder.You can source high image resolution but you must changend and customize image.
