Learn application development the question arose. Currently studying the data retrieval api for the application.
What resolution is best to prepare the image to load it into the application by means of api to load not long and the quality was not bad, the picture is planned for all width of the screen.
Is there a happy medium between image quality and optimal download speed ?
Or under different devices to load different images ?
I certainly understand that on mobile devices it is better to impose the dp and about @2x @3x xxhdp etc ... But still get the image from the external server has a resolution in pixels .
Thanks in advance !
