Question

I am implementing an AbstractAccountAuthenticator and I cannot find any information regarding the dimensions of the icon, and smallIcon drawables required.

There is a SampleSyncAdapter which is a sample demo for implementing the above (It also demonstrates how to implement an AbstractThreadedSyncAdapter), but it only defines 1 drawable resource for both icon and smallIcon.

Does anyone know the standard and required pixel sizes for both of these resources?

Answer 1

For high-density screens (drawable-hdpi):

• smallIcon: 36×36 px
• normal: 72×72 px

for medium-density screens (drawable-mdpi):

• smallIcon: 24×24 px
• normal: 48×48 px

One drawable resource for both in /drawable is the default drawable resource, and it’s designed for normal screen size and a medium density. The system scales default density resources up for high-density screens and down for low-density screens so it’s better if you make a directory for hdpi and another one for mdpi with the given size of icons.

Hope that helps.
