Lately at work I’ve been dealing with doing apps for multiple Android devices. I put together a simple image for my findings. Note that the orientations for the Blackberry devices aren’t exact, but the sizes are (click image for full size version)
A list of the devices mentioned here are:
Galaxy Note (800×1280)
Galaxy Note II (720×1280)
iPhone Retina (640×480)
Droid 3 and Droid 4 (540×960)
Sony Ericsson LT15i & Droid 2 (480×854)
Galaxy S I, Galaxy S II, Galaxy SIII (480×800)
Blackberry Bold Touch 9900 (640×480)
Blackberry Torch (360×480)
T-Mobile Concord (320×480)
Blackberry Curve (320×240)
This image is to help with designing apps for devices. Layouts and making apps for multiple devices in android is a completely different discussion..
