ERROR: 9-patch image C:\...\res\drawable\appwidget.9.png malformed. Frame pixels must be either solid or transparent (not intermediate alphas).

this is the problem with latest adt that is 20.0.3. you can instead rename the *.9.png to *.png and start working. i think this is the bug with the adt only, since for 18.0.0 version adt it doesnt prompts for this type of error and works finethis is the problem with latest adt that is 20.
