Android Question Problem compiling

[Betan]

Hi everybody, my English is very bad but I need your help. When I try to compile my applications the following message appears:

res \ values-v20 \ theme.xml: 3: Error: Error retrieving parent for item: No resource found that matches the given name '@Android: style / Theme.Material'.

How can I fix this problem?

You most likely will found cause of your problem from Manifest. Did you forget to create resource for your theme?
