Android: cannot resolve appcompat-v7 themes
In themes.xml , I would like to change a theme from Theme.Holo.Light.DarkActionBar to Theme.AppCompat.Light.DarkActionBar but I get: cannot resolve symbol '@android:style/Theme.AppCompat.Light.DarkActionBar' In the gradle file I added: compile 'com.android.support:appcompat-v7:22.1.1' I am using: compileSdkVersion 22 buildToolsVersion "22.0.1" I have also run gradle's clean command, but nothing seems to change. Any ideas? The AppCompat themes are not part of the built-in styles. You have to reference them without the '@android:style' prefix. Just use something like: <style name="AppTheme"
