I\'ve been following the new steps for Android L here: http://developer.android.com/preview/material/theme.html I\'ve have been trying to change the colors of the status bar but
I have the same problem. And I fix this by change sdk to
<uses-sdk android:minSdkVersion="L" android:targetSdkVersion="L" />
Hope it can help.
I don't have enough rep to elaborate upon @Allavaz's answer, but his solution worked for me.
I changed the generated theme name in both styles.xml and AndroidManifest.xml from AppTheme
to a different name.
I'm using Android Studio 0.8.2.
I made it work by changing the style name in styles.xml and in AndroidManifest.xml.
as of oct 2014, It will not be visible in the layout preview but works when viewed inside on the emulator.
