Themes trouble

I tried setting the theme to Theme.Black.NoTitleBar.Fullscreen but it crashes with the following error:

You need to use a Theme.AppCompat theme (or descendant) with this activity.

Googled around for awhile and couldn't figure it out. Android Studio doesn't seem to have that fancy manifest editor you used in the video (or at least I couldn't find it).

Any help would be greatly appreciated!

I just got that same problem in Android Studio last week! I got around it by bumping up my minSdkVersion because I was okay with supporting 4.0 and above.

So I just went back and tried to revert to API 9 for minSdkVersion. I changed it in both my manifest and build.gradle file. No errors. I ran it and verified it worked. Restarted Android Studio and verified it worked. It's supposed to work because Theme.Black.NoTitleBar.Fullscreen has been around since API 1.

I don't know why the error would be there and then go away by changing and then reverting the min SDK. Can you try that and see if you get the same behavior? If so, then we can chalk it up to a bug in Android Studio. If not, then we'll have to dig a little deeper.

I changed minSdkVersion to 9 in build.gradle and AndroidManifest.xml and the same thing still happens. Any other ideas?

I'm away from my laptop for a minute...can you try adding this line in your onCreate method (after super.onCreate)? This has worked for me before...will try shortly myself!

this.requestWindowFeature(Window.FEATURE_NO_TITLE);

Also, can you verify the syntax you're using? I sometimes still get confused as to when to use @android:style vs @style, etc. This is what I have:

<activity
    android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"

Here's one potential solution that hides some things in code: http://stackoverflow.com/q/20653305/475217
