title: Android: How to remove the Activity Title Bar?
body: <p>I am wanting to get rid of the Activity Title Bar as it is annoying to have. However, I do not want to have a fullscreen activity.I have tried just adding <code>@android:style/Theme.NoTitleBar</code> to activity and <code>android:theme="@android:style/Theme.NoTitleBar.Fullscreen</code> to the manifest file, but I keep getting the error: <code>java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity</code>. Nothing seems to help.</p>
