Curious about full screen (Crystal Ball)

I'm moving along smoothly lately, just getting in to the launcher icon and settings video. Ben mentions here that we've been using full-screen mode to hide the window label, for example. This is true, and it behaves that way in the emulator.

However, for the first time, I noticed that it doesn't behave that way on my phone. It's an Epic 4G, Android 2.3.6. When Crystal Ball is running, I still have the notification bar and the app label (now "Crystal Ball") at the top of the screen.

Do you think this is simply a versioning issue, or am I overlooking something that would adjust this?

Thanks!

What does it say in your AndroidManifest.xml?

Look for the:

android:theme

in the

<application>

tags.

For example:

 <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" >
        <activity

I would guess this is device-specific or maybe version-specific. If I run the app on my 2.3.3 emulator it takes up the entire full screen. There are different ways to try hiding the Notification Bar and/or the Status bar. Here's one that deals with setting the theme:

This value worked. I actually placed the string in the Theme: field on the Application form, thinking it would generate the matching code in the appropriate spot in the .xml, but it didn't. Just another oddity (to me), but not something I need to comprehend right now.

Thanks!

Hey Mark can you explain what code snippet worked for you? I'm curious because I've never had a Theme.Black.NoTitleBar.Fullscreen not work.

Hi Ernest,

Someone in the other thread said the code block didn't work for them. My situation was a little different.

I typed Theme.Black.NoTitleBar.Fullscreen into the first place I saw "Theme", which just happened to be on the Application tab (where you fill in the info in a form). I used it there and it worked.

I flipped over to the AndroidManifest.xml tab and couldnt see the changes in the code. It turned out that it was there, in a long line that extended well to the right of the editor screen, but I found it.

Thanks,

Heh. Oh well. Glad you could work it out. I always edit the actual .xml itself.
