Check your layout and make sure the Show Title is also off there.

as for the window that pops up right before your app loads please provide your activity_create sub.

This is my activity_create. I added a breakpoint when I load my apps main screen. The screen that pops up happens before line 74 is run.



This is the screen that pops up for a couple of seconds. I was able to capture it:


Then when I go past the debug statement (line 74), my app loads:

The title is also not selected on the layout of my main screen. Just verified this as well.

You need to turn the title off in the Activity Attributes region:

B4X:

#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: True    'Change to false
#End Region

Do you see the black screen when the app is run in release mode?

Yes I do see the screen in release mode. What is making it even more confusing is it is happening before my first command in the Starter. It is not evening making it to my Main module before the screen pops up. Below I added a breakpoint to line 17 and the screen popped up already.

There are a few threads about this on the forum, with a quick search I found these:

Maybe one of these will help.

Steve,

Thanks for this info. I will try to change the manifest to see if this helps. Since it is happening immediately in the Startup, I assume the manifest is where I can take care of this. Never thought to make any changes there. Learn something new everyday!

I just want to thank everyone for their input, I added the following in my Manifest and this resolved my issue:

SetActivityAttribute(Main, android:theme, "@android:style/Theme.NoTitleBar.Fullscreen")

Thanks,
Warren

Your solution is not good enough as it will cause your app to use Android 2 theme.

You can instead add this to the manifest editor:

B4X:

SetApplicationAttribute(android:theme, "@style/MyTheme")
CreateResource(values-v20, theme.xml,
<resources>
  <style name="MyTheme" parent="@android:style/Theme.Material">
   <item name="android:windowActionBar">false</item>
  <item name="android:windowNoTitle">true</item>
  </style>
</resources>
)
CreateResource(values-v14, theme.xml,
<resources>
  <style
  name="MyTheme" parent="@android:style/Theme.Holo">
     <item name="android:windowActionBar">false</item>
  <item name="android:windowNoTitle">true</item>
  </style>
</resources>
)
