Create Loading Page before initialiseAllResourceGroups

[Whisperd130]

Hi All,
In my Android Device the initialize stage shows black screen that's not very nice to see.
So I want to create a overlay page before locateResources() and initialiseAllResourceGroups() in Android System.
But how to show a loading page before initialiseAllResourceGroups(), and what specific ResourceGroup I need to initialize in Android system?

My setup: Ogre 1.10.2 on Android 4.4.2

Thanks in advance.

Thank you for advance.
This way it can shows a loadingbar with mouse, it's nice.
But I want to get a picture to mask the black screen in the beginning when OGRE system start.
Is that anything to just show a picture layer?

there is no predefined component for that. However you can take a look how the trays system sets its background here:

Hi,

you can derive from Ogre::ResourceGroupListener and override the corresponding methods. I rotated e.g. a picture and printed text while loading the resources.
