I try to create a custom splash screen for android device,and i follow some tutorials to get that, but i didn't get output which i expected.  Here i am attaching my OML file to your reference, please anyone help me to get this output. Below i mentioned 2 url's which i tried.

So far as I see you didn't apply the "blink" class to anything in the splash screen.

In the OML that I put here I just apply that class to the logo:

and it blinks.

See the attachment.

Hope this can help.

Best regards,
