Seems you did NOT understand what the result of "going through the link" is. Did you go to the linked webpage and do you have created a custom style file with help of the site. And you have added this theme to your app?
What let you think you need to use a "custom Manifest"? There is only ONE Manifest for each app but yes, it must be slightly changed. There are tutorials about it when you search for them
I tried-n-tried to apply customised theme but no success..
I might be missing something simple step..
I just created another top panel n similar to title n used . Here I can easily add another views, change color/text..
Bottom line is I got which i want...
