I started a public code repository for the art viewer application template, currently updating comments.
You can use this template for commercial or non commercial usage, replacing assets with your own assets and having a license to use those assets is required in case Google Play asks for a license. You will need to start your own google play dev account 25.00 and an adMob account if you wish to include ads.
I ended up working harder when i started making it worth something (ad revenue for viewing my art) as opposed to my art hobby as hobby. Put yourself out there and fight the criticism self and all around...!
You will have to customize it a bit to make it unique and different than similar ones on google play, icons, music, artowork of course, and the page turn animations. These are the simplest one's and with a quick Google you can see how to create your own animations. Its easy to make your own really : )
You can donate to help continue art applications and code repositories, as well as guides I make if you like or if you made a sizable profit from it but not necessary.
