I have tested this app on the Android emulators, phones, tablets, and Google TV. Its works. When I published it Google Play, the app is not visible. Below is the manifest
Here is my first hand experience. I published my first app on the Google play store (GPS) on October 15th. Was pretty excited to locate on GPS. But yes the same experience, it didn't show up.
Then here is the series of events: 1. Day 1 to Day 3 When searched using double quotes "Cool Tic Tac Toe", I could see at the bottom of the search list - at the last almost after 200 items, but yes it was there which made me happy.
2. Day 4 onwards - I removed the quotes and searched by app name with the spaces i.e. Cool Tic Tac Toe, it showed up almost at the bottom. In the mobile or tablet version of Play Store app, you will see filters like "New" "4.5" or "4.0" for ratings. So when I used the filters New and 4.5 in the play store app, it started showing up almost in the first few pages.
3. Day 6-7 My app now shows up at the top (in top 10) when I put the exact app name without any quotes and without using any filters - this is very good sign. So far I have about 100 downloads (most from my friends and family and not from any real user I would imagine as no one in the world will really search my app with its full name.
I realize visitors of GPS would not know my app name, they will search with a generic key word like Tic Tac Toe and not Cool Tic Tac Toe
Day 7 onwards - today(8th day) I search my app with generic name Tic Tac Toe in GPS, it doesn't show up ANYWHERE, not even at the bottom. This is a little disappointing, but I do hope it will crawl up and start showing somewhere. HOWEVER If I add the filters "New" and "4.5" it does show up in top 25. This I think is a good sign. I will update more on this if I see any related behavior.
Hope this helps give some idea to my fellow developers who have put their first app in GPS and trying to locate it in the ocean of many millions of other apps.
