Hi, I'm going to share some android OS command for you app. It's can help a lot to link to your Google Playstore page.

Think you just made a button and want to link it to your App's google playstore page.

All you have to do is just use this command:

market://details?gotohome=com.yourAppName

When a user click on the button, he will be redirected to your app's playstore page automatically.

You can get more information about market://details?gotohome=1 from here

Here’s another way you can do it:

From a web site:

http://play.google.com/store/search?q=pub:<publisher_name>

From an Android app:

market://search?q=pub:<publisher_name>
