I built a phonegap app that is simply an launcher to a website. You download the app, click on it, and it will open up your web browser at a specific url.
People with android phones see this app in the Google Play market. People with Samsung Galaxy Tab do not see this app in the Google Play Market. How do I make this app accessible to people with Galaxy Tab?
As I commented, AndroidManifest file of your app does supply information like required screen size for the app, minimum DPI, etc. You may need to set those values to match screensizes of Tablets, and then it'll show up in Play Store for tablets as well.
