Can anybody please guide me regarding how to launch my android application from the android browser?
Look @JRuns answer in here. The idea is to create html with your custom scheme and upload it somewhere. Then if you click on your custom link on your html-file, you will be redirected to your app. I used this article for android. But dont forget to set full name Name = "MyApp.Mobile.Droid.MainActivity"
attribute to your target activity.
