Can anybody please guide me regarding how to launch my android application from the android browser?
For example, You have next things:
A link to open your app: http://example.com
The package name of your app: com.example.mypackage
Then you need to do next:
1) Add an intent filter to your Activity (Can be any activity you want. For more info check the documentation).
2) Create a HTML file to test the link or use this methods.
Open your Activity directly (just open your Activity, without a choosing dialog).
Open this link with browser or your programm (by choosing dialog).
3) Use Mobile Chrome to test
4) That's it.
And its not necessary to publish app in market to test deep linking =)
Also, for more information, check documentation and useful presentation.
