Q: How to add my browser in the default browser selection list in android? I have a app called "TextOnly" ..How to add in the list to select default browser?

A: Specify your intent in the android manifest file such as:
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="http"/> 
</intent-filter>

make sure:
<uses-permission android:name="android.permission.INTERNET"></uses-permission>

is in there too.
reference: 

Similarly, if the action is ACTION_VIEW and the data field is an http: URI, the receiving activity would be called upon to download and display whatever data the URI refers to.
