How to listen for a custom URI

Question

I am working on an application which has its own URI prefix. (dchub:// in this case)

Searching all over and read a lot but I got a bit confused.

Is it possible

Answer 1

To register a protocol in your android app, add an extra block to the AndroidManifest.xml.

<manifest>
 <application>
   <activity>
           <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="dchub"/>
            </intent-filter>
   </activity>
 </application>
</manifest>

Answer 2

Try this code:

try {
    Uri data = getIntent().getData();
    if (data.equals(null)) { 
    } else { 
        String scheme = data.getScheme();
        String host = data.getHost();
        int port = data.getPort(); 
        //type what u want
        tv.setText("any thing");
     }      
} catch (NullPointerException e) {
      // TODO: handle exception
  tv.setText("Null");
}

Don't use data.equals(null). That is bound to fail, you can't call methods on a null object, hence the NPE.

Why the emtpy code block? In my mind, this is a lot prettier:

if(data != null){
    // code here
}
