Yes you can get the data but you might need this in your manifest if you are doing implicit intents...
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="http"/>
</intent-filter>
And then if you want the data to make a new URL do this inside you activity:
Uri data = this.getIntent().getData();
url = new URL(data.getScheme(), data.getHost(), data.getPath());
