I am creating a Browser App but Android won't detect my app in chooser while I click on any URL

I am creating a Browser app and I want Android to treat my app as a browser and show up in the app chooser to open with.

I want my app to show up in this list.

Here is my manifest Activity code:

<activity
        android:name=".Activity.LinkDetectorActivity"
        android:exported="true"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <intent-filter>
            <data android:scheme="testscheme" />
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.BROWSABLE" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

Replace your intent-filter with below,

 <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="http"/>
        <category android:name="android.intent.category.DEFAULT" />
        <!-- The BROWSABLE category is required to get links from web 
        pages. -->
        <category android:name="android.intent.category.BROWSABLE" />
 </intent-filter>

</activity>
