How do I launch my app when a user downloads a file from browser?

Question

I'm trying to make a custom downloader UI for Android, and I was hoping there was a configuration I could set in my apps manifest to allow other apps like chrome to automatically open my app when a file of any downloadable type begins to download.

Ideally just replacing the Android downloader would be the goal here.

I'd really appreciate any pointers!

You will have to use the intent filters in your activity tag like below:

 <activity android:label="@string/app_name" 
            android:launchMode="singleTop" 
            android:name=".DownloadActivity">
        <intent-filter>
            <action android:name="android.intent.action.VIEW"/>
            <category android:name="android.intent.category.BROWSABLE"/>
            <category android:name="android.intent.category.DEFAULT"/>
            <data android:scheme="http"/>
            <data android:scheme="https"/>
            <data android:scheme="ftp"/>
            <data android:scheme="sftp"/>
            <data android:mimeType="image/*"/>
            <data android:mimeType="video/*"/>
            <data android:mimeType="audio/*"/>
            <data android:mimeType="text/plain"/>
        </intent-filter>

        <intent-filter>
            <action android:name="android.intent.action.VIEW"/>
            <category android:name="android.intent.category.BROWSABLE"/>
            <category android:name="android.intent.category.DEFAULT"/>
            <data android:scheme="http"/>
