Answer

Put this code into your manifest in your activity tag :

    <intent-filter tools:ignore="AppLinkUrlError">
        <action android:name="android.intent.action.VIEW" />

        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />

        <data android:mimeType="video/*" />
    </intent-filter>

It will show your app into a suggestion list whenever user selects a video file from his phone. ALthough, you need to handle the further actions in your videoplayer activity.

Because this tag will only help you getting your into a suggestion list, to play a selected video, you have to use intent to get the selected video uri. You can find the examples of playing a video file like this on the internet easily.
