### Android Expansion File Usage

Within your render function, assuming you have a file called

"background.mp4" in your expansion file. Just add your main and (if applicable) patch version

```

<Video

  source={{uri: "background", type: "mp4", mainVer: 1, patchVer: 0}}

/>

Expansions files allow you to ship assets that exceed the 100MB apk size limit and don't need to be updated each time you push an app update.

This only supports mp4 files and they must not be compressed. Example command line for preventing compression:

```bash

zip -r -n .mp4 *.mp4 player.video.example.com

```

This will look for an .mp4 file (background.mp4) in the given expansion version.

```javascript

// Within your render function, assuming you have a file called

// "background.mp4" in your expansion file. Just add your main and (if applicable) patch version

<Video source={{uri: "background", mainVer: 1, patchVer: 0}} // Looks for .mp4 file (background.mp4) in the given expansion version.

       resizeMode="cover"           // Fill the whole screen at aspect ratio.

       style={styles.backgroundVideo} />
