# Create Custom manifest Variables

```gradle
android {
    defaultConfig {
        manifestPlaceholders = [hostName:"www.example.com"]
    }
    ...
}
```

Now you can use `hostname` as:

```
<intent-filter ... >
    <data android:scheme="https" android:host="${hostName}" ... />
    ...
</intent-filter>
```
