Configuration

Android 11+ and iOS 9+ only let your app ask about apps you’ve declared ahead of time. This is an operating-system rule, not a limit of this library. List every app you plan to check.

With the config plugin (recommended)

{
  "expo": {
    "plugins": [
      [
        "expo-check-installed-apps",
        {
          "android": ["com.facebook.katana", "com.twitter.android", "com.whatsapp"],
          "ios": ["fb", "twitter", "whatsapp"]
        }
      ]
    ]
  }
}

Option	Type	What it does
`android`	`string[]`	Adds a `<package android:name="…" />` entry inside `<queries>` in `AndroidManifest.xml` for each package name.
`ios`	`string[]`	Adds each scheme to `LSApplicationQueriesSchemes` in `Info.plist`. `fb://` and `fb:` are trimmed to `fb`.

Entries are trimmed and de-duplicated, and existing entries in your manifest or plist are kept. See the config plugin reference for details.

Using app.config.js? Same shape:

export default {
  expo: {
    plugins: [
      [
        'expo-check-installed-apps',
        { android: ['com.whatsapp'], ios: ['whatsapp'] },
      ],
    ],
  },
};

Add a <queries> block directly inside <manifest>:

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
  <queries>
    <package android:name="com.facebook.katana" />
    <package android:name="com.twitter.android" />
    <package android:name="com.whatsapp" />
  </queries>

  <!-- rest of your manifest -->
</manifest>

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>fb</string>
  <string>twitter</string>
  <string>whatsapp</string>
</array>
