expo-intent-filters-extension

Installation

npx expo install expo-intent-filters-extension

Description

This is an expo config plugin that provides granular control over android intent filters inside Expo's managed workflow. It provides the exact same interface as the typical android intent filters field in app.json/app.config.ts, but with the ability to specify exact actions and categories.

A key use case for this would be to enable NFC scans to deep link into your app. Currently, intent filters in app.json/app.config.ts do not support the required action: android.nfc.action.NDEF_DISCOVERED as it must follow android.intent.actions.ACTION_NAME.

Usage

{
  "expo": {
    ...
    "plugins": [
      [
        "expo-intent-filters-extension",
        {
          "intentFilters": [
            {
              "action": "android.nfc.action.NDEF_DISCOVERED",
              "autoVerify": true,
              "data": [
                {
                  "scheme": "https",
                  "host": "website.com",
                  "pathPrefix": "/profile"
                }
              ],
              "category": ["android.intent.category.DEFAULT"]
            }
          ]
        }
      ]
    ]
  }
}

Which in turn creates intent filters in AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="expo.modules.intentfiltersextension.example">
      ...
      <intent-filter android:autoVerify="true" data-generated="true">
        <action android:name="android.nfc.action.NDEF_DISCOVERED"/>
        <data android:scheme="https" android:host="website.com" android:pathPrefix="/profile"/>
        <category android:name="android.intent.category.DEFAULT"/>
      </intent-filter>
      ...
</manifest>
