expo-call-detector

Detect phone call states in your Expo app.

Installation

npx expo install expo-call-detector

API

useCallDetector()

Hook that automatically starts call detection and manages state.

import { useCallDetector } from "expo-call-detector";
import ExpoCallDetectorModule from "expo-call-detector";
import { useEffect } from "react";

export default function App() {
  const { isCallActive, isReady } = useCallDetector();

  useEffect(() => {
    ExpoCallDetectorModule.requestPermission();
  }, []);

  return <Text>{isCallActive ? "On Call" : "No Call"}</Text>;
}

Manual Control

import ExpoCallDetectorModule from "expo-call-detector";

// Check/request permission
const hasPermission = await ExpoCallDetectorModule.checkPermission();
const permission = await ExpoCallDetectorModule.requestPermission();

// Start/stop listening
await ExpoCallDetectorModule.startListening();
await ExpoCallDetectorModule.stopListening();

// Listen to events
const subscription = ExpoCallDetectorModule.addListener(
  "onCallStateChanged",
  (event) => {
    console.log("Call active:", event.isActive);
  }
);

Permissions

Android

The READ_PHONE_STATE permission is automatically added by this module. Users will need to grant permission at runtime using the requestPermission() method.

iOS

No special permissions required. Uses CallKit for call state detection.
