}

Demo

Usage

import ExpoPip from "expo-pip";
import { useState } from "react";
import { Button, StyleSheet, Text, View } from "react-native";

export default function App() {
  const { isInPipMode } = ExpoPip.useIsInPip();
  const [automaticEnterEnabled, setAutomaticEnterEnabled] = useState(false);

  return (
    <View style={styles.container}>
      <Text>{isInPipMode ? "In Pip Mode 😎" : "Not In Pip Mode"}</Text>
      {!isInPipMode && (
        <>
          <Button
            onPress={() =>
              ExpoPip.enterPipMode({
                width: 200,
                height: 300,
              })
            }
            title="Enter Pip Mode"
          />
          <Button
            onPress={() => {
              const newValue = !automaticEnterEnabled;
              setAutomaticEnterEnabled(newValue);
              ExpoPip.setPictureInPictureParams({
                autoEnterEnabled: newValue,
              });
            }}
            title={`Toggle automaticEnter: ${automaticEnterEnabled ? "on" : "off"}`}
          />
        </>
      )}
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: "#fff",
    alignItems: "center",
    justifyContent: "center",
  },
});

Custom PiP Actions

To use custom Picture-in-Picture actions, you must declare the icons in the plugin configuration inside your app.json.

// app.json
{
  "expo": {
    // ...
   "plugins": [
    // ..
      [
        "expo-pip",
        {
          "icons": [
            "./assets/play_pause.png",
          ]
        }
      ]
    ]
  }
}

Mapping iconName

Once the icons are registered in the plugin configuration, reference them using iconName property. The iconName must match the icon file name passed in the plugin configuration.

File Name	iconName Value
play_pause.png	"play_pause"

ExpoPip.setPictureInPictureParams({
  actions: [
    {
      iconName: "play_pause",
      action: "custom-play-pause-action",
      title: "Custom Play/Pause Action",
      description: "This is a description for the custom play/pause action",
    },
  ],
});

Listening to Custom Actions Press Event

useEffect(() => {
  const subscription = ExpoPip.addEventListener(
    "onPipActionPressed",
    (event) => {
      event.action; // custom-play-pause-action
    },
  );
  return () => subscription.remove();
}, []);

Icons recommendations

• Icons must be monochromatic white
• Transparent background
• Square image recommended
• 96×96px recommended resolution
• File name must:
  • Be lowercase
  • Use only letters, numbers and underscores
