PIP (Picture-In-Picture) Mode

100ms React Native SDK provides support for creating Picture in Picture mode experience for video calls.

PIP Mode lets the user watch the room video in a small window pinned to a corner of the screen while navigating between apps or browsing content on the main screen.

Currently this functionality is only available on Android.

Minimum Requirements

  • Minimum version required to support PiP is Android 8.0 (API level 26)
  • Minimum react-native-hms SDK version required is 1.0.0

How to add PiP support

  1. You need to update the activity tag in the AndroidManifest.xml
<activity .... android:supportsPictureInPicture="true" android:configChanges="keyboard|keyboardHidden|orientation|screenSize|smallestScreenSize|screenLayout|uiMode" ... />
  1. Call enablePipMode method on "HMS Instance" when you want to start PIP mode.
// You can also check if PIP is supported on device or not. const isPIPSupported = await hmsInstance.isPipModeSupported(); const isEnabled = await hmsInstance.enablePipMode(); if (isEnabled) { // App has entered into PIP Mode setPIPModeActive(true); }

You can also add aspectRatio for Picture in Picture window.

... const isEnabled = await hmsInstance.enablePipMode({ aspectRatio: [16, 9] }); ...

Pip mode resizes your whole activity to a small container. So, you should hide the content that you don't want to show.

  1. Detect when App goes to "fullscreen" from PIP mode
import { AppState, AppStateStatus } from 'react-native'; ... const appStateRef = useRef(AppState.currentState); useEffect(() => { // We will register an AppState listener when App is in PIP Mode if (pipModeActive) { appStateRef.current = AppState.currentState; const appStateListener = (nextAppState: AppStateStatus) => { if ( appStateRef.current.match(/inactive|background/) && nextAppState === "active" ) { // Now, App is not in PIP mode setPIPModeActive(false); } appStateRef.current = nextAppState; }; AppState.addEventListener('change', appStateListener); return () => { AppState.removeEventListener('change', appStateListener); } } }, [pipModeActive]);

Example of showing content when App is in PIP Mode

// Getting trackId to show in PIP mode // getPreferredTrackId function returns trackId of preferred video track const pipTrackId = getPreferredTrackId() ... // If PIP mode is active, showing only single peer if (isPipModeActive) { return ( <HmsView ... trackId={pipTrackId} ... /> ) } // Showing tiles for all the peers return <MultiplePeers /> ...
