Live web screen recording Android app development

Creating a high-quality live web screen recording Android application can be a complex task that involves multiple components and technologies. Here is a sample code that uses the MediaProjection API and the WebRTC library to record and stream the device screen and audio to a server in real-time:

Here the example of a code to create a  application 

public class MainActivity extends AppCompatActivity {

    private static final int REQUEST_CODE = 1;

    private MediaProjectionManager mProjectionManager;

    private MediaProjection mMediaProjection;

    private VirtualDisplay mVirtualDisplay;

    private Surface mSurface;

    private EglBase mEglBase;

    private PeerConnectionFactory mPeerConnectionFactory;

    private VideoSource mVideoSource;

    private AudioSource mAudioSource;

    private VideoTrack mVideoTrack;

    private AudioTrack mAudioTrack;

    private PeerConnection mPeerConnection;

    private MediaStream mMediaStream;

    private WebSocket mWebSocket;

    private Executor mExecutor;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        // Initialize the MediaProjectionManager

        mProjectionManager = (MediaProjectionManager) getSystemService(Context.MEDIA_PROJECTION_SERVICE);

        // Request screen capture permission

        startActivityForResult(mProjectionManager.createScreenCaptureIntent(), REQUEST_CODE);

        // Initialize the PeerConnectionFactory

        PeerConnectionFactory.initialize(PeerConnectionFactory.InitializationOptions.builder(this).createInitializationOptions());

        mPeerConnectionFactory = new PeerConnectionFactory();

        // Initialize the Executor

        mExecutor = Executors.newSingleThreadExecutor();

        // Initialize the WebSocket

        mWebSocket = new WebSocketFactory().createSocket("ws://example.com/");

        // Initialize the EGL context

        mEglBase = EglBase.create();

        // Initialize the Surface

        SurfaceViewRenderer renderer = findViewById(R.id.renderer);

        renderer.init(mEglBase.getEglBaseContext(), null);

        renderer.setZOrderMediaOverlay(true);

        mSurface = renderer.getSurface();

        // Initialize the MediaStream

        mMediaStream = mPeerConnectionFactory.createLocalMediaStream("stream");

        // Initialize the VideoSource and VideoTrack

        mVideoSource = mPeerConnectionFactory.createVideoSource(false);

        mVideoTrack = mPeerConnectionFactory.createVideoTrack("video", mVideoSource);

        mVideoTrack.addSink(renderer);

        // Initialize the AudioSource and AudioTrack

        mAudioSource = mPeerConnectionFactory.createAudioSource(new MediaConstraints());

        mAudioTrack = mPeerConnectionFactory.createAudioTrack("audio", mAudioSource);

        // Add the VideoTrack and AudioTrack to the MediaStream

        mMediaStream.addTrack(mVideoTrack);

        mMediaStream.addTrack(mAudioTrack);

        // Initialize the PeerConnection

        mPeerConnection = mPeerConnectionFactory.createPeerConnection(new ArrayList<>(), new PeerConnection.Observer() {

            @Override

            public void onSignalingChange(PeerConnection.SignalingState signalingState) {}

            @Override

            public void onIceConnectionChange(PeerConnection.IceConnectionState iceConnectionState) {}

            @Override

            public void onIceConnectionReceivingChange(boolean b) {}

            @Override

            public void onIceGatheringChange(PeerConnection.IceGatheringState iceGatheringState) {}

            @Override

            public void onIceCandidate(IceCandidate iceCandidate) {}

            @Override

            public void onIceCandidatesRemoved(IceCandidate[] iceCandidates) {}

            @Override

            public void onAddStream(MediaStream mediaStream) {}

            @Override

            public void onRemoveStream(MediaStream mediaStream) {}

            @Override

            public void onDataChannel(DataChannel dataChannel) {}

            @Override

            public void onRenegotiationNeeded() {}

            @Override

            public void onAddTrack(RtpReceiver rtpReceiver, MediaStream[]

Here follow all steps and try it.
