WebView not working for Capture Image from Camera Or Select Image from gallery

Question

I'm loading one URL in WebView, the URL page contains functionality of capturing image from device camera OR select image from gallery. If I open URL in Browser, everything works fine but, if I open the same URL in WebView then Camera and Gallery functionality do not works. I think I'm missing some WebView setting. Please check my below code and help me to solve my problem.

Below is my WebViewActivity--

public class WebViewActivity extends AppCompatActivity
{
    WebView myWebView;
    ProgressBar myProgress;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my_webview);
        findViews();
    }

    private void findViews()
    {
        myWebView= (WebView) findViewById(R.id.myWebView);
        myProgress= (ProgressBar) findViewById(R.id.myProgress);
        myWebView.setWebViewClient(new myWebClient());
        myWebView.getSettings().setJavaScriptEnabled(true);
        myWebView.getSettings().setLoadWithOverviewMode(true);
        //Other webview settings
        myWebView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
        myWebView.setScrollbarFadingEnabled(false);
        myWebView.getSettings().setBuiltInZoomControls(true);
        myWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
        myWebView.getSettings().setAllowFileAccess(true);
        myWebView.getSettings().setSupportZoom(true);

        myWebView.loadUrl(SafeNestConstants.MEDLIFE_URL);
    }

    public class myWebClient extends WebViewClient
    {
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon)
        {
            // TODO Auto-generated method stub
            super.onPageStarted(view, url, favicon);
        }

        @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
        public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request)
        {
            myProgress.setVisibility(View.VISIBLE);
            view.loadUrl(request.getUrl().toString());
            return true;
        }
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url)
        {
            // TODO Auto-generated method stub
            myProgress.setVisibility(View.VISIBLE);
            view.loadUrl(url);
            return true;

        }

        @Override
        public void onPageFinished(WebView view, String url)
        {
            // TODO Auto-generated method stub
            super.onPageFinished(view, url);
            myProgress.setVisibility(View.GONE);
        }
    }
}

Below is my activity_my_webview.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_terms_and_conditions"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.mypackage.WebViewActivity">

    <WebView
        android:id="@+id/myWebView"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </WebView>

    <ProgressBar
        android:id="@+id/myProgress"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:indeterminateDrawable="@drawable/progress_medium"
        android:visibility="visible" />
</RelativeLayout>

Also let me know if I can provide more information for the same. Thank you.
