Android Webview freeze on lock screen

I am working with audio website for webview app, problem is the app freezes when phone screen is lock is on due to the onPause method i am using:

public void onPause() {
    super.onPause();
    mWeb.onPause();
    mWeb.loadUrl("about:blank");
}

Now if I don't use mWeb.loadUrl("about:blank");, then the music keeps running in background

If I use it and the phone goes in sleep mode, the app freezes

How can I solve this where app should not freeze when the lock screen shows and also so the music does not play when the app is closed?

I used pauseTimers() method to stop video/audio from playing in the background in the onPause() method of the activity.And then in onResume() method I used resumeTimers() and WebView.onResume() method to webview freezing. Also, I'd suggest don't use "about:blank" in onPause() instead in onDestroy() method of the activity. Here's my complete implementation:

@Override
protected void onPause() {
    super.onPause();
    stopVideo();
    webview.pauseTimers();
}

@Override
public void onResume() {
    super.onResume();
    webview.resumeTimers();
    webview.onResume();
}

private void stopVideo() {
    try {
        Class.forName("android.webkit.WebView")
                .getMethod("onPause", (Class[]) null)
                .invoke(webview, (Object[]) null);
    } catch (Exception e) {
        e.printStackTrace();
    }
}
@Override
    protected void onDestroy() {
        super.onDestroy();
        webview.loadUrl("about:blank");
        webview.destroy();
        webview = null;
    }
