In Android webview if we want to run webview media even screen goes off then here is the top answer of the problem in java
public class MyWebView extends WebView {
public MyWebView(Context context) {
super(context);
}
public MyWebView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyWebView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@Override
protected void onWindowVisibilityChanged(int visibility) {
if (visibility != View.GONE) super.onWindowVisibilityChanged(visibility);
}
}
