Android. How to remove brakes in WebView when JavaScript function is used?

Question

JavaScript

Good afternoon!
I am writing an Android application and it has a WebView. Through the loadUrl() method, I call a JavaScript function that passes in my position and draws a marker.
It looks like this:

webView.post(new Runnable() {
            @Override
            public void run() {
                webView.loadUrl("javascript:send_location(" + x + ", " + y + ")");
            }
        });

I call this function every second, but over time, the performance of the View element (WebView) starts to go to zero. The application itself works correctly and all other elements of the application do not suffer in any way.
What could be the reason? Tried various ways to solve the problem, but they did not help.
P. S The application memory does not suffer, the marker is drawn once, and then it only moves.

Alternatively, you can try Crosswalk as a replacement for the standard WebView.
