How to disable cache WebView?

Question

Android

Good afternoon!
In my project I am using a WebView to display information. Here is a code snippet:

String mainBody = getIntent().getStringExtra(EXTRA_MAIN_BODY_TEACH);
        WebView webView = findViewById(R.id.wv_teach_info);
        webView.getSettings().setAppCacheEnabled(false);
        webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
        webView.loadDataWithBaseURL(null, mainBody, "text/html", "UTF-8", null);

To disable the cache, I use lines 3 and 4, but this code does not get rid of caching.
What am I doing wrong? How to disable the cache?
Thank you!
