Don't enter mimeType below KitKat.

fun getMimeType(): String? {
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        "text/html; charset=utf-8"
    } else {
        null
    }
}
loadDAtaWithBaseURL(URL, "<html><h1>TEST</h1></html>", getMimeType(), "utf-8", null);

Java:

if(Build.VERSION.SDK_INT < 21)
    webView.loadDataWithBaseURL("about:blank","<html><h1>TEST</h1></html>","text/html", "UTF-8",null);
else
    webView.loadDataWithBaseURL("about:blank","<html><h1>TEST</h1></html>","text/html; charset=utf-8", "UTF-8",null);
