For me, it is required to fill multiple entries in form one by one on callback of each "webView.evaluateJavascript" Note: API version > 18

See below snippet for reference

ArrayList arr = new ArrayList();
arr.add("document.getElementsByName(\"tag_name\")[0].value  = \"your_value\";");
.
.
.
call setValue(arr, 0)

private void setValue(final ArrayList arr, final int i) {
        if (i < arr.size()) {
            webView.evaluateJavascript(arr.get(i), new ValueCallback() {
                @Override
                public void onReceiveValue(String value) {
                    int j = i + 1;
                    setValue(arr, j);
                }
            });
        }else{
            webView.evaluateJavascript("document.getElementById(\"your_form_id\").submit();", new ValueCallback() {
                @Override
                public void onReceiveValue(String value) {
                    Toast.makeText(MainActivity.this, "Submitted: "+value, Toast.LENGTH_SHORT).show();
                }
            });
        }
    }
