Question

我正在android studio中开发一个网络应用程序，我有我的webview和一切正确设置。这个应用程序调试正常，直到最近的工作室更新。

我似乎在调试时遇到这个错误：

Error:(29, 6) Execution failed for task ':app:mergeDebugResources'.

C：\ Users \ khand_000 \ Desktop \ Android Projects \ QuadraticEquationSolver \ app \ src \ main \ res \ assets \ index.html：29：6：错误：元素类型＆＃34;输入＆＃34;必须由匹配的结束标记终止＆＃34;＆＃34;。

这是我的index.html：

<!doctype html>

<head>
    <meta charset="UTF-8"/>
    <style>
        input, select {
        width: 50px;

        border: 1px solid #000;
        height: 30px;
        text-align: center;
        }
        button {

Enter your Quadratic Equation in the form: <br />     <b>ax<sup>2</sup>+bx+c=0</b><br />
You may use negative values for a, b and c

            }
            });
    });
</script>

而且，作为一个注释，我已经在插件中禁用了AndroidLint。

错误：（29,6）错误：元素类型＆＃34;输入＆＃34;必须由匹配的结束标记终止＆＃34;＆＃34;
