java.sql.SQLException：android studio中没有合适的驱动程序

Question

这是我实现的代码，只想插入一个字段而不是其他两个字段 我想使用jdbc方法而不是volley方法在mysql数据库中插入数据 我把这段代码放在doInBackground函数中 当我单击按钮时，它显示错误，但应用程序不崩溃

    public class MainActivity extends AppCompatActivity {
        EditText email,username,password;
        Button insert;
        TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        email=(EditText)findViewById(R.id.email);
        username=(EditText)findViewById(R.id.username);
        password=(EditText)findViewById(R.id.password);
        insert=(Button)findViewById(R.id.insert);
        textView=(TextView)findViewById(R.id.tv);
    }

    public void insert(View view) {
        Send send=new Send();
        send.execute("");
    }

    private class Send extends AsyncTask<String,String,String> {
        String msg="";
        String Email=email.getText().toString();
        // String User=username.getText().toString();
        //String Pass=password.getText().toString();

        @Override
        protected void onPreExecute() {
            //super.onPreExecute();
            textView.setText("please wait inserting data ");

        }

        @Override
        protected String doInBackground(String... strings) {

            try{
                Class.forName("com.mysql.jdbc.Driver").newInstance();
               // Connection con= DriverManager.getConnection("jdbc:mysql://127.0.0.1:81/check","root","");
                Connection con=(Connection) DriverManager.getConnection("http://192.168.10.12:81/check","check123","123");
                if(con==null)
                {
                    msg="connection goes wrong ";
                }
                else
                {
                    //String query="insert into registration (id,email,username,password) values ('"+Email+"','"+User+"','"+Pass+"')";
                    String query="insert into test (name) values ('"+Email+"')";
                    Statement stmt=con.createStatement();
                    stmt.executeQuery(query);
                    msg="insert success ";
                }
                con.close();
            }
            catch (Exception e)
            {
                msg="connection goes wrong ";
                e.printStackTrace();
            }
            return msg;
        }

        @Override
        protected void onPostExecute(String s) {
            //super.onPostExecute(s);
            textView.setText(msg);
        }
    }
}

  

我已经包含了jdbc驱动程序编译项目（'：mysql-connector-java-3.0.17-ga-bin'）

错误由android studio显示
