간단한 웹뷰를 만들어봅니다
manifests->AndroidManifest.xml에서 추가시켜주자
- <application 행 위에 다음 한 행을 추가한다 - 인터넷 사용권한을 허용해주는 코드이다
<uses-permission android:name="android.permission.INTERNET"/>

package 부분은 개개인마다 다르므로 import 구문부터 복사하는 것을 권장한다
추가로 MainActivity이름도 다를 수 있기때문에 주의해서 복사하고, 복사보다는 직접 쳐보는 것을 권장하는 바이다
MainActivity.java
package com.example.boki.simplewebbrowser;

import android.os.Bundle;
import android.view.View;

import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
