Android Intent ACTION_VIEW 웹 페이지 url 연결

 

Activity에서 다른 Activity를 호출할 때 Intent를 이용하여 화면전환을 하는 것과 같이 핸드폰에 기본적으로 장착된 App의 Activity를 호출 하는 경우에는 Intent의 action 중 ACTION_VIEW를 이용하여 웹 브라우저를 호출하는 방법 입니다.
기본 브라우저를 이용하여 웹 페이지 URL을 연결하려면 public Intent (String action, Uri uri) 메소드를 사용하는데 action 부분에는 ACTION_VIEW를 입력하고 Uri는 웹 주소를 입력하면 됩니다.

 

Intent intentUrl = new Intent(Intent.ACTION_VIEW, Uri.parse("https://copycoding.tistory.com/")); startActivity(intentUrl);

 

URL에 파라미터를 추가해서 넘기려면 URL 뒤에 붙여주도록 합니다.

 

String param = "/47"; Intent intentParam = new Intent(Intent.ACTION_VIEW, Uri.parse("https://copycoding.tistory.com/" + param)); startActivity(intentParam);

 

인터넷을 사용해야 하므로 Manifest에 permission을 추가해 주면 됩니다.
<uses-permission android:name="android.permission.INTERNET" />

 

버튼을 누르면 첫화면으로 이동 하고 param을 붙인경우 페이지를 찾아 갑니다.
