안드로이드 WebView 대신 Chrome Tab 사용

간단한 웹 브라우징 기능에 대해서는 WebView 대신 Chrome Tab 기능도 사용할 수 있어 소개 한다 

최신 안드로이드 폰에서는 크롬이 강제적으로 설치되어 있어서 무난하게 사용할 수 있을것이다

support 라이브러리에 맞는 버젼으로 build.gradle에 추가 

implementation 'com.android.support:customtabs:28.0.0'

여러가지 방법으로 CustomTab을 사용이 가능하지만 몇가지 이벤트를 전달받을 수 있도록 

 ServiceConnection 부분으로 사용한다 

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        CustomTabsClient.bindCustomTabsService(
                getApplicationContext() ,
                "com.android.chrome",
                tabConnection);
    }

tabConnection 구현

 private CustomTabsServiceConnection tabConnection = new CustomTabsServiceConnection() {
     
 
        @Override
        public void onCustomTabsServiceConnected(ComponentName componentName, CustomTabsClient customTabsClient) {
            CustomTabsSession session = customTabsClient.newSession(null);
 
            CustomTabsIntent.Builder customTabsIntentBuilder =
                    new CustomTabsIntent.Builder(session);
 
            CustomTabsIntent customTabsIntent = customTabsIntentBuilder.build();
            customTabsIntent.intent.setPackage("com.android.chrome");
            customTabsIntent.intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            customTabsIntent.launchUrl(getApplicationContext(), Uri.parse("https://psbs.tistory.com"));
 
        }
 
        @Override
        public void onServiceDisconnected(ComponentName name) {
 
        }
    };

새로운 크롬과의 연결 session을 만들어서 launchUrl을 하는 방식으로 웹페이지 호출이 가능하다 

로드 시작 이벤트, 로드 끝 이벤트를 받고 싶다면 newSesson으로 넣는 null 대신 CustomTabsCallback을 호출하는것으로 가능한데 

            CustomTabsSession session = customTabsClient.newSession(new CustomTabsCallback(){
                @Override
                public void onNavigationEvent(int navigationEvent, Bundle extras) {
                    super.onNavigationEvent(navigationEvent, extras);
                    switch (navigationEvent) {
                        case CustomTabsCallback.NAVIGATION_STARTED:
                            Log.d("psbs", "NAVIGATION_STARTED");
                            break;
                        case CustomTabsCallback.NAVIGATION_FINISHED:
                            Log.d("psbs", "NAVIGATION_FINISHED");
                            break;
                        case CustomTabsCallback.NAVIGATION_FAILED:
                            Log.d("psbs", "NAVIGATION_FAILED");
                            break;
                        case CustomTabsCallback.NAVIGATION_ABORTED:
                            Log.d("psbs", "NAVIGATION_ABORTED");
                            break;
                    }
                }
            });

위의 session 생성을 이것으로 대체하는것으로 이벤트를 확인 가능해진다 

CustomTab의 메뉴 등을 추가를 위해서는 다음과 같은 코드로 추가/이벤트 핸들링이 가능하다 

String menuItemTitle = "my menu";
            Intent actionIntent = new Intent(
                    getApplicationContext(), MainActivity.class);
            PendingIntent menuItemPendingIntent = PendingIntent.getActivity(
                    getApplicationContext(), 1, actionIntent, 0);
