안드로이드 어떻게 URL을 누르십니까? 내가 원하는대로 밖으로 개방 브라우저

Question

try { 
    URL myURL = new URL("myURL that works fine on browser"); 
    URLConnection myURLConnection = myURL.openConnection(); 
    myURLConnection.connect(); 
} catch (MalformedURLException e) { 
    // new URL() failed 
    // ... 
} catch (IOException e) { 
    // openConnection() failed 
    // ... 
} 

으로이 간단한 HIT이는 this의 중복입니다

같은 eroor 더 AsyncTask를하거나 AsyncTask

Answer 1

사용을 구문 분석을 줘 없습니다. 정적 인 내부 클래스로 만들 수도 있고, 완전한 자체 클래스로 만들 수도 있습니다. try/catch 등을 추가해야하지만 정상적으로 작동합니다.

URL myURL = new URL("myURL that works fine on browser"); 
new UrlPinger(myUrl).execute(); 

class UrlPinger extends AsyncTask<URL,Void,Void> { 
    @Override 
    protected Void doInBackground (URL ... urls) { 
     URLConnection myURLConnection = urls[0].openConnection(); 
     myURLConnection.connect(); 
     return null; 
    } 
}
