이제 내가하고 싶은 일은 모든 것을 서비스에 넣어 백그라운드에서 작동하도록하는 것입니다. onCreate() 또는 onStart() 메서드에 Service 코드를 넣어야합니까? 핸들러와 다른 스레드를 사용하기 때문입니다. 내가 Activity에로 WebView를 사용할 수 없기 때문에 내가 URL 또는 HttpClient를 함께 이제 웹 사이트를 호출 할 때이처럼 내 로그 캣 내 실수를 제공합니다 내가 할 수 있도록

가 어떻게 서비스에서 GPS 위치를 부르죠 10-15 점이 아니라 단 한 점을 얻으시겠습니까? 나는 Activity에서 sqlite 데이터베이스에 데이터를 넣고 나중에 스레드의 마지막 행을 가져 와서 원에서 다른 행을 삭제하는 등의 작업을 수행했습니다. GPS 위치를 호출하고 백그라운드에서 웹 사이트로 전송하는 더 좋은 방법이 있습니까?

문제는 GPS 코드와 관련이 없습니다. 문제는 커서에서로드하려는 URL이 올바르지 않다는 것입니다. 'w.loadUrl'의 인수를 게시하십시오. – hwrdprkns
이것은 내가 웹 대신 w.loadurl –
의 서비스 http://www.compensatemeonline.com/truckmeonline/TruckMeOnline/UnosLokacijaSaTelefona.php?id="+mojsadrzaj+"&longitude="+longitude+"&latitude="+latitude+에서 사용하는 것입니다 "& brzina ="+ speed + "& vreme ="+ cal.getTime() + "& datum ="+ 날짜 + "& zauzetost ="+ zauzetost 이들은 브라우저에서 인쇄하여 사용하는 변수이며 결과는 –
