필자는이 튜토리얼을 사용하여 내 프로젝트에 내 세로/가로 세그먼트를 해결하기 위해 노력 : http://www.cs.dartmouth.edu/~campbell/cs65/lecture09/lecture09.html응용 프로그램 충돌이
모든 것이 잘 (가로 및 세로 모두)를 작동하는 것 같다,하지만 오류

오 남자 SOOO 감사합니다! 그게 해결 됐어! 방금 manifest에있는 앱의 해당 부분에 대한 두 가지 액티비티 클래스에 configChange를 추가했습니다. – svennand
아니요, 대답을 수락하기 위해 기다렸다가 그 중 하나를 선택해야했습니다. 그 다음에 나는 upvote하려고했지만 충분한 "포인트"voteup 15 뭔가 평판 뭔가, -1 단지 .... wtf로 변경된 다음 일이 필요 없다는 오류가있어! – svennand
여전히 "투표 업은 15 평판이 필요합니다"라는 빨간색 배너와 동일한 오류가 발생하면 숫자는 0으로 돌아가고 -1로 되돌아갑니다. Facepalm, stackoverflow 내 첫 경험을 어디에 책상에 머리를 두드리는없이 내 문제에 대한 정말 깨끗하고 간단한 수정을 얻을.그리고 괴물 "고마워요"시스템이 나를 도청하고 있습니다 ... – svennand
