설치 후 위젯이 나타나지 않음

배터리 위젯을 시험하고 있지만 설치 후 나타나지 않습니다. 이 문제에 대한 다른 게시물에서 언급 한 모든 솔루션을 시도했습니다. 매니 페스트에 더미 활동을 추가했습니다. 하지만 액티비티는 시작되지만 위젯은 표시되지 않습니다. 내가 말한 것 이외의 다른 곳으로 연결해야합니까? 여기 설치 후 위젯이 나타나지 않음

에게 있습니다 활동은 방금 시작되었지만 위젯은 내 경우.

구현 방법을 나타내는 코드가 없으면 위젯이 작동하지 않는 이유를 알 수 없습니다. –

첫 번째 읽기이 :

http://developer.android.com/guide/topics/appwidgets/index.html이 또한 내가 매니페스트에 위젯에 대한 기록을 볼 수 없습니다.

@Andrew Cumming : 죄송합니다. 이제 내 게시물을 편집하고 전체 코드를 추가했습니다. 한번 봐주세요. – Atihska

제 수정 된 코드를 보시기 바랍니다. – Atihska

1. 레이아웃보기가 지원되지 않습니다. – Aleksandr
