위젯이있는 Android 애플리케이션을 만들고 있습니다.구성 활동에서 appWidgetId를 가져 오는 데 문제가 있습니다.
이[편집] 그냥 명확하게하려고 : 번들 (intent.getExtras에서()가) 항상 널 내가 설정 활동 ... 우선을 만들기 시작까지 모든 것이 내 코드, 일하고 있었다. 나는 그것을 고치기 위해 무엇을해야합니까? [/ 편집]

그것은 항상 다른 이동 ... 그래서 모든 것은 오류없이 넘어 어쨌든
는, 문제는 여기에 보이고있다. :/내가해야 할 일이 있습니까? AndroidManifest.xml 또는 그와 비슷한 것을 변경해야합니까?
감사합니다.
피씨 : 음 ... 나는 안드로이드 개발에 절대적으로 새로운 ... 그래서, 이상한 일이 있다면, 알려주세요.
그래서 ... 어떤 일을? :/ –
