AppCompat는 런처 위젯 기능을 중단합니다. "오류보기를 사용하여 어떤보기도 찾을 수 없습니다."

Question

저는 실행기 개발자이며 위젯에 대한 기초는 항상 내가 찾은이 간단한 안내서를 따라 왔습니다 : Hosting Android Widgets. 이제이 방법은 데모 앱을 사용할 때 100 % 작동합니다. 문제는 AppCompat 테마를 추가하고 의 최신 com.android.support:appcompat-v7:25.1.1이 아닌 AppCompatActivity을 확장하자마자 문제가 발생합니다. 또한

AppWidgetHostView 표시 "Couldn't add widget" 다음과 같이 ACTION_APPWIDGET_PICK 대화 상자에서 특정 위젯을 선택하면, 나는 오류가 발생합니다. 오류 로그에 따라 당연히 WidgetHostExampleActivity.java line #129을 살펴 보 겠지만 간단히 mAppWidgetHost.createView(this, appWidgetId, appWidgetInfo);을 호출하는 것입니다.

코드는 appcompat-v7:22.1.1에서 작동하지만 그 이상은 작동하지 않는 것 같습니다.

참고 :

1. 나는 시험과 Android 5.0.2 및 Android 7.1.1이 일부 위젯이 발생
2. 에이 오류를 확인했다. 실패한 일부는 Default Calendar app은 Android 7.1.1이고 Play - My Library은 플레이 스토어 위젯입니다. 난 아직도

추신 : 나는 지금 당장 질문을 게시하지 않으므로 내가 할 때 그것이 진짜 문제라는 것을 알고 있습니다.

Answer 1

관리자 및 호스트의 컨텍스트를 활동 컨텍스트가 아닌 응용 프로그램 컨텍스트로 변경하십시오.

AppWidgetManager = AppWidgetManager.getInstance(getApplicationContext()); 
mAppWidgetHost = new AppWidgetHost(getApplicationContext(), APPWIDGET_HOST_ID); 

그 문제가 해결되었습니다.
