Android 에뮬레이터에서 내 앱을 실행하려고 할 때마다 내 애플리케이션이 표시되지 않습니다. 나는 이것을 얻고있다 error 그러나 나는 그것을 해독하는 데 어려움을 겪고있다. 에뮬레이터에서 내 앱을 볼 수 있도록 어떻게 수정하면 되나요? 코드 줄이 엉망이되는 것과 관련이 있다고 생각하지만 어디에 위치 할 수는 없습니다.내 응용 프로그램이 에뮬레이터에서 작동하지 않는 이유는 무엇입니까?

여기 MainActivity.java의 다음 error

에게 Toolbar 요소 :

android:minHeight="@style/ThemeOverlay.AppCompat.Dark.ActionBar"

스타일 참조 치수로 변환 할 수있는 일이 내가 왼쪽 따라서 예외

Caused by: java.lang.UnsupportedOperationException: Can't convert value at index 37 to dimension: type=0x1 
at android.content.res.TypedArray.getDimensionPixelSize(TypedArray.java:730) 
... 
at android.support.v7.widget.Toolbar.<init>(Toolbar.java:231) 
... 
at com.navi.navi.MainActivity.onCreate(MainActivity.java:15)

아니다 stacktrace의 가장 중요한 부분.

스타일 리소스를 참조하려는 경우 style 속성을 사용하십시오. android:minHeight을 설정하려는 경우 40dp 또는 @dimen/something 참조와 같은 2 진 값을 사용하십시오.
