Answer 1

Caused by: java.lang.NullPointerException at com.example.shoesname.NewActivity.<init>(NewActivity.java:23)

 

NewActivity.java 23번째 줄에서 NullPointer예외가 발생했다고 되어 있네요

그 부분을 살펴보시면 되겠습니다

Answer 2

11-18 06:14:23.107: E/AndroidRuntime(1327): Caused by: java.lang.NullPointerException

 

NullPointerException은 값이 존재해야할 곳에 아무것도 없는 Null 값이 입력되어서 생기는 오류입니다.
