두가지 에러 코드 해결방법좀 알려주세요..고수분들..

Question

DB와 연동하여 회원가입하는 앱 만들고 있는 중인데.. 회원가입 창으로 넘어갈때.. 저런에러들이 뜹니다..ㅠ

도와주세요...

첫번째 에러 handleWindowVisibility: no activity for token android.os.BinderProxy@e32d4c8

두번째 에러 JVMTI error: 15(JVMTI_ERROR_THREAD_NOT_ALIVE)  

이런 에러가 뜨는데 코드 부분 원하시면 댓글로 달아드리겠습니다.ㅠㅠㅠ

전반적으로 어떤 에러인지 구글링해도 잘 안나와서요...

Answer 1

회원을 확인하기 위해 서버에 데이터 전송을 thread로 하시는것 같은데 작업종료전에 다른 activity로 이동하여 이전 activity에서 수행하던작업에서 오류가 나온겁니다. thread를 종료후 이동해 보세요 . 만약 아니시라면 관련소스를 올려주시는것이 좋을듯 합니다.

질문에 보면  "회원가입 창으로 넘어갈때.. 저런에러들이 뜹니다" 라고하셨는데 앱실행후 registerBtn 만 클릭하신경우인가요 아니면 다른 다른 동작이 있는건가요.

이 코드부분이 메인부분인데 여기서 회원가입 버튼 누를시 저런 에러가 발생합니다. 위쪽에는 회원가입창의 액티비티구요..

activity 에서 선언한 stringBuffer  asynctask 에서 new를 하는것이 맞는지 확인햅보세요 .그리고 소스를 잘못 올려주신 것 아닌가 싶습니다. 회원가입을 하는게 아니라. 관리자회원 화면으로 넘어가는 것으로 보입니다. 그리고 onPostExecute 에서 값을 넣지도 않은 stringBuffer 를  넘기는 이슈가 좀 이상하고 확인해 보셔야할듯합니다.

아아 죄송합니다 잘못보내드렸습니다
처음에 댓글드린것이 로그인할때 화면에서의 액티비티이며
이번 답글이 회원가입 창에대한 액티비티입니다.
로그인화면에서 회원가입 버튼을 누르면
E/eglCodecCommon: glUtilsParamSize: unknow param 0x000082da
W/ActivityThread: handleWindowVisibility: no activity for token android.os.BinderProxy@166892c
라는 에러가 표시되고있습니다.
