이게 소스코드인데요 이렇게 코딩해서 이미지를 넘기면서 이미지의 이름과 같은 txt파일로 메모를 남길려고 하는데요

txt파일 이름을 이미지와 같은 이름으로 하고 싶은데 자꾸 앱이 중지되네요 실행하기도 전에...

배열인덱스번호로 txt파일을 생성하면 가능한데 이름대로 할려고 하니까 안되네요

substring을 사용해도 똑같이 앱이 중지되네요

혹시 에러 코드좀 보여주실수 있나요...

콘솔창에 에러코드는 보이지 않고 로그같은 경우에는

Warning: The environment variable HOME is not set. The following directory will be used to store the Git
user global configuration and to define the default location to store repositories: 'C:\Users\Nope'. If this is
not correct please set the HOME environment variable and restart Eclipse. Otherwise Git for Windows and
EGit might behave differently since they see different configuration options.

이거랑
 
Warning: EGit couldn't detect the installation path "gitPrefix" of native Git. Hence EGit can't respect system level
Git settings which might be configured in ${gitPrefix}/etc/gitconfig under the native Git installation directory.
The most important of these settings is core.autocrlf. Git for Windows by default sets this parameter to true in
this system level configuration. The Git installation location can be configured on the
Team > Git > Configuration preference page's 'System Settings' tab.

이게 있네요 전 아직 공부가 부족해서 로그까지는 잘 모르거든요 ㅠㅠ
