android 6 - open failed: ENOENT (No such file or directory) -

when creating new file, getting above error. code works in android 4.4 version . testing on 6.0.1 device , getting error. have write permission in manifest file, tried mkdirs() before creating file, still same issue. here code snippet :

file newfile = new file(localfilepath);         try {             string abc = null;             abc = environment.getexternalstoragestate();             if(!newfile.exists()) {                 newfile.mkdirs();                 newfile.createnewfile();             }         } catch (ioexception e1) {             e1.printstacktrace();             return false;         } 

the externalstoragstate comes 'mounted'. storage location /storage/emulated/0/testlocation/filename..

you have give run time permission 6.0
