Files not getting deleted in android -

in app, want delete 1 sqlite file , 1 txt file, doesn't work time.

i have given read/writes permissions in android manifest file.

is problem specific android version or there other way delete file in java.?

i using below code.

if(file.exists()){     file.delete()  } 

any idea?

maybe file still in use , cannot deleted. can use fileobserver check when file accessed. see http://developer.android.com/reference/android/os/fileobserver.html
