Paul, You cannot write to the top level 'cache' directory. You must write to the 'cache' directory in you application's package structure. I'm not using C so I can't give you an example there, but from java you can use your application's context to get the cache dir and use an io stream to write to it.
The file structure looks like this /data/data/your-package-name/cache --------------------------------------- Creator of My College Life http://mycollegelife.org On Apr 22, 2:20 am, paul2000 <hubao...@gmail.com> wrote: > any idea about this issue? thanks! > > On Apr 21, 11:49 am, paul2000 <hubao...@gmail.com> wrote: > > > > > Hi, > > > I created an android application.
