Hi,

      I would like to share a cache file across activities, which are
running in different processes but in a same application.

      The operations on the file are:
      Read: context.openFileInput->read fileInputStream->close
fileInputStream
      Delete: context.deleteFile
      Write:context.openFileOuput->Write to fileOutputStream  ->close
fileOutputStream

      So, is there any way to make it thread safe (probably not
"thread safe", should we call it "activities safe" or "process
safe" ?:-) )

Thanks a lot.
