Ways to read and write private files in Android programming _android

This example describes the way to read and write private files in Android programming. Share to everyone for your reference, specific as follows:

A private file is a file that the program itself can read, and other programs do not have permission to access, which is saved in the Data.app. Package. File directory.

The method of writing a file is simpler:

private void WriteFile (string filename, string info) {
 try {
  FileOutputStream fout = openfileoutput (filename, MOD E_private);
  byte[] bytes = Info.getbytes ();
  Fout.write (bytes);
  Fout.close ();
 } catch (Exception err) {
 }
}

This completes the writing of the private file, using the Openfileoutput file when writing a private file.

The private file is written above, and the private file is read below:

private string ReadFile (string filename) {
 try {
  fileinputstream fin = openfileinput (fileName);
  int length = fin.available ()//Get file length
  byte[] bytes = new Byte[length];
  Fin.read (bytes);
  Return encodingutils.getstring (bytes, ENCODING);
 } catch (Exception err) {return
  "";
 }
}

Use "Openfileinput" to read private files!
