Save a file to the SD-card

.txt file need save in SD-card.

Save("n" + String.valueOf(key) + ".txt");

 private void Save(String FileName){
         File fileName = null;
         String sdState = android.os.Environment.getExternalStorageState();

         if (sdState.equals(android.os.Environment.MEDIA_MOUNTED)) {
             File sdDir = android.os.Environment.getExternalStorageDirectory();
             fileName = new File(sdDir, "FlyNote/"+FileName);
             } else {
                 fileName = context.getCacheDir();
             }
         if (!fileName.exists())
             fileName.mkdirs();
         try {
             FileWriter f = new FileWriter(fileName);
             f.write(editText2.getText().toString());
             f.flush();
             f.close();
         } catch (Exception e) {

         }
     }

But in the SD-card file saves as a folder. Folder "n5.txt" and other...

Most of the methods given here is good... You could also use this following code:

    public static void addToFile(String file,String message){

    try {
        FileOutputStream fos = new FileOutputStream(file,true);
        fos.write(("\n"+message).getBytes());
        fos.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

Here "File" is a string which contains the path to your file eg: File = "/sdcard/parentPath/FileName.txt" and "message" is for obvious the message that you want to enter into the file. (considering the file contains txt contents)

When you test for exists, you are searching if Flynote/Filename exists or not and if it doesnt exist you create one using mkdirs.

fileName.mkdirs() makes a directory with the name of that file. Hence you find the error. Your mkdirs should only be for Flynote and not Flynote/+FileName

Try this,

If you are aiming for a file, why r u using "mkdir" that makes a directory not a file.

This code is to create a file:

File f = new File("/sdcard/n5.txt");
FileWriter fw = new FileWriter(f);
BufferedWriter bw = new BufferdWriter(fw);
bw.write("Hello");

To check if the Folder exist...

File f = new File("/sdcard/myfolder");
if (f.exists()){

   // do what u want

   }
else{
       // doesnt exists
      }

use

File  dir= new File(sdDir.getAbsolutePath(), "FlyNote");
dir.mkdirs(); //CREATE DIR HERE
File  file = new File(dir, FileName);//CREATE FILE HERE

instead of

fileName = new File(sdDir, "FlyNote/"+FileName);
