Android: problems creating a file

Question

I'm writing an Android application in which I want to create text files in a particular folder and afterwards I want to read the files from my device. I'm doing this way:

 File sd = Environment.getExternalStorageDirectory(); File f; FileWriter fw = null; String path = sd.getAbsolutePath() + "/Samples/"; f = new File(path+File.separator+"filename.txt"); if (!f.exists()) { f.mkdirs();//Creates the directory named by this file, creating missing parent directories if necessary try { f.createNewFile(); //fw = new FileWriter(f, true); } catch (IOException e) { Log.e("ERROR","Exception while creating file:"+e.toString()); }

The problem is that in this way I create another folder instead of a text file. What can I do? Thanks

Instead of:

f.mkdirs();

do:

path.mkdirs();

Hi, thanks for your answer and sorry if I don't have answered before. I'm afraid I can't do path.mkdirs() because path is a string, while mkdirs() is a method of File class

I found the solution and I want to share it with you:

 File sd = Environment.getExternalStorageDirectory(); File folder; String path = sd.getAbsolutePath() ; folder = new File(path, dirName); if (!folder.exists()){ folder.mkdirs();} try{ File file = new File(folder, fileName+".txt"); file.createNewFile(); } catch (IOException e) { Log.e("ERROR", "Exception while creating file:" + e.toString()); }

I hope this could help other people having the same problem. Good luck
