How to save files with incremented name

Question

outputFile = Environment.getExternalStorageDirectory()+ "/Myfolder/"+"/Recording.mp3";

I have been buiding this application for recording audio, and I wanted to have my recordings an unique name with an increment eg. Recording 01.mp3, Recording 02.mp3 etc. Any help would be appreciated.

You can store the number in SharedPreferences and add that to the filename, here an example of SharedPreferences

One way is to use SharedPreferences to store the increment number: First declare SharedPreferences as below:

SharedPreferences prefs = getActivty().getSharedPreferences("fileNumber",MODE.PRIVATE);

Then in your code you can:

int i = prefs.getInt('Number',1); 
outputFile = Environment.getExternalStorageDirectory()+ "/Myfolder/"+"/Recording" + Integer.toString(i) +".mp3";
i++;

And then save the incremented Number:

 SharedPreferences.Editor editor = prefs.edit();
    editor.putInt("Number",i);
    editor.apply();

I used it but then, it was overwriting files with only only one name. The iteration did'nt work. So kindly can you tell where should I put the i++ part? – Kunal Yadav Aug 12 '16 at 19:36
