append to file android

Question

hey there, i need to append to my file but it is not working, it keeps overwriting the file, can anyone please tell me what is wrong:

  public void generate         


        

Answer 1

You can fix it by changing the line where you assign the BufferedWriter:

bW = new BufferedWriter(new FileWriter(gpxfile, true));

When you open a file using the FileWriter constructor that only takes in a File, it will overwrite what was previously in the file. Supplying the second parameter as true tells the FileWriter that you want to append to the end of it.
