Question

i am new developer in android.i would like to write some content to a file i have used a method to write into a file as follows

 public void writeFile(String path,String text){
    try{
    Writer output = null;
    File file = new File(path);
      output = new BufferedWriter(new FileWriter(file));
      output.write(text);
      output.close();
      System.out.println("Your file has been written");  
    }
    catch (Exception e) {
        e.printStackTrace();
    }

here i am passing path of a file and text to write.if i use in this way i can write the data but the previous data is losing.

how can i append or insert the latest text into a file without losing previous text?

Thanks in advance

Answer 1

Try this. Change this line …

output = new BufferedWriter(new FileWriter(file));

to

output = new BufferedWriter(new FileWriter(file, true));

The true indicates that you want to append not overwrite
