how to save text to file in Android Studio?



I want to create file in which the first line will be constantly updated. actually I want to save this file to custom path, for example /storage/emulated/0/Download, but I don’t know how to do that, so now I have something like this:

public void save(){
    while(true) {
        try {
            String FILENAME = "my_file";
            String string = "" + System.currentTimeMillis();

            FileOutputStream fos = openFileOutput(FILENAME, MODE_PRIVATE);
        } catch (Exception e) {



and this code gives me two errors

  1. Cannot resolve method ‘openFileOutput’
  2. Cannot resolve symbol ‘MODE_PRIVATE’


 FileOutputStream fos = getApplicationContext().getContextResolver().openFileOutput(FILENAME);

Before using openFileOutpout() you have to use getContextResolver() and there is no Context.MODE_PRIVATE parameter in this function
