Append to file outside external storage default folder in Android

I want to build a TXT file and add new lines to it every time.
I don't want it to be in the app data folder in external storage (default folder used in openFileOutput()) since it's erased as the app uninstalled (This is a log meant for these issues). How can it be done ?

Use FileWriter. The constructor's second argument defines whether an existing file should be opened and appended.

FileWriter writer;
try {
    writer = new FileWriter(yourFilePathHere, true);
    writer.write("Hello World");
    writer.flush();
    writer.close();
} catch (IOException e) {
    //Error handling
}

yourFilePathHere might be new File(getExternalStorageDirectory(), "log.txt").getAbsolutePath();
