Question

I am trying to write a file in Android.

private void writeScoreToFile(BlastScore result)
    {
        try{
            FileWriter fstream = new FileWriter(CaptureActivity.BLAST_SCORES,true);
            BufferedWriter out = new BufferedWriter(fstream);
            out.write(Integer.toString(result.getBlastScore()));
            out.close();
        }catch (Exception e){
            System.err.println("Write Error: " + e.getMessage());
        }
    }

I get the error:

10-28 21:04:11.200: W/System.err(669): Write Error: /BlastScores.txt (Read-only file system)

How can I resolve this?

Answer 1

You’re trying to write to the root directory. You probably want to be writing to your app’s directory, not root.

To do that, use Context.openFileInput and Context.openFileOutput instead of new FileWriter.
