reading-writing

//I have this two methods for read and write in SD memory
//THe problems is when i try to retrieve the image the quality is very low. What can i do?

//WRITE
public String saveToSD(Bitmap outputImage){

        //THis create a directory
        String name_millis = Long.toString(System.currentTimeMillis());
        String directory = Environment.getExternalStorageDirectory() + "/.sales_tracker/";
        File storagePath = new File(directory);
        storagePath.mkdirs();

        File myImage = new File(storagePath, name_millis + ".jpg");

        try {
            FileOutputStream out = new FileOutputStream(myImage);
            outputImage.compress(Bitmap.CompressFormat.JPEG, 100, out);
            out.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return "/.sales_tracker/" + name_millis + ".jpg";
    }
    
    //READ
    public Bitmap readImageFromExternal(String path){
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inPreferredConfig = Bitmap.Config.ARGB_8888;
        Bitmap bitmap = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory().getAbsolutePath() + path, options);
        Bitmap return_bitmap = Bitmap.createScaledBitmap(bitmap, 100, 100, true);
        return return_bitmap;
    }
    
    //HERE IS THE LOGIC OF SEND IMAGE
    Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
                Uri mImage = Uri.fromFile(new File(path));
                File file = new File(path);


                //HERE THE LOG CAT SAY EXIST!!!!
                if(file.exists()){
                    Log.v("EXIST", "EXIST");
                }else{
                    Log.v("NOOOO EXIST", "EXIST");
                }

                String [] to = {"vatslavds@gmail.com"};
                emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, to);
                emailIntent.putExtra(Intent.EXTRA_SUBJECT, "");
                emailIntent.putExtra(Intent.EXTRA_TEXT, "Nombre: " + sentEvidence.get(0) + " Comentario: " + sentEvidence.get(1)
                        + " Tipo: " + sentEvidence.get(2) + " Marca: " + sentEvidence.get(3));
                emailIntent.setType("image/jpeg");
                emailIntent.putExtra(Intent.EXTRA_STREAM, mImage);
                startActivity(emailIntent);

//BUT AT THE END NONE IMAGE WAS ATTACHED WHY?!?!?
