Question

I am trying to get Android’s MediaStore to write an image to the SD card with a specific file name. It does write the file, but does not use the title parameter passed with

MediaStore.Images.Media.insertImage(cr, source, title, description)

Here is my relevant code:

PictureCallback myPictureCallback_JPG = new PictureCallback(){

     public void onPictureTaken(byte[] arg0, Camera arg1) {
      Bitmap bitmapPicture = BitmapFactory.decodeByteArray(arg0, 0, arg0.length);

        int year = Calendar.getInstance().getTime().getYear();
        int month = Calendar.getInstance().getTime().getMonth();
        int day = Calendar.getInstance().getTime().getDay();

        int hour = Calendar.getInstance().getTime().getHours();
        int minute = Calendar.getInstance().getTime().getMinutes();
        int seconds = Calendar.getInstance().getTime().getSeconds();

        String imgName = "IMG_" + Integer.toString(year) + Integer.toString(month) +Integer.toString(day) + "_" + Integer.toString(hour) + Integer.toString(minute)
                          + Integer.toString(seconds) + ".jpg";         

        MediaStore.Images.Media.insertImage(getContentResolver(), bitmapPicture, imgName, imgName);    

        camera.startPreview();
        inPreview=true;
     }};

It successfully stores the picture, but the file name appears to be time since the Unix epoch (i.e. 13168297…16.jpg)

Answer 1

I didn’t get MediaStore to work, but I did use the File class and FileOutputStream to get the job done:

        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bitmapPicture.compress(Bitmap.CompressFormat.JPEG, 100, bytes);

        File imageDirectory = new File(Environment.getExternalStorageDirectory() + File.separator + "DropPic 64");

        imageDirectory.mkdirs();

        File f = new File(Environment.getExternalStorageDirectory()
                                + File.separator + "DropPic 64" + File.separator + currentPicture.fileName);
        try {
            f.createNewFile();
            FileOutputStream fo = new FileOutputStream(f);
                fo.write(arg0);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
