How to resize/compress a camera image or gallery image in android before upload to server?

Question

I have to upload image which may be choose from gallery or take by camera. I have done this successfully. But problem is , some time image size is 1MB. So it takes more time to upload to server. I need to resize this image before upload. How to do this?

 public void onActivityResult(int requestCode, int resultCode, Intent data)
{
    AlertDialog alertDialog1;

    if( requestCode == REQUEST_IMAGE && resultCode == Activity.RESULT_OK ){
        try {
            FileInputStream in = new FileInputStream(destination);
            BitmapFactory.Options options = new BitmapFactory.Options();
            options.inSampleSize = 10;
            imagePath = destination.getAbsolutePath();
            Bitmap bmp = BitmapFactory.decodeStream(in, null, options);
            //img = (ImageView) findViewById(R.id.imageView1);
            int nh = (int) ( bmp.getHeight() * (512.0 / bmp.getWidth()) );
            Bitmap scaled = Bitmap.createScaledBitmap(bmp, 512, nh, true);
            img.setImageBitmap(scaled);
        } catch (Exception e) {
            // AlertDialog alertDialog1;
            alertDialog1 = new AlertDialog.Builder(getActivity()).create();
            alertDialog1.setTitle("Message");
            alertDialog1.setMessage("bala \t "+e.toString());
            alertDialog1.show();
        }

    }else if (requestCode == 1) {
        try {
            Uri selectedImageUri = data.getData();
            imagePath =  getPath(selectedImageUri);
            destination = new File(imagePath);
            FileInputStream in = new FileInputStream(destination);
            BitmapFactory.Options options = new BitmapFactory.Options();
            options.inSampleSize = 10;
            imagePath = destination.getAbsolutePath();
            Bitmap bmp = BitmapFactory.decodeStream(in, null, options);
            //int nh = (int) ( bmp.getHeight() * (512.0 / bmp.getWidth()) );
           // Bitmap scaled = Bitmap.createScaledBitmap(bmp, 512, nh, true);
            img.setImageBitmap(bmp);

            //img.setImageBitmap(bmp);
        } catch (Exception e) {
            // AlertDialog alertDialog1;
            alertDialog1 = new AlertDialog.Builder(getActivity()).create();
            alertDialog1.setTitle("Message");
            alertDialog1.setMessage("sang\t"+e.toString());
            alertDialog1.show();
        }
    }
    else{

    }
}

Now, how to resize the image?

Answer 1

1. To resize image you can use the following function

   Bitmap yourBitmap; Bitmap resized = Bitmap.createScaledBitmap(yourBitmap, newWidth, newHeight, true);

2. To compress the image

   Bitmap bmp = BitmapFactory.decodeFile(miFoto) ByteArrayOutputStream bos = new ByteArrayOutputStream(); bmp.compress(CompressFormat.JPEG, 70, bos); InputStream in = new ByteArrayInputStream(bos.toByteArray()); ContentBody foto = new InputStreamBody(in, "image/jpeg", "filename");
