Bitmap size on disk issue in Android

Question

In my Application, i need to download the image from server and save it in SDcard. I am using Volley library to download the image from server. Issue in my Application is when i am downloading the image from server it is 30kb and after downloaded checking the size of that image in SDcard was 200kb.

This is my SavedSDcard() which is used to save the image in SDcard and returning the ImagePath.

public String SavedInSDCard(Bitmap bitmap_in, String id) {

    File dir = new File(ApplicationController.getInstance()
            .getExternalFilesDir("MyApplicationName") + "/Cache");
    // Create the storage directory if it does not exist
    if (!dir.exists()) {
        dir.mkdirs();
    }

    File file = new File(dir, id);
    try {
        FileOutputStream out = new FileOutputStream(file);
        bitmap_in.compress(Bitmap.CompressFormat.JPEG, 100, out);
        out.flush();
        out.close();
    } catch (Exception e) {
        e.printStackTrace();
    }

    String imgPath = dir + "/" + id;
    return imgPath;
}

I don't understand your code. Where is "bitmap_in" used and what is bitmap2? Why do you use compress? — daemmie, Jul 03 '15 at 05:35
@maveň Downloaded ImageSize is not same as image Size which is in Server — Ashok, Jul 03 '15 at 06:16

bitmap2.compress(Bitmap.CompressFormat.JPEG, 100, out);

Remove above line from the code.

First

bitmap2.compress(Bitmap.CompressFormat.JPEG, 100, out);

You can decrease the value of 100 for reducing the Image Size. put 70 or 80 instead of 100.

Second
