How to convert image into byte array and byte array to base64 String in android?

Question

Can someone tell me the code to convert image into byte array and that byte array into base64 string. i write the below code not getting proper result .

  String filepath = "/sdcard/Image/ic_launcher.jpg";
   File imagefile = new File(filepath);
        FileInputStream fis = null;
        try {
            fis = new FileInputStream(imagefile);
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        Bitmap bm = BitmapFactory.decodeStream(fis);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();  
        bm.compress(Bitmap.CompressFormat.JPEG, 100 , baos);    
        byte[] b = baos.toByteArray(); 

        String encodedImage = Base64.encodeToString(b, Base64.DEFAULT);

result im getting is

and at end of this byte array im getting this 3 dots and array is not completed ,so how can i get correct byte array 

base64 string is

/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEB

Answer 1

Try this:

// convert from bitmap to byte array
public byte[] getBytesFromBitmap(Bitmap bitmap) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.JPEG, 70, stream);
    return stream.toByteArray();
}

// get the base 64 string
String imgString = Base64.encodeToString(getBytesFromBitmap(someImg), 
                       Base64.NO_WRAP);
