Android Image to Base64 String Issue

Question

I want to pick an image from galery and convert it to base64 string for insert to database. But this string has empty characters and very very long. When I did it same process in asp.net, decoded string wasn't long that much and it hasn't empty characters. I'm getting error because of returned very long string. How can I do this ?

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

imageStr = Base64.encodeToString(b, Base64.DEFAULT);

imageStr returned like this:

/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEB

Answer 1

Use Base64.NO_WRAP flag to strip line breaks

Use 90 quality when compressing will greatly reduce the output size. the length of the output will be 4/3 times of the length of the byte array
