Question

How to encode and decode any image from base64 format.

I donno anything about base64, just now I came to know that it saves image in String format. Please explain ab

Answer 1

Base64 allows you to represent binary data in ASCII format, You can use it for send/receive images to an endpoint

To encode/decode check this two methods:

public static String getBase64(Bitmap bitmap)
{
    try{
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();  
        bitmap.compress(Bitmap.CompressFormat.JPEG, 90, byteArrayOutputStream);
        byte[] byteArray = byteArrayOutputStream.toByteArray();

        return Base64.encodeToString(byteArray, Base64.NO_WRAP);
    }
    catch(Exception e)
    {
        return null;
    }
}

public static Bitmap getBitmap(String base64){
    byte[] decodedString = Base64.decode(base64, Base64.NO_WRAP);
    return BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
}
