How can I convert an image into a Base64 string?

Question

What is the code to transform an image (maximum of 200 KB) into a Base64 String?

I need to know how to do it with Android, because I have to add the functionali

Answer 1

I make a static function. Its more efficient i think.

public static String file2Base64(String filePath) {
        FileInputStream fis = null;
        String base64String = "";
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        try {
            fis = new FileInputStream(filePath);
            byte[] buffer = new byte[1024 * 100];
            int count = 0;
            while ((count = fis.read(buffer)) != -1) {
                bos.write(buffer, 0, count);
            }
            fis.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        base64String = Base64.encodeToString(bos.toByteArray(), Base64.DEFAULT);
        return base64String;

    }

Simple and easier!
