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

This code runs perfect in my project:

profile_image.buildDrawingCache();
Bitmap bmap = profile_image.getDrawingCache();
String encodedImageData = getEncoded64ImageStringFromBitmap(bmap);


public String getEncoded64ImageStringFromBitmap(Bitmap bitmap) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.JPEG, 70, stream);
    byte[] byteFormat = stream.toByteArray();

    // Get the Base64 string
    String imgString = Base64.encodeToString(byteFormat, Base64.NO_WRAP);

    return imgString;
}
