Question

My application requires image file to be selected from SD card and the selected image should be converted or encoded to base64 binary format string.I am able to fetch image file from SD card and fetch its path and name, but unable to convert it to base64 binary format string.

Thanks,

Answer 1

To convert image into base64 string:

Bitmap bm = BitmapFactory.decodeFile("/path/to/image.jpg");
ByteArrayOutputStream baos = new ByteArrayOutputStream();  
bm.compress(Bitmap.CompressFormat.JPEG, 100, baos);   
byte[]  = baos.toByteArray(); 

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