// Put the image file path into this method
public static String getFileToByte(String filePath){
    Bitmap bmp = null;
    ByteArrayOutputStream bos = null;
    byte[] bt = null;
    String encodeString = null;
    try{
        bmp = BitmapFactory.decodeFile(filePath);
        bos = new ByteArrayOutputStream();
        bmp.compress(Bitmap.CompressFormat.JPEG, 100, bos);
        bt = bos.toByteArray();
        encodeString = Base64.encodeToString(bt, Base64.DEFAULT);
    }
    catch (Exception e){
      e.printStackTrace();
    }
    return encodeString;
}
