Thanks to @Nick Campion and Sanselan.

Working code:

ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 100, bos); //Bitmap object is your image
byte[] data = bos.toByteArray();

TiffOutputSet outputSet = null;

IImageMetadata metadata = Sanselan.getMetadata(new File(filepath)); // filepath is the path to your image file stored in SD card (which contains exif info)
JpegImageMetadata jpegMetadata = (JpegImageMetadata) metadata;
if (null != jpegMetadata)
{
    TiffImageMetadata exif = jpegMetadata.getExif();
    if (null != exif)
    {
        outputSet = exif.getOutputSet();
    }
}
if (null != outputSet)
{
    bos.flush();
    bos.close();
    bos = new ByteArrayOutputStream();
    ExifRewriter ER = new ExifRewriter();
    ER.updateExifMetadataLossless(data, bos, outputSet);
    data = bos.toByteArray(); //Update you Byte array, Now it contains exif information!
