I was having the same issue. after a few days of messing with the code I noticed this method was returning empty bytes[]

`
public byte[] getData() throws IOException
{
int length = (int)getDataLength();
byte[] bytes = new byte[length];

    int offset = 0;
    int bytesRead = 0;

    InputStream in = openInputStream();

    while (offset < bytes.length) 
    {                 
        bytesRead = in.read(bytes, offset, bytes.length - offset);

        if (bytesRead < 0)
        {
            break;
        }

        offset += bytesRead;
    }

    in.close();
    
    if (offset < bytes.length)
    {
        throw new IOException("Failed to read complete data of MMS part");
    }
    
    return bytes;
}

`

I updated the method to this and now it works:

` public byte[] getData() throws IOException
{
InputStream inputStream = openInputStream();
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
int nRead;
byte[] data = new byte[RAW_DATA_BLOCK_SIZE];

    while ((nRead = inputStream.read(data, 0, data.length)) != -1) {
      buffer.write(data, 0, nRead);
    }
    buffer.flush();
    return buffer.toByteArray();
}

`

I have attached a modified version of the .apk containing this change;
