Error message running android.py and androidkindlekey.py

[ableeker]

On my machine android.py (and androidkindlekey.py) abort with an error message:

File “F:\eBooks\Android\android.py”, line 137, in get_serials2
tokens = [x[0].encode(‘utf8′) for x in cursor.fetchall()]
AttributeError: ‘NoneType’ object has no attribute ‘encode’

I think the encode part will only work as long as none of the results are NULL: if a result is NULL, you can’t encode it to UTF-8. On my machine at least, some results unfortunately are NULL. So what you’d like to do is only encode the particular result if it isn’t NULL. I’ve tried to do that by rewriting the line like so:

if not tokens:
[x[0].encode(‘utf-8′) for x in tokens]

This runs without an error message, but because I don’t know Python that well, I’m not entirely sure it does what I want. This produces different keys, but they don’t work, as in they don’t decrypt the ebook. This may well mean that statement is wrong, which wouldn’t surprise me at all.

However, at first I got rid of the error message by just 'ignoring' the token. I ignored the tokens by replacing the line with just 'tokens = ['']'. This produced a key which weirdly enough DOES work.

Thanks for reporting this bug.

Actually, what works is:

dsns = cursor.fetchall()

and

tokens = cursor.fetchall()

If you ignore tokens, you get just half a key. I was lucky, because on one of my devices this was the entire key, but on one of my other devices, I needed both halves, so tokens = [''] doesn't work. Is it really necessary to encode the keys in UTF-8 anyway? After all there's no difference if you only use 7-bits ASCII.

Thanks for the extra info. I’m putting android to one side briefly while I concentrate on getting the B&N URL fix done. (I tried doing both at once which was a mistake, just from a keeping things straight in my mind point of view.)

I’m currently working on a 6.2.2 without the android stuff, and once that’s done I’ll move on to getting a 6.3.1 release with the Android code in it. If I have problems at that point I might get back to you.

Thanks again for the interest,

Harper.
