Can't save string when the value is empty

[Mingyueyixi]

hi,
When i save data with a empty string, It will throw Exception.

The code is:

EncryptedSharedPreferences.getInstance().setString("abc", "");

The Exception is:

Hi, can u provide MRE?

[Mingyueyixi]

Last week my project used a temporary solution where the empty string was saved with the key removed instead of stored.

Maybe that's probably not a good idea, and the other way is not encrypty the empty string,
but I'm in the country this weekend, and I can't verify it.

Sorry about that

Great, send me the MRE when it is possible. Good luck. I will close the issue if you can send me the MRE; I can reopen the issue.
