I use latest 0.78 jar library. I need encryption on my realm db, but i get error after app closed and released from memory.

This error can only occur when you open an instance of a Realm file (the getInstance() call). Can you provide a little background information?

• do you use encryption? and do you use the same encryption key?
• did you delete your Realm file (the deleteRealmFile() method) after calling getInstance()?
• do you try to open a non-default Realm file in a non-existing folder?

[eugeneek]

I use encryption. I use code below while get realm instance:
byte[] key = new byte[64];
new SecureRandom().nextBytes(key);
realm = Realm.getInstance(this, "name", key);

No, i don't delete realm file after calling getInstance(). This exception occurs exactly on getInstance() line.

I try to open non-default file but don't try non-default folder.

It looks like you're trying to access the Realm file with a different key every time since you don't provide a seed to SecureRandom. That will of course provoke the error you reported.

Thank you, it was my bad. But i do exactly what i saw in docs. Please update docs, because there still
Using Encryption requires building Realm from source. and used 32 length byte array for key.
