i have an okcash windows7 desktop wallt and i want to open it with the coinomi software for android.
unfortunately i cant do this.
Coinomi want´s me to enter the secret sentence to unlock my wallet. if i do so it says "cant verify sentence. Word list size must be multiple of three words".
What am i doing wrong?
Well I would guess that your Coinomi passphrase isn't the right one.
What do you mean you want to open your desktop wallet with Coinomi? It doesn't work like that. You can't open whatever wallet with whatever app. Also the public key doesn't do much besides allowing you to receive coins. It's the private key that you need for backups.
