After that, in that time i installed whatsapp business in my android, but i have goten problem my whatsapp business can't be install used number i have using for fanpage pacebook and the integration in BotSailor.

Are there solution for my problem?

There can possibly be two reasons why you are facing this problem.
1. WhatsApp has a limit on the number of accounts that can be associated with a single phone number. If you've already created a WhatsApp Business account with that number, you might not be able to create another one. So you have to use another phone number.
2. If you've violated WhatsApp's terms of service or experienced issues with your account in the past, your ability to create new accounts might be restricted. So please check if you've received any notifications or warnings from WhatsApp.

ooo.. i see but thank's,
and how about do clone account?
my whatsapp business in botsailor clone to whatsapp business in my android, are there possibly do that?

Unfortunately, there's no direct way to clone a WhatsApp Business account from Botsailor to an Android device.
