Open "Clash of clans" on Android, go to settings, click Link Device, enter Google Plus, click Accept, click Login. Again go to the settings, click Link device, mark Old device, then Link to another device. The game generates kol, enter it on your iOS device
This can be done.
First, make sure you have completed the tutorial in the game on Android, then the "Settings" interface will be available to you.
In the "Settings" click the "Link device" button. You will need to log into your Google account, the game itself will offer to do this. Accept the license agreement to link your Clash of Clans data to your Google account.
Then go back to Settings and click the Link Device button. Then click the This Old Device button and then select Pair to Another Device.
A code will be generated that will need to be entered within 2 minutes on the iOS device. IMPORTANT: on iOS, your Town Hall must not reach level 4, otherwise you will have to delete the Village and create a new one.
To enter a code on iOS, open Settings, select "Pair device", then "This is a new device", after which a special field for the code will be available. You need to have time to enter it before the expiration of 2 minutes and click the checkmark or "Ok".
The game will ask you "Are you sure you want to delete the Village"? Agree - then the Village on iOS will be replaced by the Village on Android.
Done! Be careful: it is impossible to simultaneously launch the game under the same account on two devices at once, so the application will be exited on an Android device.
