@Louisbreadfish Once you have a game going, and a cabin built for the other player, go into the menu -> options tab and scroll down to the multiplayer section. Press the "start local co-op" button
The mobile 1.5 update has been submitted for iOS and Android, and will start rolling out to users over the next few days. The update should already be available to some on Android.
Some things to note:
On Android you will be asked to do a 1 time save file transfer. This was necessary because of new operating system rules concerning file access.
We're committed to fixing any bugs in this mobile update and will be following up with patches as needed. Also I plan on bringing back Simplified Chinese language with a patch soon.
@Hubert69554604 are you sure it's not working? The screenshots are saved in a new location now... check Android/data, find the stardew valley folder and check in there
1.5 mobile should be out for iOS now. We're aware of some bugs and issues with both versions and we're working to fix them as quickly as possible. Thank you
@britishchick21 if you "check" the children twice it currently crashes the game if you have nothing selected in the toolbar. Either select something in the toolbar, or only check on the children once each day. This will be fixed soon
