Cannot build tutorial included in Ren'Py 7.1.0

[muffintosh]

Hi! I am new to Ren'Py. I have built sample games by using Ren'Py for android or desktop to test the functionality of building for those platforms. It works on my laptop, except one, the tutorial included. I could not built it. I want to build it and run it on my android mobile phone to save some tutorial reading time on the commute. It shows two error screens one after another, they are in the attachment. What is the reason? How can we solve that?
I am on MacOS 10.13.6, and Ren'Py 7.1.0.

The Tutorial isn't currently Android compatible so even if you find whatever is causing this error, it still won't work properly, unfortunately.
It is because of how the tutorial displays the code on screen.

You could modify the tutorial to not use the keywords file - which is the reason it isn't Android compatible, but it would take considerable work.

Thank you for prompt response. Actually it has managed to build after Ren'Py 7.1.1 update. But it still does not launch on Android phone, it does not pass through the renpy on android splash screen, it crashes.
Can you explain more why the way renpy shows code on screen is an incompatibility issue? What causes this?

The examples system is not supported on Android, among other things. I have no plans to support the tutorial on non-pc platforms.
