Actually, the bug is known by the author. I talked with him on Twitter. It should be fixed soon I hope.
I found a workaround:
- Buy and use the pro version 0.50.1 of tic
- Save your cart like this : save nameofyourcart.lua (it creates a text version of the cart)
- install DroidEdit application
You can now code with DroidEdit and just switch to TIC. It will automatically reload the cart. Just run it.
The carts are in Android/data/com.nexbox.tic/......
