As I said.
You’re giving a list to the input however, you should give a string in it.
Use join block and join the text of all three textboxes then pass it to the input instead of adding them in list.
I have already done that but still there are so many problems, it’s creating extra blank list also If I try to create word from more than 8 letters it takes so much time and shows error. I want to create 15 or 20 words from the letters not more than that is it possible?
Most of the programs which generate anagrams put a limt for the number of angrams that can be generated
As far as i know the number of anagrams for 9 letters is 362880 items and apparently it is too much for the capacity of the android.
Maybe i have to put a limit in my extension.
