Brief Description: The application will display random images to the user based off the words from the word bank file and the user will have to identify the name of the image, (single word). The user can either "pass" by clicking the pass button or identify the image and then the "next" button will pop up directing them to the next image.
Problem: The application keep crashing right before the new next button appears with different images when I attempt to press the next button.
I think that it has something to do with the random number generator or an issue with the if statements i placed.
I am getting no error message. I am not sure what is causing the issue. When I do run the apk file, when it crash it says "unfortunately, pic has stopped" "pic" is the app name.
The next button is clicked and changes to the next image which is randomizes by the code:
randomNum = (random.nextInt(UnSpokenList.size()) + 1);
the first element, contains "Word Bank:" which is not an image, it just the name of the list of word, so I did random.nextInt(maxsize)+1 , which I assume avoids 0, the first element, but when it comes down to the arraylist have the size of 2
(it crashes right before this part, but it does crashes when this next button is click as well.) In the onActivityResult function when it size 2 or less then 2, it will stop showing this next button and show a different next button which call the function onlastPair, which produce images based off the last element of the arraylist.
Main Code: I took some code off functions that aren't related to the issue hopefully it will be easier to find the main problem.
