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. At the last image, the next button will be replaced by "Continue" button which will lead the user to the game over screen
Problem: Every time, i reached the last picture and attempt to answer it or when the "continue" button appears, and I click it also causes the game to crash. "unfortunately, pic has stopped"
The error message is pointing to the line:
if (wordBANK.contains(result.get(0).toLowerCase()) && UnSpokenList.get(randomNum).contains(result.get(0).toLowerCase())) {
I don't see any problem with this line as it been working fine for the previous images until the very last image.

Any ideas? Thank You in advance!
It looks like you are removing an element from UnSpokenList in onActivityResult but not altering the value of randomNum prior to getting the final image.
Add the following logging above the line where the app crashes and you'll see the error:
Log.i("TAG", "The array size is : " + UnSpokenList.size());
Log.i("TAG", "Attempting to get random position: " + randomNum);
