Fixing Fatal Exception: main process Errors

Question

I am a beginner to using Java and Android Studio, this code is part of a project from class for a point and click mole game. Clicking the mole a certain amount increases the level and after can be submitted as a high score. The game saves each players highscore as a generated button, the problem I'm having is the condition I have to sort the highscores by highest level reached. The LevelArray contains the the highest levels players have reached and I'm trying to get them in a condition so I can sort the generated buttons. If my idea does not work can someone offer another method for sorting these buttons? Below I included the global page I have wit enter code here h the page containing the loop, and included the errors I received when entering the page with the loop.

Answer 1

Looks like you have 2 arrays but treat them as they have equal number of elements.

Perhaps the level array has less children than the name array?
