App crash only in debug mode

Question

I am new to programming, and are trying to make an android app. The last few days I have really had trouble using the debugger. The app work just fine in normal run mode. The app are connected to firebase, and all data is saved there. If i try to log in as a student in debug mode the app crash rights away. If i log in as a professor i get to the mainpage, but if i click the next button i'll be thrown back to the login page, and it changes to run mode. I have really none idea what the problem is, but there is something about the debugger and firebase?

I dont know where i shall start to look in the error message i get, so i just post everything and hope someone knows this problem or could tell me where in the errorcode i shall look for the solution. Thanks! I post some of the error here:

the app starts with a log in, then you get to the mainpage, here you can push the subject button and go to the SubjectListAcitivty (and the app crash). On the subject¨List page it reads from the database which subjects the professor has added, and shows them in a listview. You can also add new subjects to the list (and save them in the database). This works fine in regular run mode, but not i debug mode. I am working on a new activity when you click on the subjects, but are not able to debug it because i can't even go to the SucjectListActivity. — Nina, Mar 26 '17 at 11:58

Take a look at this answer: Android app crashes when launched in debug mode. Try to remove all the breakpoints from nested functions. In Menu go to Run -> View Breakpoints and remove the unnecessary breakpoints.
