When I run my app it just opens a white screen and stays there, it slows my whole phone down until I'm forced to shut it down. Logcat says that the first error is "Perfoming stop of activity that is not resumed". I don't really have a onResume on my main file. Should I have a onResume or is there another way to fix this problem?
Here is the error I get when it runs:
