I'm new to android and am making an app which features many activities and a user prefs get edited during almost every one, and it seems that it randomly starts crashing 6 or 7 activities in, and opening up a different activity from a couple of pages ago, but only sometimes. I do everything exactly the same each time and I don't know what causes it to crash. Usually it will crash back to a different intent and let me continue from there. Here is the logcat after a crash:

  • While those are lines from LogCat, they do not pertain to your problem. You are looking for a Java stack trace: https://stackoverflow.com/questions/23353173/unfortunately-myapp-has-stopped-how-can-i-solve-this – CommonsWare Oct 31 '15 at 20:06
  • Thanks. Having out of memory error, oh no. How have I seen apps that must use so much more memory then? – user3169700 Oct 31 '15 at 20:17
  • They're doing a better job of memory management, which is a complex topic in Android. On [my videos page](https://commonsware.com/videos) there is a conference presentation that I delivered last year on memory management that may be of use to you. – CommonsWare Oct 31 '15 at 20:21
