App breaks after returning from home

Question

I have app, when I press home button and wait some time, trying to return to app, I am getting force close and my app shows nonsense’s.

Only error I found:

java.lang.OutOfMemoryError: (Heap Size=98304KB, Allocated=90124KB)

How can I prevent this to happen?

Edit:

There is very useful speech about memory leaks finding:

What are you doing in your onResume Method to get that amount of memory usage? java.lang.OutOfMemoryError Do you have big pictures or Bitmaps in your View? — A.S., Oct 04 '13 at 13:37
In that activity i am using about 7 fragments. On resume method i check play services, edit prefs, fix few views. Does it posible that problem appears because i am using static list of Drawables for cache? and some ListViews data in static lists? — MartasSan, Oct 04 '13 at 13:50

also make sure that the images (if you are using any) are not above the required resolutions. As very large images or backgrounds can also cause an OOM exception.
