Application starts with 86% memory usage(HeapSize)

I'm developing application for Android(Xamarin). At current moment is like prototype(inside nothing heavy).
I added app7compat support library and also implemented toolbar with navigation Drawer Layout.
I make some test on real device(Samsung Galaxy S4 Active) and it's an like glitch/bug,because when application started,android device monitor showing this :
enter image description here

How that is possible? My activity contains:

  1. Toolbar(with Drawer layout)
  2. Some different controls,like imageView and imageButtons

As i said,that comes from start(i mean that this 86% used memory allocated with strange items,because there is no computing logic).
Why this happens? Thanks!

Solution

  • As guys explained for me,that is ok,because from start application eats 86% of allocated memory(after that if needed, will grow up).

    Anothers tip was,to put flag largeHeap and via RunTime(),to see how much memory can be allocated: 

    Runtime rt = Runtime.getRuntime();
long maxMemory = rt.maxMemory();
Log.v("onCreate", "maxMemory:" + Long.toString(maxMemory/1024/1024));

    and my result(Samsung Galaxy S4 Active) was :

    512MB

    Hope that helps!
