Unity player android memory usage

Unity Engine

I was wondering if someone might be able to answer some questions for me about the memory usage of unity produced apks.

  1. how much memory does the unity player itself use? provided I was simply playing an empty scene with a camera in it?

  2. I realize this is a little open ended but could anyone give me a solid understanding of how much memory I could expect a well optimized multi scene apk to use up?

  3. Can anyone give me some tips to minimizing memory usage on android?

erica, actually I have some stats (we tested in in Unity, compared to Unity iPhone 3, etc), but this may be outdated, as I had tested it prior to a ton of optimizations we did after that testing.

Why don’t you just create a blank scene and write down the stats yourself?

I was doing that using the profiler on my PC but is there a way to view that information while it’s actually on the android device? I was originally having a hard time getting an accurate representation of this information. I’ve since found this nifty little android app that acts as a task manager and will show both cpu and memory usage while your app is running, so i suppose that shouldn’t be an issue anymore.

When you were optimizing for android, what kinds of things were you doing? with what kind of results?

thanks
