Question by MapuHoB · May 21, 2015 at 04:07 PM · devicefilter

Device Filter to ARM 7 only

I'm making totally small and simple game, very, very small. Yet when I build the apk it gets over 20mb. I did the research, everybody says just change the device filter to ARM 7. I did it, my apk size got reduced drastically but I still didn't understand the concept.

1) How many devices am I excluding when the device filter is ARM 7 only?

2) What is the main difference between x86 and ARM 7?

3) What are the cons of choosing only ARM 7?

4) Is it worth choosing only ARM 7, for saving 8mb?

5) Can I make sure that only devices with ARM 7 can only install the game from google play? Because if I can't and many people will try to download it, only to see that it's not working and they will most likely downvote.

ARM and x86 are both processor architectures. x86 belongs to Intel while ARM is used by different companies (like Qualcomm). The vast majority of Android devices use ARM processors, with x86 being the runner up. When you build for ARM only you lose some of your target audience which might use Intel android devices.

With that being said:

  1. I don't know but I would love to find out.

  2. They are different CPUs. For you as a developer, if you don't use Android's NDK, it doesn't matter. You can keep building your .apk for both and you'll be fine.

  3. None really, beside the smaller .apk size

  4. Probably not. All those Asus ZenPad and ZenFone devices might end up in consumer homes and they are also, I suspect, your target audience.

  5. Don't know. You can create an experimental app and check that for yourself if you can find someone with a x86 device.

About 1. Unity stats says that Top on 2016-03: AR$$anonymous$$: 98.7% Intel: 1.3% http://hwstats.unity3d.com/mobile/cpu.html

You are totally free to make two separate builds, one for AR$$anonymous$$ and one for x86 and submit them separately to Google Dev Console. Play will detect the device the user is using and give them the appropriate AP$$anonymous$$.

Heres a similar question. Link to '$$anonymous$$ultiple AP$$anonymous$$s' there-in.
