I never used c++ for android and NDK before. When I use it for - say - image processing I want to be sure app will work on all devices with android 2.2 and higher.
When I write for iPhone, xcode compiles 2 binaries for arm7 and arm7s architectures and packs them into the same bundle.
Now I've written a sample NDK app which doesn't want to run on x86 android emulator while running well on my Nexus 7. I think it's obvious that should be the way to make it run both on arm and x86, but still can't find it. Does somebody know? Thanks!
