Build HelloWorld on android x86 platform¶

NDK supports x86 platform from ndk-r6, but it has a bug. You can not build x86 and armxxx into one apk.
For example, you can not write like this in Application.mk:

APP_ABI := armeabi x86

ndk-r6b fixes the bug, so use it.

Build HelloWorld¶

1. Support x86 only
Change the APP_ABI in HelloWorld/android/jni/Application.mk

 APP_ABI := x86 

2. Support x86 and armxxx
Change the APP_ABI in HelloWorld/android/jni/Application.mk

 APP_ABI := armeabi armeabi-v7a x86 

What is the APP_ABI mean¶

When you define APP_ABI in Application.mk, you tell ndk how many architectures can the apk support.
For example, APP_ABI is armeabi and x86, then the apk can be installed on the phones which architecture
is arm or x86.
