lAndroid NDK, Revision 10(July
2014)

Important changes:

• Added 3 new ABIs, all 64-bit: arm64-v8a, x86_64, mips64. Note that:
  • GCC 4.9 is the default compiler for 64-bit ABIs. Clang is currently version 3.4.NDK_TOOLCHAIN_VERSION=clang may not work for arm64-v8a and mips64.
  • Android-L is the first level with 64-bit support. Note that this APIlevel is a temporary one, and only for L-preview. An actual API level number will replace it atL-release.
  • This release includes now includes all32 and all64settings forAPP_ABI.
    • APP_ABI=all32 is equivalent toAPP_ABI=armeabi,armeabi-v7a,x86,mips.
    • APP_ABI=all64 is equivalent toAPP_ABI=arm64-v8a,x86_64,mips64.
    • APP_ABI=all selects all ABIs.

虽然上面说的APP_ABI=ALL32 但其实指的是32bit 的NDK 包下午的编译选项，并不是说64bit NDK package 可以编译出32bit 的armeabi lib
