Android NDK更新版本的（OSX）路徑在哪裏？

Question

Android NDK更新版本的路徑在哪裏？我在Mac OSX 10.11.5（El Capitan）

我使用了android-ndk-r10e很長一段時間，但只是使用Android Studio的SDK Manager更新到最新版本的NDK。我注意到它的進展，並指出它是r12版本，也是它安裝的根目錄，但是當我去尋找它時，我找不到任何看起來像我原始安裝的東西。

當我最初安裝r10e，它安裝到文件夾的名字是/是：

/android-ndk-r10e 

下面是我CHANGELOG.md，我在更新似乎是目錄的NDK束文件夾中找到被安裝。似乎清楚，r12b已安裝，但在哪裏？不應該有一個「android-ndk-r12b」文件夾嗎？

Changelog 
========= 

Report issues to [GitHub]. 

[GitHub]: https://github.com/android-ndk/ndk/issues 

Announcements 
------------- 

* `ndk-build` will default to using Clang in r13. GCC will be removed in a 
    later release. 
* `make-standalone-toolchain.sh` will be removed in r13. Make sure 
    `make_standalone_toolchain.py` suits your needs. 

r12b 
---- 

* `ndk-gdb.py` has been fixed: https://github.com/android-ndk/ndk/issues/118 
* NdkCameraMetadataTags.h has been updated to no longer contain the invalid 
    enum value. 
* A bug in `ndk-build` that resulting in spurious warnings for static libraries 
    using libc++ has been fixed: 
    https://android-review.googlesource.com/#/c/238146/ 
* The OpenSLES headers have been updated for android-24. 

NDK 
--- 
* Removed support for the armeabi-v7a-hard ABI. See the explanation in the 
    [documentation](docs/HardFloatAbi.md). 
* Removed all sysroots for pre-GB platform levels. We dropped support for them 
    in r11, but neglected to actually remove them. 
* Exception handling when using `c++_shared` on ARM32 now mostly works (see 
    [Known Issues](#known-issues)). The unwinder will now be linked into each 
    linked object rather than into libc++ itself. 
* Default compiler flags have been pruned: 
    https://github.com/android-ndk/ndk/issues/27. 
    * Full changes here: https://android-review.googlesource.com/#/c/207721/5. 
* Added a Python implementation of standalone toolchains: 
    `build/tools/make_standalone_toolchain.py`. 
    * Windows users: you no longer need Cygwin to use this feature. 
    * We'll be removing the bash flavor in r13, so test the new one now. 
* `-fno-limit-debug-info` has been enabled by default for Clang debug builds. 
    This should improve debugability with LLDB. 
* `--build-id` is now enabled by default. 
    * This will be shown in native crash reports so you can easily identify 
     which version of your code was running. 
* `NDK_USE_CYGPATH` should no longer cause problems with libgcc: 
    http://b.android.com/195486. 
* `-Wl,--warn-shared-textrel` and`-Wl,--fatal-warnings` are now enabled by 
    default. If you have shared text relocations, your app will not load on 
    Marshmallow or later (and have never been allowed for 64-bit apps). 
* Precompiled headers should work better: 
    https://github.com/android-ndk/ndk/issues/14 and 
    https://github.com/android-ndk/ndk/issues/16. 
* Unreachable ARM (non-thumb) STL libraries have been removed. 
* Added Vulkan support to android-24. 
* Added Choreographer API to android-24. 
* Added `libcamera2` APIs for devices with 
    `INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED` or above (see [Camera 
    Characteristics]). 

[Camera Characteristics]: https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics.html#INFO_SUPPORTED_HARDWARE_LEVEL 

Clang 
----- 

* Clang has been updated to 3.8svn (r256229, build 2812033). 
    * Note that Clang packaged in the Windows 64-bit NDK is actually 32-bit. 
* `__thread` should work for real this time. 

GCC 
--- 

* Synchronized with the ChromeOS GCC @ `google/gcc-4_9` r227810. 
* Backported coverage sanitizer patch from ToT (r231296). 
* Fixed libatomic to not use ifuncs: 
    https://github.com/android-ndk/ndk/issues/31. 

Binutils 
-------- 

* "Erratum 843419 found and fixed" info messages are silenced. 
* Introduced option '--long-plt' to fix internal linker error when linking huge 
    arm32 binaries. 
* Fixed wrong run time stubs for AArch64. This was causing jump addresses to be 
    calculated incorrectly for very large DSOs. 
* Introduced default option '--no-apply-dynamic' to work around a dynamic 
    linker bug for earlier Android releases. 
* NDK r11 KI for `dynamic_cast` not working with Clang, x86, `stlport_static` 
    and optimization has been fixed. 

GDB 
--- 

* Updated to GDB 7.11: https://www.gnu.org/software/gdb/news/. 
* Some bugfixes for `ndk-gdb.py`. 

Known Issues 
------------ 

* This is not intended to be a comprehensive list of all outstanding bugs. 
* x86 ASAN still does not work. See discussion on 
    https://android-review.googlesource.com/#/c/186276/ 
* Exception unwinding with `c++_shared` still does not work for ARM on 
    Gingerbread or Ice Cream Sandwich. 
* Bionic headers and libraries for Marshmallow and N are not yet exposed 
    despite the presence of android-24. Those platforms are still the Lollipop 
    headers and libraries (not a regression from r11). 
* RenderScript tools are not present (not a regression from r11):

Answer 1

我終於明白了。在這裏回答我自己的問題。顯然，安裝更新ndk時，會在您的SDK安裝文件夾中放入一個「ndk-bundle」文件夾。這就是你應該在Android Studio項目中引用的內容。我現在更新到r12b版本的NDK如下：

.../android-sdk-macosx/ndk-bundle
