NDK使用遇到的那些事(持续更新当中)

:AppCamera:transformNativeLibsWithStripDebugSymbolForDebug

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':AppCamera:transformNativeLibsWithStripDebugSymbolForDebug'.
> A problem occurred starting process 'command 'D:\devTools\AndroidSDK\ndk-bundle\toolchains\mips64el-linux-android-4.9\prebuilt\windows-x86_64\bin\mips64el-linux-android-strip''

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

原因是升级NDK(android-ndk-r17-windows-x86_64)最新版本之后找不到ndk-bundle\toolchains\mips64el-linux-android-4.9\prebuilt\windows-x86_64\bin\mips64el-linux-android-导致的,删除升级之后的NDK版本，如果是通过AS中升级的最好在AS中删除，然后在下载旧版本的NDK，以下是android-ndk-r16b下载地址:

https://dl.google.com/android/repository/android-ndk-r16b-windows-x86.zip
https://dl.google.com/android/repository/android-ndk-r16b-windows-x86_64.zip
https://dl.google.com/android/repository/android-ndk-r16b-darwin-x86_64.zip
https://dl.google.com/android/repository/android-ndk-r16b-linux-x86_64.zip

下载完成解压到之前的目录即可,运行即可，如果此时运行还报错，请继续往下读

  Error while executing process D:\devTools\AndroidSDK\cmake\3.6.4111459\bin\cmake.exe with arguments {--build F:\workplace\duanbinbin\pano-share-sdk-android\PanoShareSDKAndroid\DemoJNI\.externalNativeBuild\cmake\debug\armeabi-v7a --target link}
  [1/1] Re-running CMake...
  CMake Warning at D:/devTools/AndroidSDK/ndk-bundle/build/cmake/android.toolchain.cmake:63 (message):
    Using custom NDK path (ANDROID_NDK is set):
    D:\devTools\AndroidSDK\ndk-bundle
  Call Stack (most recent call first):
    F:/workplace/duanbinbin/pano-share-sdk-android/PanoShareSDKAndroid/DemoJNI/.externalNativeBuild/cmake/debug/armeabi-v7a/CMakeFiles/3.6.0-rc2/CMakeSystem.cmake:6 (include)
    CMakeLists.txt

解决方式如下:

• 在项目目录下\app.externalNativeBuild\cmake中找到CMakeSystem.cmake文件
  

• 打开CMakeSystem.cmake文件,找到红色圆圈中的文件
  

• 编辑android.toolchain.cmake文件，查找# Toolchain.关键字

# Toolchain.
if(CMAKE_HOST_SYSTEM_NAME STREQUAL Linux)
  set(ANDROID_HOST_TAG linux-x86_64)
elseif(CMAKE_HOST_SYSTEM_NAME STREQUAL Darwin)
  set(ANDROID_HOST_TAG darwin-x86_64)
elseif(CMAKE_HOST_SYSTEM_NAME STREQUAL Windows)
   #set(ANDROID_HOST_TAG windows-x86_64)
   set(ANDROID_HOST_TAG windows)
endif()

修改set(ANDROID_HOST_TAG windows-x86_64)为set(ANDROID_HOST_TAG windows)即可。
