(这里AccessQRat是创建的project的名称)
问题原因
我的ndk文件夹android-21下文件不全,但是android-24文件夹文件是全的,然而cmake默认选择了21,虽然我也不知道为什么就选择了21
解决方法
首先确认自己哪一个ndk版本是全的,找到ndk-build/platforms文件夹下,android-xx 后面的xx代表数字,即platmform的版本,根据我这里的提示,显然我的21版本的NDK有文件有问题,所以我选择换一个版本,因为我发现我24的版本是全的,具体的可以使用readelf命令来查看那几个文件是不是完整有效的.
找到ndk-build下cmake,进入
cd ~/Sdk/cmake/3.6.3155560/#使用vim进行编辑,也可以使用其他进行编辑vim android.toolchain.cmake找到关于PLATFORM和PLATFORM_LEVEL的那几个语句,
if(ANDROID_PLATFORM MATCHES "^android-([0-8]|10|11)$") set(ANDROID_PLATFORM android-9)elseif(ANDROID_PLATFORM STREQUAL android-20) set(ANDROID_PLATFORM android-19)elseif(NOT ANDROID_PLATFORM) set(ANDROID_PLATFORM android-9)endif()string(REPLACE "android-" "" ANDROID_PLATFORM_LEVEL ${ANDROID_PLATFORM})if(ANDROID_ABI MATCHES "64(-v8a)?$" AND ANDROID_PLATFORM_LEVEL LESS 21) set(ANDROID_PLATFORM android-21) set(ANDROID_PLATFORM_LEVEL 21)endif()if(NOT ANDROID_STL) set(ANDROID_STL gnustl_static)endif()这里可以猜到是通过set来set版本,所以我最终选择不让他自动判断,直接强行设置为24,即在这段后面添加两个set语句
if(ANDROID_PLATFORM MATCHES "^android-([0-8]|10|11)$") set(ANDROID_PLATFORM android-9)elseif(ANDROID_PLATFORM STREQUAL android-20) set(ANDROID_PLATFORM android-19)elseif(NOT ANDROID_PLATFORM) set(ANDROID_PLATFORM android-9)endif()set(ANDROID_PLATFORM android-24)set(ANDROID_PLATFORM_LEVEL 24)string(REPLACE "android-" "" ANDROID_PLATFORM_LEVEL ${ANDROID_PLATFORM})if(ANDROID_ABI MATCHES "64(-v8a)?$" AND ANDROID_PLATFORM_LEVEL LESS 21) set(ANDROID_PLATFORM android-21) set(ANDROID_PLATFORM_LEVEL 21)endif()if(NOT ANDROID_STL) set(ANDROID_STL gnustl_static)endif()回到android studio 重新sync一次,万事大吉.
