“：应用程序：buildNative”. > execCommand == null！”,即可在Android Studio中使用NDK构建我的应用程序.是什么原因造成的如何进一步处理？

概述这是我尝试在androidstudio中构建我的android应用程序时遇到的错误.该应用程序使用的是NDK,我认为是导致问题的原因.我是androidstudio的新手,现在已经处理此问题大约2周了.经过大量的搜寻后,我不知道问题是什么/如何解决这个问题,也不清楚发生了什么.我也无法弄清楚如何在build.

这是我尝试在android studio中构建我的androID应用程序时遇到的错误.该应用程序使用的是NDK,我认为是导致问题的原因.我是androID studio的新手,现在已经处理此问题大约2周了.经过大量的搜寻后,我不知道问题是什么/如何解决这个问题,也不清楚发生了什么.我也无法弄清楚如何在build.gradle文件上使用调试器,或者如何查看System.env.ANDROID_NDK_HOME的值.我似乎被困在墙上,所以任何帮助/建议都值得赞赏.

Error:Gradle: Execution Failed for task ':app:buildNative'.execCommand == null!

这是build.gradle中的buildNative任务.

task buildNative(type: Exec) {    if (System.env.ANDROID_NDK_HOME != null) {        def ndkBuild = new file(System.env.ANDROID_NDK_HOME, 'ndk-build')        commandline ndkBuild    } else {        dolast {            println '##################'            println 'SkipPing NDK build'            println 'Reason: ANDROID_NDK_HOME not set.'            println '##################'        }    }}

这是堆栈跟踪

解决方法:

错误：未定义System.env.ANDROID_NDK_HOME仅仅意味着您必须：

(假设您使用运行bash shell的终端运行linux)：

export ANDROID_NDK_HOME=/opt/androID-ndk

(其中/ opt / androID-ndk是NDK目录的完整路径),然后在当前shell中启动AndroID Studio.如果从桌面启动AndroID Studio,则必须将上述行添加到.bashrc登录环境中.

但是,如果使用windows,则必须使用控制面板为NDK目录设置环境变量.
