我在这个预构建的 library.mk 文件中收到 NDK 中止停止错误。上面给出了文件。它还显示未能构建 NDK 和 NDK-build 以非零退出值 2 完成。

我该如何解决这个错误？

提前致谢。

注意：如果您已经创建了项目，然后通过 SDK 工具安装 Android NDK、CMake 和 LLDB，那么您的项目可能无法构建，即在 Make 时会出现错误项目.

按照以下步骤操作：

安装AndroidNDK、CMake和LLDB
在 Android 中创建新项目并选中 包括 C++ 支持
最后启用异常支持 & 运行时类型信息支持
按完成。

在应用级别 build.gradle 文件中。

在 apply plugin:...

之前添加以下行

import org.apache.tools.ant.taskdefs.condition.Os

Properties properties = new Properties()
properties.load(project.rootProject.file('local.properties').newDataInputStream())
def ndkDir = properties.getProperty('ndk.dir')

加入android->defaultConfig

externalNativeBuild{ 制作{ cppFlags“-frtti -fexceptions” } }
在 buildTypes {} 标签后添加以下行

externalNativeBuild { 制作{ 路径 "CMakeLists.txt" } } 任务 ndkBuild（类型：执行）{ 如果（Os.isFamily（Os.FAMILY_WINDOWS））{ 命令行 ndkDir + '/ndk-build.cmd', '-C', file('src/main').absolutePath } 别的 { 命令行 ndkDir + '/ndk-build', '-C', file('src/main').absolutePath } }

tasks.withType(JavaCompile) { compileTask -> compileTask.dependsOn ndkBuild }

希望对您有所帮助。 !!
