我在此prebuilt-library.mk文件中收到NDK Aborting Stop错误。该文件在上面给出。它也显示未能建立NDK＆amp; NDK-build以非零退出值2完成。

如何解决此错误？

提前致谢。

Answer 1

注意：如果您已经创建了项目，之后您通过SDK工具安装了Android NDK，CMake和LLDB，那么您的项目可能无法构建，即 Make Project 时会出现错误。

按照以下步骤操作：

1. 安装Android NDK，CMake和LLDB
2. 在Android中创建新项目并选中包含C ++支持
3. 最后启用例外支持＆amp; 运行时类型信息支持
4. 按完成。

在应用级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 - ＆gt; defaultConfig

  externalNativeBuild {     cmake的{         cppFlags＆＃34; -frtti -fexceptions＆＃34;     } }

• 在buildTypes {}代码

  之后添加以下行

  externalNativeBuild {     cmake {         路径＆＃34; CMakeLists.txt＆＃34;     } } task ndkBuild（type：Exec）{     if（Os.isFamily（Os.FAMILY_WINDOWS））{         commandLine ndkDir +＆＃39; /ndk-build.cmd' ;,＆＃39; -C＆＃39;，file（＆＃39; src / main＆＃39;）。absolutePath     } else {         commandLine ndkDir +＆＃39; / ndk-build＆＃39;，＆＃39; -C＆＃39;，file（＆＃39; src / main＆＃39;）。absolutePath     } }

  tasks.withType（JavaCompile）{     compileTask - ＆gt; compileTask.dependsOn ndkBuild }

希望它对你有所帮助。 !!
