I am getting NDK Aborting Stop error in this prebuilt-library.mk file. The file is given above. It's also showing failed to build NDK & NDK-build finished with non zero exit value 2.

How can I fix this error?

Thanks in advance.

Answer 1

Note: If you already created project and after that you are installing Android NDK, CMake and LLDB through SDK Tools then your project might not build ie you will get an error while Make Project .

Follow the below steps:

1. Install Android NDK, CMake and LLDB
2. Create New Project in Android and checked Include C++ Support
3. At last Enable Exception Support & Runtime Type information Support
4. Press to Finish.

In app level build.gradle file.

• Add below lines before your apply plugin:...

   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') 

• Add in android -> defaultConfig

  externalNativeBuild{ cmake{ cppFlags "-frtti -fexceptions" } }

• Add below lines after buildTypes {} tag

  externalNativeBuild { cmake { path "CMakeLists.txt" } } task ndkBuild(type: Exec) { if (Os.isFamily(Os.FAMILY_WINDOWS)) { commandLine ndkDir + '/ndk-build.cmd', '-C', file('src/main').absolutePath } else { commandLine ndkDir + '/ndk-build', '-C', file('src/main').absolutePath } }

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

Hope it helps you. !!
