Answer 1

Refer this answer by @Tundebabzy if you are using ndk-build build system.

For CMake build system

add the following to your module-level build.gradle file:

android {
  ...
  defaultConfig {
    ...
    externalNativeBuild {

      // For ndk-build, instead use ndkBuild {}
      cmake {
        // Enables exception-handling support.
        cppFlags "-fexceptions"
      }
    }
  }
}
...

Just a note for anyone who has started with one of the NDK examples.

They tend to set -fno-exceptions in their CMakeLists.txt, you need to remove it:

set(CMAKE_CXX_FLAGS  "${CMAKE_CXX_FLAGS} -Wall -Werror -fno-exceptions -frtti") 

You might want to check whether you want -Werror while you're at it.
