How do I know which version of a .so my APK is running? (armeabi-v7a or armeabi)

According to my Application.mk, I am compiling both a armeabi-v7a AND a armeabi version of a C++ shared library. How do I know which version is being loaded at runtime? Is there a similar setting for the Java code, or is that an ill-formed question?

if you want to know it in native code, than try doing like in hello-jni ndk sample android-ndk\samples\hello-jni\jni\hello-jni.c

#if defined(__arm__)
  #if defined(__ARM_ARCH_7A__)
    #if defined(__ARM_NEON__)
      #if defined(__ARM_PCS_VFP)
        #define ABI "armeabi-v7a/NEON (hard-float)"
      #else
        #define ABI "armeabi-v7a/NEON"
      #endif
    #else
      #if defined(__ARM_PCS_VFP)
        #define ABI "armeabi-v7a (hard-float)"
      #else
        #define ABI "armeabi-v7a"
      #endif
    #endif
  #else
   #define ABI "armeabi"
  #endif
#elif defined(__i386__)
   #define ABI "x86"
#elif defined(__x86_64__)
   #define ABI "x86_64"
#elif defined(__mips64)  /* mips64el-* toolchain defines __mips__ too */
   #define ABI "mips64"
#elif defined(__mips__)
   #define ABI "mips"
#elif defined(__aarch64__)
   #define ABI "arm64-v8a"
#else
   #define ABI "unknown"
#endif

    return (*env)->NewStringUTF(env, "Hello from JNI !  Compiled with ABI " ABI ".");

Check your Processor Architecture using android framework api. According to that particular .so loaded.
