Adding try catch to native code

I am getting an exception from the native code .

With the stack trace i am not getting much info than the function name.

So i am trying to add a try catch to throw a java exception .

Is this possible

i added 

try{

 

}

catch (const std::exception& e)                                 \     {                                                               \       /* unknown exception */                                       \       jclass jc = env->FindClass("java/lang/Error");                \       if(jc) env->ThrowNew (jc, e.what());                          \     }to  Java_com_idg_reelbillboard_CloudRecognition_CloudReco_enterScanningModeNative function But on compilation i am getting   Compile++ arm    : CloudReco <= CloudReco.cppjni/CloudReco.cpp: In function 'void Java_com_idg_reelbillboard_CloudRecognition_CloudReco_enterScanningModeNative(JNIEnv*, _jobject*)':jni/CloudReco.cpp:737: error: expected unqualified-id before '&' tokenjni/CloudReco.cpp:737: error: exception handling disabled, use -fexceptions to enablejni/CloudReco.cpp:737: error: expected ')' before '&' tokenjni/CloudReco.cpp:737: error: expected '{' before '&' tokenjni/CloudReco.cpp:737: error: 'e' was not declared in this scopejni/CloudReco.cpp:737: error: expected ';' before ')' token/cygdrive/c/Users/IDG3/android-ndk-r8-windows/android-ndk-r8/build/core/build-binary.mk:243: recipe for target `obj/local/armeabi/objs/CloudReco/CloudReco.o' failedmake: *** [obj/local/armeabi/objs/CloudReco/CloudReco.o] Error 1  Please help on why it is coming.
