Enable Exception C++

It depends on what runtime you are using. If you are not using system runtime and are building with ndk-build, you add any of these to your Android.mk file:

• LOCAL_CPP_FEATURES += exceptions (Recommended)
• LOCAL_CPPFLAGS += -fexceptions

Also, you can add the following line to your Application.mk file:

• APP_CPPFLAGS += -fexceptions

There's more information in docs/CPLUSPLUS-SUPPORT.html in your NDK folder

You need to build with CrystaX's custom NDK. It has full libstdc++, RTTI and exceptions support. It's generally the best tool for Android development I know.
