如何在android-ndk项目中使用C ++类

Question

people! I am looking for an example or any advice, of how to use C++ classes in android-ndk project. There are a lot of examples, but they all written in pure C. And there are a lot of topics where people asking the same question. But there are stupid answers, or people who answering don't know that C and C++ are different languages ))) I have been searched a lot, I've also been on the 10th search page of google search ), but nothing found ) So, how to use C++ classes in android-ndk project? Please give an example like famous "hello world".

Problem is when I am including *.h file with class ndkclass { }; defined into it, I have got this error: expected '=', ',', ';', 'asm' or ' attribute ' before 'ndkclass'

Answer 1

Does your file has .cpp extension? If it has .c extension then compiler thinks your code is C, not C++, and that's why you will get error message.

Using C++ in android-ndk is same as in any other place (Visual C++, XCode, GCC, ...)
