步骤二:实现JNI函数 我们需要编写一个 JNI 函数,该函数将 C++ 的string类型数据传递到__android_log_print中。以下是一个示例代码: #include<jni.h>#include<string>#include<android/log.h>#defineLOG_TAG"NativeLog"#defineLOGI(...)__android_log_print(ANDROID_LOG_INFO,LOG_TAG,__VA_ARGS__)extern"C...

C++标准流输出std::cout一直以来为人们所诟病:不灵活,格式化支持差,冗长等等。人们有此想法源于C库的printf()函数虽然不提供类型安全保障和线程安全保障,...
