how to rewrite the Makefile into android.mk?

半世苍凉 提交于 2019-12-18 11:34:41
问题 In my new project, I need to base on a c written project. And I know that I can use the NDK to do it, but here is a question: how to rewrite the standard Makefile into the Android.mk ? And further more, in Android, can I, neglecting the ndk, build the project directly using the jni to adapt the c project into the android project? And anymore idea to adapt the c project into the android project? thx. At last, here is the Makefile: # Makefile.in generated by automake 1.10.1 from Makefile.am. #

I created a class named Config, which contains all of the application's constants such as ball sizes and fps. Below is how I arranged the code. Config.h #ifndef __CONFIG_H_ // this was auto-generated by eclipse #define __CONFIG_H_ class Config { public: static const double GRAVITY;

Android NDK OpenCV - Invalid Arguments for substr

An example: #include <string> #include <vector> using namespace std; using namespace cv; ... std::string str="We think in generalities, but we live in details."; std::string str2 = str.substr (12,12); does the compiler quit for substr with: Invalid arguments ' Candidates are: std::basic_string

On ndk-built, it results in error which is as below Prebuilt : libMyaccessories.so <= jni/ Install :
