2013-10-30 05:29:53 -0600 | commented question | I can't compile JNI file I'm very frustrated. I don't know what to do. I went through all steps thousand times. I don.t know why ndk-build wont find android file. Very strange is, if I compile with ndk-build OpencCv samples it's build normaly. ndk-build finds all file. I also try include complete path to algorithme file in core file. But then I get error to find next file include in algorithm file. |
