Hello guys I'm trying to learn about openCV in android I've already following the instruction given here

but when I'm trying to compile I'm only getting

01:50:14 Build Finished (took 184ms)

in the console and I'm also get an error

Errors occurred during the build. Errors running builder 'CDT Builder' on project 'org.opencv.samples.fd.FdActivity'. Internal error building project org.opencv.samples.fd.FdActivity configuration Default java.lang.NullPointerException Internal error building project org.opencv.samples.fd.FdActivity configuration Default java.lang.NullPointerException

Solution

  • try

    Project Properties>C/C++ Build>Tool Chain Editor

    Current toolchain: Android GCC
    Current builder: Android Builder

    Project Properties>C/C++ Build

    (uncheck) use default build command
    Build command: ndk-build
    (uncheck) generate Makefiles automatically
