Question

Please assist me for using libxml2 native-lib - XML parsing library in Android NDK using CMakeLists.txt configura

Answer 1

After some search and effort i found some solution. So i would like to answer my own question in following steps :

1. Clone the source from android/platform_external_libxml2 in your machine.

2.Add the required all source as well as header files at appropriate place in your project.

3.With the help of Android.bp file, i managed to configure my app/CMakeList.txt

4.Configure your app or library level build.gradle file.

Here is My CMakeLists.txt :

                cmake_minimum_required(VERSION 3.4.1)

                set(LIBXML2_SOURCES

                src/main/cpp/libxml2/src/schematron.c
        )

        include_directories(src/main/cpp/libxml2/include)

        include_directories(src/main/cpp/libxml2/src)

        add_library( # Sets the name of the library.
         myexampe-native

         # Sets the library as a shared library.
         SHARED

         # Provides a relative path to your source file(s).
         src/main/cpp/my-native.cpp )

         add_library( # Sets the name of the library.
         mylibxml2

         # Sets the library as a shared library.
         SHARED

         # Provides a relative path to your source file(s).
         ${LIBXML2_SOURCES} )

         target_link_libraries( # Specifies the target library.

                   myexampe-native

                   mylibxml2
                   )

And Here is my app/build.gradle configuration

              android { .....
              defaultConfig { .....

              externalNativeBuild {
        cmake {
            cppFlags "-std=gnu++11"
            arguments '-DANDROID_PLATFORM=android-21',
                      '-DANDROID_STL=c++_shared','-DANDROID_ARM_MODE=arm'

        }
    }

Comments are welcomed for any clarification. Thanks :-)
