AndroidStudio NDK编译配置_LINUX 以及 WIN64

说明：Android studio特殊性，win32客户端无法使用Cmake，但是Linux以及WIN64客户端可以使用Cmake，所以NDK开发针对Linux以及WIN64有几个方法
1. 使用google推荐的cmake
2. 使用传统方式

Cmake NDK开发案例：https://github.com/googlesamples/android-ndk

传统NDK开发配置跟WIN32大体一样
区别在于LINUX平台编译文件为ndk-build windows平台为ndk-build.cmd

**Linux:**
    tasks.withType(JavaCompile) {
        compileTask -> compileTask.dependsOn ndkBuild
    }

    task ndkBuild(type: Exec, description: 'Compile JNI source via NDK') {
        println('executing ndkBuild')
        def ndkBuildPath = android.ndkDirectory;
        commandLine "$ndkBuildPath/ndk-build", '-j8', '-C', file('src/main').absolutePath
    }

    task ndkClean(type: Exec, description: 'clean JNI libraries') {
        println('executing ndkBuild clean')
        def ndkBuildPath = android.ndkDirectory;
        commandLine "$ndkBuildPath/ndk-build", 'clean', '-C', file('src/main').absolutePath
    }

    clean.dependsOn 'ndkClean'

**window：**
    tasks.withType(JavaCompile) {
        compileTask -> compileTask.dependsOn ndkBuild
    }

    task ndkBuild(type: Exec, description: 'Compile JNI source via NDK') {
        println('executing ndkBuild')
        def ndkBuildPath = android.ndkDirectory;
        commandLine "$ndkBuildPath/ndk-build.cmd", '-j8', '-C', file('src/main').absolutePath
    }

    task ndkClean(type: Exec, description: 'clean JNI libraries') {
        println('executing ndkBuild clean')
        def ndkBuildPath = android.ndkDirectory;
        commandLine "$ndkBuildPath/ndk-build.cmd", 'clean', '-C', file('src/main').absolutePath
    }

    clean.dependsOn 'ndkClean'
