Question

我观看了视频 http://ph0b.com/android-studio-gradle-and-ndk-integration/

看起来我的问题出在我的build.gradle和Android.mk文件中

我正在尝试将预构建的库（.so）集成到Android NDK中。 - 我创建了一个src / main / jni - 我放了所有的.cpp文件 - 我也有src / main / jniLibs目录，我有每个架构的.so文件。 - 我已将local.properties指向我的sdk和我的ndk目录。 - 我知道Android会在debug目录下创建一个Android.mk文件，并在每个架构的src / main / libs中创建一个libs文件夹。 _我正在使用带有sdk 19.1的Android Studio 1.01。我在libs目录下看到armeabiv7a和armeabi。我猜测Android创建了这些库。

**我收到以下错误： FAILURE：构建因异常而失败。 * 什么地方出了错：任务'：app：buildNative'执行失败。

处理'命令'Documents / android_development / android-ndk-r10d / ndk-build''以非零退出值2结束 *尝试：使用--stacktrace选项运行以获取堆栈跟踪。使用--info或--debug选项运行以获得更多日志输出。**

我的问题是： - 我的jni目录中是否需要我的Android.mk文件版本？ - 我知道我必须修改build.gradle，我在这里缺少什么？ - 我想使用intel HAXM测试模拟器。如何使用mac查看intel HAXM的cFlags。

我的build.gradle：

如果我的理解不对，请纠正我。我观看了视频，这是我在发布问题之前做的第一件事。这是最好的视频之一。我认为做gradle的重点是避免这种手动构建。我已经在我的

中加入了ndk-build

task buildNative(type: Exec, description: 'Compile JNI source via  NDK') 
{
    def ndkDir = android.plugin.ndkFolder
    commandLine "$ndkDir/ndk-build",
        '-C', file('src/main/jni').absolutePath, 
    // Change src/main/jni the relative path to your jni source
        '-j', Runtime.runtime.availableProcessors(),
        'all',
        '-d',
        'NDK_DEBUG=1'
}

我想知道是否必须在build.gradle或Android.mk中添加任何语句。谢谢！

AndroidStudio NDK使用gradle预构建库 - 错误执行失败，任务'：app：buildNative'
