NDK示例原生音频：无法找到＆＃34; libnative-audio-jni.so＆＃34;

Question

我正在android studio中使用NDK来完成我的新项目。我刚刚安装了NDK并在名为native-audio的NDK包中导入了一个示例项目。我尝试了几次来运行该项目，但它仍然返回

apply plugin: 'com.android.model.application'
model {
android {
    compileSdkVersion 21
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.example.nativeaudio"
        minSdkVersion.apiLevel 9
        targetSdkVersion.apiLevel 9

        buildConfigFields {
            create() {
                type "int"
                name "VALUE"
                value "1"
            }
        }

        ndk {
            moduleName "native-audio-jni"
        }
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles.add(file("proguard-rules.pro"))
        }
    }
     //    productFlavors {
   //        create("flavor1") {
//            applicationId "com.example.nativeaudio"
//        }
//    }

    // Configures source set directory.
    sources {
        main {
            java {
                source {
                    srcDir "src"
                }
            }
        }
    }

}
}

如果有人能弄清楚事情并解释实际上该代码会发生什么，那将对我有很大的帮助。我已经完成了StackOverflow中几乎所有可用的链接，但没有希望获得好处。

修改 应用程序/的build.gradle

   // Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle-experimental:0.6.0-alpha5'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

的build.gradle

def simulate1(theta):
    # introduce evil random displacement
    theta = theta + random.uniform(-noise, noise)

    # apply stipid physics laws
    f = math.sin(theta)
    theta = theta + f*dt

    return theta

#
# simulate evolution of the system during so many ticks
#
def simulate(theta, ticks):
    thetas = []
    for _ in range(ticks):
            theta = simulate1(theta)
            thetas.append(theta)

    return thetas
