Android NDK 构建

Question

在尝试构建我的 android ndk 项目时出现以下错误。安卓工作室版本 3.1.3

FAILURE: Build failed with an exception.

• 出了什么问题:任务“:app:ndkBuild”执行失败。

  Process 'command '/Users/bnaskar/Library/Android/sdk/ndk-bundle/ndk-build'' finished with non-zero exit value 2

• 尝试:使用 --info 或 --debug 选项运行以获得更多日志输出。使用 --scan 运行以获得完整的见解。

• 异常(exception)是:

Answer 1

恐怕您使用已弃用的方式为您的项目构建本地库。新的 Android 插件 (v. 3.1.2) 使用 externalNativeBuild。查看official instructions for upgrading .

简而言之，你需要类似的东西

android { 
    externalNativeBuild {
        ndkBuild {
            path "Android.mk"
        }
    }
} 

在您的模块 build.gradle 中。

对于您的文件，结果可能如下所示:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 24
    buildToolsVersion "27.0.3"
    defaultConfig {
        applicationId "com.example.bnn.breakout"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        //testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    externalNativeBuild {
      ndkBuild {
        path 'src/main/jni/Android.mk'
      }
    }

    buildTypes {
        debug {
            debuggable true
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:24.2.1'
    implementation 'com.android.support:multidex:1.0.3'
    testImplementation 'junit:junit:4.12'
}
