Question

我的android项目有问题，我从一台计算机移动到另一台计算机。当然，在我更改计算机和Android Studio版本（从1.5到2.2）之前，一切正常。现在，当我想运行项目时，我遇到了这个错误：

错误：任务＆＃39;：app：ndkBuild＆＃39;执行失败。处理＆＃39; e：\ Android \ ndk \ android-ndk-r12b \ ndk-build.cmd＆＃39;＆＃39;完成非零退出值2

这是我的gradle构建：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.xxx.crossexample"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"

        sourceSets.main {
            jniLibs.srcDir 'src/main/libs'
            jni.srcDirs = []
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    task ndkBuild(type: Exec) {
        Properties properties = new Properties()
        properties.load(project.rootProject.file('local.properties').newDataInputStream())
        def ndkDir = properties.getProperty('ndk.dir')
        commandLine "e:\\Android\\ndk\\android-ndk-r12b\\ndk-build.cmd", '-B', '-C', file('src/main/jni').absolutePath

    }

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

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.0'

}

我的local.properies

sdk.dir=e\:\\Android\\sdk
ndk.dir=e\:\\Android\\ndk\\android-ndk-r12b

我的代码有什么问题吗？

UPDATE 这是gradle控制台日志：

Answer 1

在我的情况下，从命令行运行构建工作正在运行，但不是来自gui。我通过升级Android Build工具解决了这个问题。也许NDK与之前的Android Build工具不兼容。
