带有本机库错误的 Android Studio Gradle [英] Android Studio Gradle with native libs error

问题描述

对不起我的英语...

我有最后一个 android studio(2013 年 6 月 14 日).创建新的 Android 项目.将 .so 文件添加到/libs/armeabi

I have last android studio (14 june 2013). Create new Android project. Add .so files to /libs/armeabi

将 build.gradle 编辑为

Edit build.gradle to

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.4'
    }
}
apply plugin: 'android'

dependencies {
    compile files('libs/android-support-v4.jar','libs/jcPKCS11.jar')
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 16
    }
}

task copyNativeLibs(type: Copy) {
    from(new File(project(':JaCertTest').getProjectDir(), 'libs/armeabi'))  { include '**/*.so' }
    into new File(buildDir, 'native-libs')
}

tasks.withType(Compile) { compileTask -> compileTask.dependsOn copyNativeLibs }

clean.dependsOn 'cleanCopyNativeLibs'

tasks.withType(com.android.build.gradle.tasks.PackageApplication) { pkgTask ->
    pkgTask.jniDir new File('build/native-libs')
}

我收到一个错误:FAILURE:构建失败，出现异常.

I received an error: FAILURE: Build failed with an exception.

• 出了什么问题:任务':JaCertTest:packageDebug'的配置发现问题.
  • What went wrong: A problem was found with the configuration of task ':JaCertTest:packageDebug'.

    为属性jniDir"指定的目录build\native-libs"不存在.

  Directory 'build\native-libs' specified for property 'jniDir' does not exist.

  推荐答案

  如果您的 copyNativeLibs 任务未能找到任何文件，因此不会创建build\native-libs"目录，则会发生这种情况.你确定你的libs/armeabi"目录下有 .so 文件吗?

  This will happen if your copyNativeLibs task fails to find any files, and therefore doesn't create the "build\native-libs" directory. Are you sure that there are .so files in your "libs/armeabi" directory?

  另外，请记住，您的脚本实际上不会编译本机代码.您仍然需要自己通过运行 ndk-build 来生成 .so 库.

  Also, keep in mind that your script won't actually compile the native code. You still need to do that yourself by running ndk-build to generate the .so libraries.

  以下是如何让脚本编译本机代码的示例.请注意，这要求 ndk-build 在您的 PATH 中.

  Here is an example of how to get your script to compile your native code. Note, this requires that ndk-build is in your PATH.

  // Task to run ndk-build
  task ndkBuild(type: Exec) {
      commandLine 'ndk-build', '-j', Runtime.runtime.availableProcessors()
  }
  
  task copyNativeLibs(type: Copy) {
      from(new File(project(':JaCertTest').getProjectDir(), 'libs/armeabi'))  { include '**/*.so' }
      into new File(buildDir, 'native-libs')
  }
  
  // Make copyNativeLibs depend on ndkBuild since we must build the libraries
  // before we can copy them.
  copyNativeLibs.dependsOn 'ndkBuild'
  tasks.withType(Compile) { compileTask -> compileTask.dependsOn copyNativeLibs }
  
  clean.dependsOn 'cleanCopyNativeLibs'
  
  tasks.withType(com.android.build.gradle.tasks.PackageApplication) { pkgTask ->
      pkgTask.jniDir new File('build/native-libs')
  }
