Android Studio - 导入 Simple-Xml 库 [英] Android Studio - Importing Simple-Xml library

问题描述

我对我的 Android Studio IDE 快要疯了.

我愿意从 Central (v2.7.1) 添加 Maven 库 simple-xml

1. 项目编译良好

2. Gradle 在它的 build.gradle 中有 lib 依赖:

   依赖项{编译'com.android.support:appcompat-v7:18.0.0'编译'org.simpleframework:simple-xml:2.7.1'}

3. 在 Android Studio 的模块设置中为 simple-xml 库检查导出:

当我运行我的应用程序时，我找不到类......

<块引用>

java.lang.NoClassDefFoundError: org.simpleframework.xml.core.Persister

我迷路了，听起来 Gradle 由于某些原因没有在 apk 中打包 lib 和依赖项......

Edit1:我的 Android Studio 版本是 0.2.13(最新)，Gradle 0.5.+

Edit2:我使用的完整 build.gradle

buildscript {存储库{MavenCentral()}依赖{类路径 'com.android.tools.build:gradle:0.5.+'}}应用插件:'android'存储库{MavenCentral()}安卓 {compileSdkVersion 17构建工具版本17.0.0"默认配置{minSdk 版本 14目标SDK版本18}}依赖{编译'com.android.support:appcompat-v7:18.0.0'编译'org.simpleframework:simple-xml:2.7.1'}

解决方案

我发现了问题.

正如我所料，这是 graddle 插件 0.5.+.

带有 gradle 插件 0.6.+ (Gradle 1.8) 的 Android Studio 0.3.0 现在修复了这个问题.

但是，我使应用程序以这种方式与 Android Studio 0.2.13 和 gradle 插件 0.5 配合使用:

由于 gradle 插件拒绝从 maven central 部署库，我将库和依赖项下载到我的项目的 lib 目录中.我将项目设置为使用该库作为项目 lib 目录中的本地库.

解决方法的说明:

1. 在模块设置中删除我项目中对 simple-xml(maven 中心)的所有引用

2. 将 simple-xml-2.7.1.jar、stax-1.2.0.jar、stax-api-1.0.1.jar 和 xpp3-1.1.3.3.jar 复制到我的项目中的 lib 目录

3. 在我的项目中选择 lib simple-xml-2.7.1.jar 并使用 Add as Library 上下文菜单导入 lib

4. 像这样更改 build.gradle:

   依赖项{

   编译'com.android.support:appcompat-v7:18.0.0'编译文件('simple-xml-2.7.1.jar')

   }

注意:不要包含依赖项，否则会与 Grzegorz 提到的 Android 系统产生冲突

I am going crazy with my Android Studio IDE.

I am willing to add the Maven library simple-xml from Central (v2.7.1)

1. The project compiles well

2. Gradle has the lib dependency in its build.gradle:

   dependencies {
     compile 'com.android.support:appcompat-v7:18.0.0'
     compile 'org.simpleframework:simple-xml:2.7.1'
   }
   

3. Export is checked in Android Studio's Module Settings for the simple-xml lib:

And I got the Class not found when I run my app ...

java.lang.NoClassDefFoundError: org.simpleframework.xml.core.Persister

I am lost, It sounds like Gradle doesn't pack the lib and dependencies in the apk for some reasons ...

Edit1: my Android Studio version is 0.2.13 (latest), Gradle 0.5.+

Edit2: full build.gradle I use

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 18
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:18.0.0'
    compile 'org.simpleframework:simple-xml:2.7.1'
}

解决方案

I found the problem.

It was the graddle plugin 0.5.+ as I expected.

The Android Studio 0.3.0 with gradle plugin 0.6.+ (Gradle 1.8) now fixes the problem.

However, I made the application to work with the Android Studio 0.2.13 and gradle plugin 0.5 this way:

As the gradle plugin refuses to deploy the library from maven central, I downloaded the library and dependencies to the lib directory of my project. I setup the project to use the library as a local one in the lib directory of the project.

Directions for the workaround:

1. remove all references in my project to simple-xml (maven central) in Module Settings

2. Copy simple-xml-2.7.1.jar, stax-1.2.0.jar, stax-api-1.0.1.jar and xpp3-1.1.3.3.jar to lib directory in my project

3. Select the lib simple-xml-2.7.1.jar in my project and Import the lib using Add as Library contextual menu

4. Change the build.gradle like this:

   dependencies {

   compile 'com.android.support:appcompat-v7:18.0.0'
   
   compile files('simple-xml-2.7.1.jar')
   

   }

Note: do not include the dependencies, otherwise they will create conflicts with the Android system as mentionned by Grzegorz
