Question

我正在尝试创建一个使用recyclerview的库，然后将该库，即。，arr文件导入应用程序项目。

我在库的gradle文件中所做的更改是

apply plugin：'com.android.library'
删除了 applicationId
然后生成 aar 文件

库的gradle文件有一个依赖项列表

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.2.0'
compile 'com.android.volley:volley:1.0.0'
compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'com.android.support:recyclerview-v7:24.2.0'

}

现在我将aar文件导入我的应用程序。当我尝试访问包含recyclerview的活动时，应用程序崩溃了以下错误...

请帮助摆脱这个错误。我想访问我在库中包含的其他库，即排球和滑行。

提前致谢。

Answer 1

您的app-build似乎不知道您的库需要com.android.support:appcompat-v7:24.2.0所以它没有打包到您的apk中。

您有两种选择：

如果您希望继续将您的图书馆作为简单的aar文件保留：
在您的应用中重新声明您库的所有依赖项
以其他方式包含您的库，因此gradle可以知道传递依赖项：
- Gradle Module Dependency
- Maven Dependency
- 常春藤依赖

Answer 2

如果要将库发布到工件库，则需要配置publish gradle命令以添加库所具有的依赖项。在Bintray，我这样做了

artifacts {
    archives generateSourcesJar
}

task generateSourcesJar(type: Jar) {
    from android.sourceSets.main.java.srcDirs
    classifier 'sources'
}

然后你只需要告诉gradle你正在使用你的库包含的类。你可以这样做

compile('com.yourpage:yourlibrary:1.0.0'){
    transitive=true
}

导入应用程序后，无法在arr文件中使用依赖项
