问题
I am trying to create a library, that uses recyclerview, and then importing that library ie., arr file to an application project.
Changes i did in the library's gradle file are
- apply plugin: 'com.android.library'
- removed the applicationId
- And then generated aar file
The library's gradle file has a list of dependencies
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'
}
Now i imported the aar file to my app. When i try to access the activity containing the recyclerview, the app crashes the following err...

Please help to get rid of this error. I want to access the other libraries that i include in the library ie volley and glide.
Thanks in advance.
回答1:
It seems like your your app-build does not know your library needs com.android.support:appcompat-v7:24.2.0 so it's not packaged into your apk.
You have two options:
- If you want to stay with including your library as simple aar file:
Redeclare all dependencies of your library in your app - Include your library in another way, so gradle can know the transitive dependencies:
- Gradle Module Dependency
- Maven Dependency
- Ivy Dependency
回答2:
If you're publishing your library to an artifactory repository, you need to configure your publish gradle commands to add the dependencies your library has. In Bintray I do it in this way
artifacts {
archives generateSourcesJar
}
task generateSourcesJar(type: Jar) {
from android.sourceSets.main.java.srcDirs
classifier 'sources'
}
Then you only need to tell gradle that you're using the classes that your library contains. You can do it in this way
compile('com.yourpage:yourlibrary:1.0.0'){
transitive=true
}
