该项目由3个模块(app,datecs和volley)组成。 datecs
模块是库libs/com.datecs.api.jar
之间的接口。问题是库类/包在应用程序模块中不可见。
以下是gradle文件:
project.gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
app.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion '28.0.3'
defaultConfig {
minSdkVersion 16
targetSdkVersion 26
versionCode 1
versionName "1.0"
}
buildTypes {
release {

}

如何在应用程序模块中访问库类?
答案 0 :(得分:1)
由于我无权访问您的特定库(datecs),因此我测试了一个应用程序模块和一个库模块,其中该应用程序模块需要从库模块中“导入” 'com.android.support:appcompat-v7:28.0.0'
依赖项。
使用api
而不是implementation
帮了我大忙。
应用模块的build.gradle中的依赖项关闭:
dependencies {
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation project(':mytestlibrary')
}
库模块的build.gradle中的依赖项关闭:
dependencies {
api 'com.android.support:appcompat-v7:28.0.0'
}
另请参阅api
上关于Dependency Configurations的文档:
Gradle将依赖项添加到编译类路径并生成输出。当模块包含api依赖项时,它会让Gradle知道该模块希望将该依赖项可传递地导出到其他模块,以便它们在运行时和编译时都可用。
