Question

我创建了一个新的android项目，并在项目内部创建了新的库模块(网络(。

现在我们有了应用程序(默认模块(和网络模块。

在网络模块中，我有截击依赖性，这在应用程序模块中是不存在的。

创建Kotlin类并在网络模块中定义此方法

/网络模块/

build.gradle

apply plugin: 'com.android.library'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
android {
compileSdkVersion 28
defaultConfig {
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
consumerProguardFiles 'consumer-rules.pro'
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = "1.8"
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.core:core-ktx:1.2.0'
// Volley Network
implementation 'com.android.volley:volley:1.1.1'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

//VolleyUtils.kt

class VolleyUtils {
fun enableLog() {
VolleyLog.DEBUG = true
}
}

从网络模块创建AAR，并将其放置在应用程序模块中

应用程序模块

build.gradle

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.test.base"
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = "1.8"
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.core:core-ktx:1.2.0'
implementation(name: 'volleynetwork-release', ext: 'aar')
//    implementation project(':volleynetwork')
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

//主要活动.kt

class MainActivity : AppCompatActivity() {
super.onreate(saveInstanceState)
setContentView(R.layout.activity_main)
//access method in network module
VolleyUtils().enableLog()
}
}

编译成功。但是，@Runtime导致异常

结果：

因此，只有当AAR生成时，问题才会出现，否则它会正常工作请指引我哪里出了问题。

Answer 1

在应用程序的build.gradle中添加以下内容：

implementation(project(":Name_of_your_network_module"))

注意：保留"："一开始

编辑

尝试将Network Module中的Volley依赖项从implementation更改为api。

Answer 2

添加您的aar，导入网络模块aar，然后只需在build.gradle应用程序模块中再次将截击依赖项添加到您的基础项目中。

依赖项｛

implementation‘com.android.solicy:solicy:1.1.1’

}

由于aar可能是HurlStack的一些依赖文件被删除
