android 库版本启动时崩溃

Question

我创建了一个依赖项的库，例如 dagger retrofit rxjava 等，在模块状态下它工作正常但是当我将它部署到 artifactory 并在一个新项目中编译它时，项目一开始就崩溃了。 .

这是堆栈：

E/AndroidRuntime: FATAL EXCEPTION: main

这是我的库依赖项：

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation 'com.google.firebase:firebase-messaging:11.0.4'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
    compile 'com.google.dagger:dagger:2.9'

    compile 'com.squareup.retrofit2:converter-gson:2.+'

    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.support:support-v4:23.4.0'
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.6.0'
    annotationProcessor 'com.google.dagger:dagger-compiler:2.9'
    provided 'javax.annotation:jsr250-api:1.0'
    compile 'com.evernote:android-job:1.1.8'
}

我的主要猜测是依赖关系不与 aar 文件或其他东西一起使用，有没有办法解决这个问题？在您的库中使用依赖项的最佳做法是什么？

非常感谢。

我遇到了同样的崩溃并通过将 Dagger 库添加到主项目来解决它 build.gradle:

dependencies {
    implementation(name:'libraryUsingDagger', ext:'aar')

    implementation 'com.google.dagger:dagger:2.21'
    annotationProcessor 'com.google.dagger:dagger-compiler:2.21'
}

Answer 2

将 android gradle 插件版本升级到 3.4.2 后，我遇到了同样的问题。以下选项之一可以提供帮助：

将 android gradle 插件版本降级到 3.3.2
将 android.enableR8=false 行添加到 gradle.properties
