我刚刚将项目转换为androidx,现在com.google.common.util.concurrent.ListenableFuture
收到“程序类型已存在”错误。
我浏览了多个stackoverflow解决方案和一些Gradle文档,但仍然无法正常工作。
问题在于,在这些模块中,Gradle引入了两个版本的ListenableFuture:
Gradle: com.google.quava:quava:23.5jre@jar
Gradle: com.google.guava:listenablefuture:1.0@jar
我猜想我想排除第二个,但无法弄清楚该怎么做。
您可以在gradle文件中看到我尝试过的内容,但到目前为止没有任何乐趣。
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.drme.weathertest"

}
}
}

}
如果我正确查看了依赖项,则看起来它来自
androidx.core:core:1.1.0-alpha03
。+--- androidx.core:core:1.1.0-alpha03@aar
+--- androidx.concurrent:concurrent-futures:1.0.0-alpha02@jar
+--- com.google.guava:listenablefuture:1.0@jar
建议将不胜感激。谢谢。
最佳答案
找到了问题和答案。在“项目” View 中查看外部库,我发现了以下内容:
Gradle: com.google.guava:guava:23.5-jre@jar
|_ guava-23.5-jre.jar
|_com.google
|_common
|_util.concurrent
|_ListenableFuture
Gradle: com.google.guava:listenablefuture:1.0@jar
|_listenablefuture-1.0.jar
|_com.google.common.util.concurrent
|_ListenableFuture
第二个条目中唯一的东西是重复的ListenableFuture。
通过在gradle构建文件中进行以下输入,此问题消失了:
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == "com.android.support") {
if (!requested.name.startsWith("multidex")) {
details.useVersion "26.+"
}
}
}
all*.exclude group: 'com.google.guava', module: 'listenablefuture' <===This fixed the problem
}
我不知道是什么生成了
com.google.guava:listenablefuture:1.0@jar
,但是解决了所产生的问题。感谢所有审查此问题的人。
关于android - 程序类型已经存在: com. google.common.util.concurrent.ListenableFuture,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/54174685/
