Are you targetting MarshMallow? Please check your build.gradlefile. If it includes minSdkVersion=23then you will have to also include the following in your build file.

您的目标是 MarshMallow 吗？请检查您的build.gradle文件。如果包含，minSdkVersion=23则您还必须在构建文件中包含以下内容。

android {
    useLibrary 'org.apache.http.legacy'
}

The Apache libraries were deprecated and removed from the Android SDK in Android MarshMallow. Read more about this here: https://developer.android.com/about/versions/marshmallow/android-6.0-changes.html

Apache 库已弃用并从 Android MarshMallow 的 Android SDK 中删除。在此处阅读更多相关信息：https: //developer.android.com/about/versions/marshmallow/android-6.0-changes.html

I had a similar problem when using 'org.apache.http.client' in Android Studio with Gradle. If you're using the latest build tools i.e. SDK 23 then this library is depreciated.

在带有 Gradle 的 Android Studio 中使用“org.apache.http.client”时，我遇到了类似的问题。如果您使用的是最新的构建工具，即 SDK 23，则此库已贬值。

To get around this you can include it another way and it should still work with the latest build tools / SDK:

为了解决这个问题，你可以用另一种方式包含它，它应该仍然适用于最新的构建工具/SDK：

dependencies {
    compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
}
