为什么警告:找不到可选库:org.apache.http.legacy?

问题描述

我的gradle文件:

My gradle file:

apply plugin: 'com.android.application'

android {
  useLibrary 'org.apache.http.legacy'
  compileSdkVersion 23
  buildToolsVersion "23.0.0"

  defaultConfig {
    applicationId "com.skripsi.irwanto.paud"
    minSdkVersion 15
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
  }

  buildTypes {
    release {
      minifyEnabled false
      proguardFiles getDefaultProauardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }
}
dependencies {
 compile fileTree(include: ['*.jar'], dir: 'libs')
 testCompile 'junit:junit:4.12'
 compile 'com.android.support:appcompat-v7:23.1.11
}

然后我得到Warning:Unable to find optional library: org.apache.http.legacy

推荐答案

我猜想，无需重新安装SDK即可更轻松地解决此问题的方法是在<sdk-path>\platforms\android-23\optional\目录中创建一个名为optional.json的文件，其中包含以下内容内容:

I guess, the easier way to solve this issue without having to reinstall the SDK is to create a file called optional.json in <sdk-path>\platforms\android-23\optional\ directory with the following content:

[
  {
    "name": "org.apache.http.legacy",
    "jar": "org.apache.http.legacy.jar",
    "manifest": false
  }
]

它为我解决了这个问题.

It solved the problem for me.

编辑:以下信息来自@domoch，有关如何找到您的SDK位置

EDIT: Information taken from @domoch's answer below on how to locate your SDK location

转到Android Studio Settings -> Appearence & Behavior -> System Settings并查找Android SDK Location.在Windows中，通常会指向C:\Users\<username>\AppData\Local\Android\sdk.

Go to Android Studio Settings -> Appearence & Behavior -> System Settings and look for Android SDK Location. In Windows, it usually would be pointing to C:\Users\<username>\AppData\Local\Android\sdk.
