Android9.0_P:ClassNotFoundException: Didn't find class "org.apache.http.conn.scheme.SchemeRegistry"

出现此问题的机型:一加7Pro，系统版本为:9。

解决方案见官方文档:https://developer.android.google.cn/about/versions/pie/android-9.0-changes-28

Apache HTTP 客户端弃用

在 Android 6.0 中，我们取消了对 Apache HTTP 客户端的支持。 从 Android 9 开始，默认情况下该内容库已从 bootclasspath 中移除且不可用于应用。

要继续使用 Apache HTTP 客户端，以 Android 9 及更高版本为目标的应用可以向其 AndroidManifest.xml的application节点下 添加以下内容：

<uses-library android:name="org.apache.http.legacy" android:required="false"/>

 <application
        android:name=".MyApp"
        android:allowBackup="true" 
       android:icon="@mipmap/ic_launcher" 
       android:label="@string/app_name" 
       android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
         <uses-library
            android:name="org.apache.http.legacy"
            android:required="false" />
                <activity
            android:name=".DisplayActivity"
            android:configChanges="screenSize|orientation|keyboardHidden"> 
           <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                 <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
  </application>

注：拥有最低 SDK 版本 23 或更低版本的应用需要 android:required="false" 属性，因为在 API 级别低于 24 的设备上，org.apache.http.legacy 库不可用。 （在这些设备上，Apache HTTP 类在 bootclasspath 中提供。）

作为使用运行时 Apache 库的替代，应用可以在其 APK 中绑定自己的 org.apache.http 库版本。 如果进行此操作，您必须将该库重新打包（使用一个类似 Jar Jar 的实用程序）以避免运行时中提供的类存在类兼容性问题。
