java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/http/util/ByteArrayBuffer 错误处理

这事发生在使用最新版本Android Studio（3.2.1）使用targetSdkVersion 28集成讯飞语音合成或百度语音合成时出现：

E/AndroidRuntime: FATAL EXCEPTION: Thread-24

大致错误就是找不到org.apache.http.util.ByteArrayBuffer之类的，解决方法为在AndroidManifest.xml的<application>中加入以下代码：

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

请尝试上述方案是否能够解决，希望能帮到你。
