【问题描述】：
我已经阅读了this，这似乎是很久以前的一个已知问题。但是当我不使用pro-guard 时，我没有收到任何警告或崩溃。启用后，我收到大约 500 条警告，如下所示；
警告：com.loopj.android.http.AsyncHttpClient：找不到引用 类 cz.msebera.android.httpclient
我已尝试关注，但仍然存在所有警告。
android {
compileSdkVersion 24
buildToolsVersion "24.0.3"
useLibrary 'org.apache.http.legacy'
}
我没有使用 http-client 库，但我在项目中使用的其他库可能正在使用它。
