Answer 1

使用此代码的ProGuard：

-dontwarn org.apache.http.** 
-dontwarn android.net.http.AndroidHttpClient 
-dontwarn com.google.android.gms.** 
-dontwarn com.android.volley.toolbox.** 

Answer 2

由于Android API 23 Apache的HTTP客户端在Android中移除： https://developer.android.com/about/versions/marshmallow/android-6.0-changes.html#behavior-apache-http-client 但排球仍然使用它，这就是为什么有被警告不能找到引用类 我们可以忽略这些警告，因为Volley仍然使用API​​ 22进行编译： https://github.com/mcxiaoke/android-volley/blob/master/gradle.properties 还应该考虑其他更好的libray，如OkHttp，它使用HttpURLConnection，如果Volley做未来将不会更新。
