Android 安卓截击签名Apk问题

我正在使用一个应用程序，在这个应用程序中，我将volley plus与android studio一起使用。我使用的是volley plus gradle版本的“dev.dworks.libs:volleyplus:+”gradle。当我对我的应用程序进行签名apk时，我的构建过程终止，出现一些警告和错误，runProguard为true。有任何解决办法

在ProGuard中使用此代码：

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

---

由于android API 23 Apache HTTP客户端已从android中删除： 但Volley仍然使用它，这就是为什么会有关于找不到引用类的警告 我们可以忽略这些警告，因为Volley仍然使用API 22编译：

如果将来Volley不更新，还应该考虑其他更好的库，比如OkHttp，它使用HttpURLConnection。

感谢您的详细解释！仅仅无视这些警告并不能让我确信这一点
