Android Volley Signed Apk Issue

I am working with an application where I am using volley plus with android studio. I am using volley plus gradle version 'dev.dworks.libs:volleyplus:+' gradle. When I make signed apk of my app my build process terminated with some warning and errors with runProguard true. There is any solution to solve this.

Use this code in ProGuard:

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

Since android API 23 Apache HTTP Client is removed from Android: https://developer.android.com/about/versions/marshmallow/android-6.0-changes.html#behavior-apache-http-client But Volley still uses it, that's why there is warn about can't find referenced class We can ignore these warns, because Volley is still compiled using API 22: https://github.com/mcxiaoke/android-volley/blob/master/gradle.properties Still should think about other better libray like OkHttp, which uses HttpURLConnection, if Volley doesn't update in the future.
