启用Proguard后获取com.loopj.android.http.AsyncHttpClient

Question

I have read this , It looks like its a known issue from quite some time. But i was not receiving any warning or crash when i was not using pro-guard . After enabling it, I am receiving around 500 warnings like following;

Warning:com.loopj.android.http.AsyncHttpClient: can't find referenced class cz.msebera.android.httpclient

I have tried following, but still all of the warnings are there.

android {

    compileSdkVersion 24
    buildToolsVersion "24.0.3"
    useLibrary 'org.apache.http.legacy'

}

I am not using http-client library, but there may be some other library that I am using in my project is using this.
