Getting Can't find common super class of [com/loopj/android/http/MySSLSocketFactory] after enabling Pro-guard

Question

After enabling pro-guard, I was receiving around 1000 warnings. So after adding rules and following this and this answers on Stackoverflow, I am now receiving 1 warning and 1 error.

This is what i am getting now.

Warning:Exception while processing task java.io.IOException: java.lang.IllegalArgumentException: Can't find common super class of [com/loopj/android/http/MySSLSocketFactory] (with 1 known super classes) and [java/security/KeyStore] (with 2 known super classes) Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.

java.io.IOException: java.lang.IllegalArgumentException: Can't find common super class of [com/loopj/android/http/MySSLSocketFactory] (with 1 known super classes) and [java/security/KeyStore] (with 2 known super classes)

android {

    compileSdkVersion 25
    buildToolsVersion "24.0.3"
    useLibrary 'org.apache.http.legacy'

}

EDIT

This is how i am enabling pro-guard in app build.gralde file, I am using 'proguard-android-optimize.txt

 buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

Answer 1

add this:

-keep class cz.msebera.android.httpclient.** { *; }
-dontwarn cz.msebera.android.httpclient.**

Update: try this:

-keep class com.loopj.android.** { *; }
-keep interface com.loopj.android.** { *; }
-keep class cz.msebera.android.** { *; }
-keep interface cz.msebera.android.** { *; }
-dontwarn cz.msebera.android.**
-dontwarn com.loopj.android.**
