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

I tried -dontwarn org.apache.lang.**, but still am getting the same issue

Can any please help me to recover this problem.

@IntelliJAmiya I think he wants to enable proguard so `minifyEnabled` should be `true` — hehe, Feb 10 '16 at 08:33
I think you should first clear the issues that are shown at the error report.... — Opiatefuchs, Feb 10 '16 at 08:42

For your google play services proguard problem refer here com.google.android.gms.internal.zzhu: can't find referenced class android.security.NetworkSecurityPolicy

And also try to resolve the manifest duplication issues or you can disable lint in release build.. to disable the lint check in release build add this to your build.gradle file

lintOptions {
        checkReleaseBuilds false
    }

try updating the play services version in build.gradle

compile 'com.google.android.gms:play-services-analytics:8.3.0'

According to the warning log that you have posted, it seems that the warning came from the package com.google.android.gms.internal.zzhu and not from org.apache.lang.

So to remove the warning add this in your proguard-rules.pro.

-dontwarn com.google.android.**

Tell us what happened then!
