title: Is there any proguard rules should use while using EncryptedSharedPreferences?
body: <p>before using <strong>EncryptedSharedPreferences</strong> my app works fine in <strong>release</strong> mode with (minifyEnabled = true), After adding the <a href="https://developer.android.com/topic/security/data" rel="noreferrer">security library</a> <strong>(version 1.0.0-rc01)</strong> to my application the app crash while opening and if i use (minifyEnabled = false) the app works fine, i think i missing something to add it in <strong>proguard-rules.pro</strong> but i have searched a lot did not found anything. </p>
