Crash for FORTSDKv1.6.1

[riocallos]

Experienced a crash when my build settings are
minifyEnabled true
shrinkResources true

java.lang.IllegalAccessError: Field 'org.apache.commons.codec.binary.Base64.CHUNK_SEPARATOR' is inaccessible to class 'com.payfort.sdk.android.dependancies.security.aes.AESCipher' (declaration of 'com.payfort.sdk.android.dependancies.security.aes.AESCipher' appears in base.apk!classes2.dex) at com.payfort.sdk.android.dependancies.security.aes.AESCipher.getDecryptedMessage(AESCipher.java:7) at com.payfort.sdk.android.dependancies.security.aes.AESCipherManager.decryptMsg(AESCipherManager.java:2) at com.payfort.fort.android.sdk.activities.InitSecureConnectionActivity$Handshake.onPostExecute(InitSecureConnectionActivity.java:3) at com.payfort.fort.android.sdk.activities.InitSecureConnectionActivity$Handshake.onPostExecute(InitSecureConnectionActivity.java:1) at android.os.AsyncTask.finish(AsyncTask.java:695) at android.os.AsyncTask.access$600(AsyncTask.java:180) at android.os.AsyncTask$InternalHandler.handleMessage(AsyncTask.java:712) at android.os.Handler.dispatchMessage(Handler.java:106) at android.os.Looper.loop(Looper.java:193) at android.app.ActivityThread.main(ActivityThread.java:6669) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:493) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858)

this is how my proguard-rules.pro looks

-keep class othercode.** { ; }
-dontwarn com.payfort.*
-keep class com.payfort.** { ; }
-keep public interface com.payfort.* {*;}
-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application

Hi Riocallos,

Can you please check and make sure you are including all our Proguard rules included in our SDK file?
Attached our Proguard must be added in the application.

if that did not solve the problem, please share the proguard added in your application.
for any further assistance, please contact us directly on "[email protected]"

Hello,

Actually the progaurd.txt you attached produces a compile error in Android studio for the last three lines.
Expected [!]interface|@interface|class|enum

I can confirm that I have the same proguard as the one you've sent (after fixing the error). I'm attaching it here. Still experiencing the same crash.

Hello,

Applied the new proguard you attached. Still the same crash/error.
