java.lang.NoClassDefFoundError: Failed resolution of: Lretrofit2/Callback

[VIROSOFT]

implementation 'co.paystack.android:paystack:3.0.17' implementation 'co.paystack.android.design.widget:pinpad:1.0.4'

After updating to the above version, which I believe is the latest version, my app ran quite alright (the last few versions of Paystack sdk had previously prevented it from running), but now the app crash at the point where I called "PaystackSdk.chargeCard()" in my code. The degub message is as follows:

java.lang.NoClassDefFoundError: Failed resolution of: Lretrofit2/Callback; at co.paystack.android.Paystack.chargeCard(Paystack.java:67)... Caused by: java.lang.ClassNotFoundException: Didn't find class "retrofit2.Callback" on path: DexPathList

Please help fix this, and please ensure every release of the sdk is thoroughly tested and debugged before releasing to public. The last three versions before this all had one issue or the other. I do hope the next version will be stable.

I've had to downgrade back to: implementation 'co.paystack.android:paystack:3.0.11'

It's the only stable version working for me.

I have been battling this same error for a few days. If not for this raised issue, they wouldn't respond via mail. Really not nice.

That's the full stacktrace

This issue should be fixed in newer versions of the SDK. I'm closing this now. Please open a new issue if you run into any problems.
